Summary:
All ctl_table declared outside of functions and that remain unmodified after initialization are const qualified. This prevents unintended modifications to proc_handler function pointers by placing them in the .rodata section. This is a continuation of the tree-wide effort started a few releases ago with the constification of the ctl_table struct arguments in the sysctl API done in |

KVM/arm64 updates for 6.14
* New features:
- Support for non-protected guest in protected mode, achieving near
feature parity with the non-protected mode
- Support for the EL2 timers as part of the ongoing NV support
- Allow control of hardware tracing for nVHE/hVHE
* Improvements, fixes and cleanups:
- Massive cleanup of the debug infrastructure, making it a bit less
awkward and definitely easier to maintain. This should pave the
way for further optimisations
- Complete rewrite of pKVM's fixed-feature infrastructure, aligning
it with the rest of KVM and making the code easier to follow
- Large simplification of pKVM's memory protection infrastructure
- Better handling of RES0/RES1 fields for memory-backed system
registers
- Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer
from a pretty nasty timer bug
- Small collection of cleanups and low-impact fixes

treewide: const qualify ctl_tables where applicable
Add the const qualifier to all the ctl_tables in the tree except for
watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,
loadpin_sysctl_table and the ones calling register_net_sysctl (./net,
drivers/inifiniband dirs). These are special cases as they use a
registration function with a non-const qualified ctl_table argument or
modify the arrays before passing them on to the registration function.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit

mm/memblock: add memblock_alloc_or_panic interface
Before SLUB initialization, various subsystems used memblock_alloc to allocate memory. In most cases, when memory allocation fails, an immediate panic is required. To simplify this behavior and reduce repetitive checks, introduce `memblock_alloc_or_panic`. This function ensures that memory allocation failures result in a panic automatically, improving code readability and consistency across subsystems that require this behavior.

asm-generic: pgalloc: provide generic __pgd_{alloc,free}
We already have a generic implementation of alloc/free up to P4D level, as
well as pgd_free(). Let's finish the work and add a generic PGD-level
alloc helper as well.
Unlike at lower levels, almost all architectures need some specific magic
at PGD level (typically initialising PGD entries), so introducing a
generic pgd_alloc() isn't worth it. Instead we introduce two new helpers,
__pgd_alloc() and __pgd_free(), and make use of them in the arch-specific
pgd_alloc() and pgd_free() wherever possible. To accommodate as many arch
as possible, __pgd_alloc() takes a page allocation order.
Because pagetable_alloc() allocates zeroed pages, explicit zeroing in
pgd_alloc() becomes redundant and we can get rid of it. Some trivial
implementations of pgd_free() also become unnecessary once __pgd_alloc()
is used; remove them.
Another small improvement is consistent accounting of PGD pages by using
GFP_PGTABLE_{USER,KERNEL} as appropriate.
Not all PGD allocations can be handled by the generic helpers. In
particular, multiple architectures allocate PGDs from a kmem_cache, and
those PGDs may not be page-sized.

arm64: pgtable: move pagetable_dtor() to __tlb_remove_table()
Move pagetable_dtor() to __tlb_remove_table(), so that ptlock and page table pages can be freed together (regardless of whether RCU is used). This prevents the use-after-free problem where the ptlock is freed immediately but the page table pages is freed later via RCU. Page tables shouldn't have swap cache, so use pagetable_free() instead of free_page_and_swap_cache() to free page table pages.

mm: pgtable: introduce pagetable_dtor()
The pagetable_p*_dtor() are exactly the same except for the handling of ptlock. If we make ptlock_free() handle the case where ptdesc->ptl is NULL and remove VM_BUG_ON_PAGE() from pmd_ptlock_free(), we can unify pagetable_p*_dtor() into one function. Let's introduce pagetable_dtor() to do this. Later, pagetable_dtor() will be moved to tlb_remove_ptdesc(), so that ptlock and page table pages can be freed together (regardless of whether RCU is used). This prevents the use-after-free problem where the ptlock is freed immediately but the page table pages is freed later via RCU.

asm-generic: pgalloc: provide generic p4d_{alloc_one,free}
Four architectures currently implement 5-level pgtables: arm64, riscv, x86 and s390. The first three have essentially the same implementation for p4d_alloc_one() and p4d_free(), so we've got an opportunity to reduce duplication like at the lower levels. Provide a generic version of p4d_alloc_one() and p4d_free(), and make use of it on those architectures. Their implementation is the same as at PUD level, except that p4d_free() performs a runtime check by calling mm_p4d_folded(). 5-level pgtables depend on a runtime-detected hardware feature on all supported architectures, so we might as well include this check in the generic implementation. No runtime check is required in p4d_alloc_one() as the top-level p4d_alloc() already does the required check.

Loongarch:
* Clear LLBCTL if secondary mmu mapping changes.
* Add hypercall service support for usermode VMM.
x86:
* Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a
direct call to kvm_tdp_page_fault() when RETPOLINE is enabled.
* Ensure that all SEV code is compiled out when disabled in Kconfig, even
if building with less brilliant compilers.
* Remove a redundant TLB flush on AMD processors when guest CR4.PGE changes.
* Use str_enabled_disabled() to replace open coded strings.
* Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache
prior to every VM-Enter.
* Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities
instead of just those where KVM needs to manage state and/or explicitly
enable the feature in hardware. Along the way, refactor the code to make
it easier to add features, and to make it more self-documenting how KVM
is handling each feature.
* Rework KVM's handling of VM-Exits during event vectoring; this plugs holes
where KVM unintentionally puts the vCPU into infinite loops in some scenarios
(e.g. if emulation is triggered by the exit), and brings parity between VMX
and SVM.
* Add pending request and interrupt injection information to the kvm_exit and
kvm_entry tracepoints respectively.
* Fix a relatively benign flaw where KVM would end up redoing RDPKRU when
loading guest/host PKRU, due to a refactoring of the kernel helpers that
didn't account for KVM's pre-checking of the need to do WRPKRU.
* Make the completion of hypercalls go through the complete_hypercall
function pointer argument, no matter if the hypercall exits to
userspace or not. Previously, the code assumed that KVM_HC_MAP_GPA_RANGE
specifically went to userspace, and all the others did not; the new code
need not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at
all whether there was an exit to userspace or not.
* As part of enabling TDX virtual machines, support support separation of
private/shared EPT into separate roots. When TDX will be enabled, operations
on private pages will need to go through the privileged TDX Module via SEAMCALLs;
as a result, they are limited and relatively slow compared to reading a PTE.
The patches included in 6.14 allow KVM to keep a mirror of the private EPT in
host memory, and define entries in kvm_x86_ops to operate on external page
tables such as the TDX private EPT.
* The recently introduced conversion of the NX-page reclamation kthread to
vhost_task moved the task under the main process. The task is created as
soon as KVM_CREATE_VM was invoked and this, of course, broke userspace that
didn't expect to see any child task of the VM process until it started
creating its own userspace threads. In particular crosvm refuses to fork()
if procfs shows any child task, so unbreak it by creating the task lazily.
This is arguably a userspace bug, as there can be other kinds of legitimate
worker tasks and they wouldn't impede fork(); but it's not like userspace
has a way to distinguish kernel worker tasks right now. Should they show
as "Kthread: 1" in proc/.../status?
x86 - Intel:
* Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit
while L2 is active, while ultimately results in a hardware-accelerated L1
EOI effectively being lost.
* Honor event priority when emulating Posted Interrupt delivery during nested
VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the
interrupt.
* Rework KVM's processing of the Page-Modification Logging buffer to reap
entries in the same order they were created, i.e. to mark gfns dirty in the
same order that hardware marked the page/PTE dirty.
* Misc cleanups.
Generic:
* Cleanup and harden kvm_set_memory_region(); add proper lockdep assertions when
setting memory regions and add a dedicated API for setting KVM-internal
memory regions. The API can then explicitly disallow all flags for
KVM-internal memory regions.
* Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug
where KVM would return a pointer to a vCPU prior to it being fully online,
and give kvm_for_each_vcpu() similar treatment to fix a similar flaw.
* Wait for a vCPU to come online prior to executing a vCPU ioctl, to fix a
bug where userspace could coerce KVM into handling the ioctl on a vCPU that
isn't yet onlined.
* Gracefully handle xarray insertion failures; even though such failures are
impossible in practice after xa_reserve(), reserving an entry is always followed
by xa_store() which does not know (or differentiate) whether there was an
xa_reserve() before or not.
RISC-V:
* Zabha, Svvptc, and Ziccrse extension support for guests. None of them
require anything in KVM except for detecting them and marking them
as supported; Zabha adds byte and halfword atomic operations, while the
others are markers for specific operation of the TLB and of LL/SC
instructions respectively.
* Virtualize SBI system suspend extension for Guest/VM
* Support firmware counters which can be used by the guests to collect
statistics about traps that occur in the host.
Selftests:
* Rework vcpu_get_reg() to return a value instead of using an out-param, and
update all affected arch code accordingly.
* Convert the max_guest_memory_test into a more generic mmu_stress_test.
The basic gist of the "conversion" is to have the test do mprotect() on
guest memory while vCPUs are accessing said memory, e.g. to verify KVM
and mmu_notifiers are working as intended.
* Play nice with treewrite builds of unsupported architectures, e.g. arm
(32-bit), as KVM selftests' Makefile doesn't do anything to ensure the
target architecture is actually one KVM selftests supports.
* Use the kernel's $(ARCH) definition instead of the target triple for arch
specific directories, e.g. arm64 instead of aarch64, mainly so as not to
be different from the rest of the kernel.
* Ensure that format strings for logging statements are checked by the
compiler even when the logging statement itself is disabled.
* Attempt to whack the last LLC references/misses mole in the Intel PMU
counters test by adding a data load and doing CLFLUSH{OPT} on the data
instead of the code being executed. It seems that modern Intel CPUs
have learned new code prefetching tricks that bypass the PMU counters.
* Fix a flaw in the Intel PMU counters test where it asserts that events
are counting correctly without actually knowing what the events count
given the underlying hardware; this can happen if Intel reuses a
formerly microarchitecture-specific event encoding as an architectural
event, as was the case for Top-Down Slots.

soc: devicetree changes for 6.14
We see the addition of eleven new SoCs, including a total of sixx arm64
chips from Qualcomm alone. Overall, the Qualcomm platforms once again
make up the majority of all changes, after a couple of quieter releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of
the V4H (R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips
using Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial
IOT platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that
only need new devicetree files. Two additional SoCs in new
families are part of a separate branch.
There are 48 new machines in total, including six arm32 ones based
on aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores,
and a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP, Mediatek,
Qualcomm, Renesas and Rockchips and cover development boards, phones,
laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features.

Pull SoC devicetree updates from Arnd Bergmann:
"We see the addition of eleven new SoCs, including a total of sixx
arm64 chips from Qualcomm alone. Overall, the Qualcomm platforms once
again make up the majority of all changes, after a couple of quieter
releases.
The new SoCs in this branch are:
- Microchip sama7d65 is a new 32-bit embedded chip with a single
Cortex-A7 and the current high end of the old Atmel SoC line.
- Samsung Exynos 9810 is a mobile phone chip used in some older
phones like the Samsung Galaxy S9
- Renesas R-Car V4H ES3.0 (R8A779G3) is an updated version of the V4H
(R8A779G0) low-power automotive SoC
- Renesas RZ/G3E (R0A09G047) is a family of embedded chips using
Cortex-A55 cores
- Qualcomm Snapdragon 8 Elite (SM8750) is a new phone chip based on
Qualcomm's Oryon CPU cores.
- Qualcomm Snapdragon AR2 (SAR2130P) is a SoC for augmented reality
glasses.
- Qualcomm IQ6 (QCS610) and IQ8 (QCS8300) are two industrial IOT
platforms.
- Snapdragon 425 (MSM8917) is a mobile phone SoC from 2016
- Qualcomm IPQ5424 is a Wi-Fi 7 networking chip
All of the above are part of already supported SoC families that only
need new devicetree files. Two additional SoCs in new families are
part of a separate branch.
There are 48 new machines in total, including six arm32 ones based on
aspeed. broadcom, microchip and st SoCs all using Cortex-A7 cores, and
a single risc-v board, the Banana Pi R3.
The remaining ones use arm64 chips from Broadcom, Samsung, NXP,
Mediatek, Qualcomm, Renesas and Rockchips and cover development
boards, phones, laptops, industrial machines routers.
A lot of ongoing work is for cleaning up build time warnings and other
issues, in addition to the new machines and added features"

soc: new SoC support for 6.14
Two new SoC families are added here, with devicetree files and
a little bit of infrastructure to allow booting:
- Blaize BLZP1600 is an AI chip using custom GSP (Graph Streaming
Processor) cores for computation, and two small Cortex-A53 cores
that run the operating system.
- SpacemiT K1 is a 64-bit RISC-V chip, using eight custom RVA22
compatible CPU cores with vector support.
Also marketed at AI applications, it has a much slower NPU compared
to BLZP1600, but in turn focuses on the CPU performance

Pull bpf updates from Alexei Starovoitov:
"A smaller than usual release cycle.
The main changes are:
- Prepare selftest to run with GCC-BPF backend (Ihor Solodrai)
In addition to LLVM-BPF runs the BPF CI now runs GCC-BPF in compile
only mode. Half of the tests are failing, since support for
btf_decl_tag is still WIP, but this is a great milestone.
- Convert various samples/bpf to selftests/bpf/test_progs format
(Alexis Lothoré and Bastien Curutchet)
- Teach verifier to recognize that array lookup with constant
in-range index will always succeed (Daniel Xu)
- Cleanup migrate disable scope in BPF maps (Hou Tao)
- Fix bpf_timer destroy path in PREEMPT_RT (Hou Tao)
- Always use bpf_mem_alloc in bpf_local_storage in PREEMPT_RT (Martin
KaFai Lau)
- Refactor verifier lock support (Kumar Kartikeya Dwivedi)
This is a prerequisite for upcoming resilient spin lock.
- Remove excessive 'may_goto +0' instructions in the verifier that
LLVM leaves when unrolls the loops (Yonghong Song)
- Remove unhelpful bpf_probe_write_user() warning message (Marco
Elver)
- Add fd_array_cnt attribute for prog_load command (Anton Protopopov)
This is a prerequisite for upcoming support for static_branch"

CRC updates for 6.14
- Reorganize the architecture-optimized CRC32 and CRC-T10DIF code to be directly accessible via the library API, instead of requiring the crypto API. This is much simpler and more efficient. - Convert some users such as ext4 to use the CRC32 library API instead of the crypto API. More conversions like this will come later. - Add a KUnit test that tests and benchmarks multiple CRC variants. Remove older, less-comprehensive tests that are made redundant by this. - Add an entry to MAINTAINERS for the kernel's CRC library code. I'm volunteering to maintain it.

A pretty quiet cycle this time around. We have a bunch of new Qualcomm clk
drivers, per usual, and then a handful of drivers for other SoCs. Then the
usual pile of cleanups is fairly small data fixes or converting DT bindings to
YAML so they can be validated. No changes to the core framework besides an OF
node refcount bump that never got decremented.
New Drivers:
- 5L35023 variant of Versa 3 clock generator
- Various Qualcomm clk controllers: IPQ CMN PLL, SM6115 LPASS, SM750 global,
tcsr, rpmh, and display. X Plus GPU and global. QCS615 rpmh and MSM8937 and
MSM8940 RPM.
- Qualcomm Pongo and Taycan Alpha PLLs
- Qualcomm IPQ5424 NoC-related interconnect clks
- Renesas RZ/G3E (R9A09G047) SoC clk driver
- SAMA7D65 SoC clk driver

Kthreads affinity follow either of 4 existing different patterns:
1) Per-CPU kthreads must stay affine to a single CPU and never execute
relevant code on any other CPU. This is currently handled by smpboot
code which takes care of CPU-hotplug operations. Affinity here is
a correctness constraint.
2) Some kthreads _have_ to be affine to a specific set of CPUs and can't
run anywhere else. The affinity is set through kthread_bind_mask()
and the subsystem takes care by itself to handle CPU-hotplug
operations. Affinity here is assumed to be a correctness constraint.
3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This
is not a correctness constraint but merely a preference in terms of
memory locality. kswapd and kcompactd both fall into this category.
The affinity is set manually like for any other task and CPU-hotplug
is supposed to be handled by the relevant subsystem so that the task
is properly reaffined whenever a given CPU from the node comes up.
Also care should be taken so that the node affinity doesn't cross
isolated (nohz_full) cpumask boundaries.
4) Similar to the previous point except kthreads have a _preferred_
affinity different than a node. Both RCU boost kthreads and RCU
exp kworkers fall into this category as they refer to "RCU nodes"
from a distinctly distributed tree.
Currently the preferred affinity patterns (3 and 4) have at least 4
identified users, with more or less success when it comes to handle
CPU-hotplug operations and CPU isolation. Each of which do it in its own
ad-hoc way.
This is an infrastructure proposal to handle this with the following API
changes:
_ kthread_create_on_node() automatically affines the created kthread to
its target node unless it has been set as per-cpu or bound with
kthread_bind[_mask]() before the first wake-up.
- kthread_affine_preferred() is a new function that can be called right
after kthread_create_on_node() to specify a preferred affinity
different than the specified node.
When the preferred affinity can't be applied because the possible
targets are offline or isolated (nohz_full), the kthread is affine
to the housekeeping CPUs (which means to all online CPUs most of the
time or only the non-nohz_full CPUs when nohz_full= is set).
kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
converted, along with a few old drivers.
Summary of the changes:
* Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu()
* Introduce task_cpu_fallback_mask() that defines the default last
resort affinity of a task to become nohz_full aware
* Add some correctness check to ensure kthread_bind() is always called
before the first kthread wake up.
* Default affine kthread to its preferred node.
* Convert kswapd / kcompactd and remove their halfway working ad-hoc
affinity implementation
* Implement kthreads preferred affinity
* Unify kthread worker and kthread API's style
* Convert RCU kthreads to the new API and remove the ad-hoc affinity
implementation.

ftrace updates for v6.14:
- Have fprobes built on top of function graph infrastructure The fprobe logic is an optimized kprobe that uses ftrace to attach to functions when a probe is needed at the start or end of the function. The fprobe and kretprobe logic implements a similar method as the function graph tracer to trace the end of the function. That is to hijack the return address and jump to a trampoline to do the trace when the function exits. To do this, a shadow stack needs to be created to store the original return address. Fprobes and function graph do this slightly differently. Fprobes (and kretprobes) has slots per callsite that are reserved to save the return address. This is fine when just a few points are traced. But users of fprobes, such as BPF programs, are starting to add many more locations, and this method does not scale. The function graph tracer was created to trace all functions in the kernel. In order to do this, when function graph tracing is started, every task gets its own shadow stack to hold the return address that is going to be traced. The function graph tracer has been updated to allow multiple users to use its infrastructure. Now have fprobes be one of those users. This will also allow for the fprobe and kretprobe methods to trace the return address to become obsolete. With new technologies like CFI that need to know about these methods of hijacking the return address, going toward a solution that has only one method of doing this will make the kernel less complex. - Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated. But this is error prone. Convert the code over to use the guard() and free() helpers that let the compiler unlock locks or free memory when the function exits. - Remove disabling of interrupts in the function graph tracer When function graph tracer was first introduced, it could race with interrupts and NMIs. To prevent that race, it would disable interrupts and not trace NMIs. But the code has changed to allow NMIs and also interrupts. This change was done a long time ago, but the disabling of interrupts was never removed. Remove the disabling of interrupts in the function graph tracer is it is not needed. This greatly improves its performance. - Allow the :mod: command to enable tracing module functions on the kernel command line. The function tracer already has a way to enable functions to be traced in modules by writing ":mod:<module>" into set_ftrace_filter. That will enable either all the functions for the module if it is loaded, or if it is not, it will cache that command, and when the module is loaded that matches <module>, its functions will be enabled. This also allows init functions to be traced. But currently events do not have that feature. Because enabling function tracing can be done very early at boot up (before scheduling is enabled), the commands that can be done when function tracing is started is limited. Having the ":mod:" command to trace module functions as they are loaded is very useful. Update the kernel command line function filtering to allow it. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZ42E2RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqXSAPwOMxuhye8tb1GYG62QD9+w7e6nOmlC 2GCPj4detnEM2QD/ciivkhespVKhHpZHRewAuSnJgHPSM45NQ3EVESzjWQ4= =snbx -----END PGP SIGNATURE----- Merge tag 'ftrace-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Have fprobes built on top of function graph infrastructure The fprobe logic is an optimized kprobe that uses ftrace to attach to functions when a probe is needed at the start or end of the function.

Updates for the interrupt subsystem:
- Consolidation of the machine_kexec_mask_interrupts() by providing a
generic implementation and replacing the copy & pasta orgy in the
relevant architectures.
- Prevent unconditional operations on interrupt chips during kexec
shutdown, which can trigger warnings in certain cases when the
underlying interrupt has been shut down before.
- Make the enforcement of interrupt handling in interrupt context
unconditionally available, so that it actually works for non x86
related interrupt chips. The earlier enablement for ARM GIC chips set
the required chip flag, but did not notice that the check was hidden
behind a config switch which is not selected by ARM[64].
- Decrapify the handling of deferred interrupt affinity setting. Some
interrupt chips require that affinity changes are made from the context
of handling an interrupt to avoid certain race conditions. For x86 this
was the default, but with interrupt remapping this requirement was
lifted and a flag was introduced which tells the core code that
affinity changes can be done in any context. Unrestricted affinity
changes are the default for the majority of interrupt chips. RISCV has
the requirement to add the deferred mode to one of it's interrupt
controllers, but with the original implementation this would require to
add the any context flag to all other RISC-V interrupt chips. That's
backwards, so reverse the logic and require that chips, which need the
deferred mode have to be marked accordingly. That avoids chasing the
'sane' chips and marking them.
- Add multi-node support to the Loongarch AVEC interrupt controller
driver.
- The usual tiny cleanups, fixes and improvements all over the place.

Pull interrupt subsystem updates from Thomas Gleixner:
- Consolidate the machine_kexec_mask_interrupts() by providing a
generic implementation and replacing the copy & pasta orgy in the
relevant architectures.
- Prevent unconditional operations on interrupt chips during kexec
shutdown, which can trigger warnings in certain cases when the
underlying interrupt has been shut down before.
- Make the enforcement of interrupt handling in interrupt context
unconditionally available, so that it actually works for non x86
related interrupt chips. The earlier enablement for ARM GIC chips set
the required chip flag, but did not notice that the check was hidden
behind a config switch which is not selected by ARM[64].
- Decrapify the handling of deferred interrupt affinity setting.
Some interrupt chips require that affinity changes are made from the
context of handling an interrupt to avoid certain race conditions.
For x86 this was the default, but with interrupt remapping this
requirement was lifted and a flag was introduced which tells the core
code that affinity changes can be done in any context. Unrestricted
affinity changes are the default for the majority of interrupt chips.
RISCV has the requirement to add the deferred mode to one of it's
interrupt controllers, but with the original implementation this
would require to add the any context flag to all other RISC-V
interrupt chips. That's backwards, so reverse the logic and require
that chips, which need the deferred mode have to be marked
accordingly. That avoids chasing the 'sane' chips and marking them.
- Add multi-node support to the Loongarch AVEC interrupt controller
driver.
- The usual tiny cleanups, fixes and improvements all over the place.

: pKVM memory transition simplifications, courtesy of Quentin Perret.
:
: From the cover letter:
: "Since its early days, pKVM has formalized memory 'transitions' (shares
: and donations) using 'struct pkvm_mem_transition' and bunch of helpers
: to manipulate it. The intention was for all transitions to use this
: machinery to ensure we're checking things consistently. However, as
: development progressed, it became clear that the rigidity of this model
: made it really difficult to use in some use-cases which ended-up
: side-stepping it entirely. That is the case for the
: hyp_{un}pin_shared_mem() and host_{un}share_guest() paths upstream which
: use lower level helpers directly, as well as for several other pKVM
: features that should land upstream in the future (ex: when a guest
: relinquishes a page during ballooning, when annotating a page that is
: being DMA'd to, ...). On top of this, the pkvm_mem_transition machinery
: requires a lot of boilerplate which makes the code hard to read, but
: also adds layers of indirection that no compilers seems to see through,
: hence leading to suboptimal generated code.
:
: Given all the above, this series removes the pkvm_mem_transition
: machinery from mem_protect.c, and converts all its users to use
: __*_{check,set}_page_state_range() low-level helpers directly."

: Nested Virt support for the EL2 timers. From the initial cover letter:
:
: "Here's another batch of NV-related patches, this time bringing in most
: of the timer support for EL2 as well as nested guests.
:
: The code is pretty convoluted for a bunch of reasons:
:
: - FEAT_NV2 breaks the timer semantics by redirecting HW controls to
: memory, meaning that a guest could setup a timer and never see it
: firing until the next exit
:
: - We go try hard to reflect the timer state in memory, but that's not
: great.
:
: - With FEAT_ECV, we can finally correctly emulate the virtual timer,
: but this emulation is pretty costly
:
: - As a way to make things suck less, we handle timer reads as early as
: possible, and only defer writes to the normal trap handling
:
: - Finally, some implementations are badly broken, and require some
: hand-holding, irrespective of NV support. So we try and reuse the NV
: infrastructure to make them usable. This could be further optimised,
: but I'm running out of patience for this sort of HW.

arm64: tegra: Device tree fixes for v6.14-rc1
These patches fix up an issue with the DMA support on one of the SPI controllers, as well as properly identify the SCE fabric and disable it to prevent accessing registers that may not be accessible to the CPU. Finally, the GIC's #address-cells property is set to 0 to fix a problem in the PCIe interrupt-map property. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmeBX/wACgkQ3SOs138+ s6FJMQ//QTiQ/jZNgr3s1/jLCUW+y9mHywFzT8Oa746T18wf25cq3rjEE+C9j/VE ioogR/BEUGnCvwMRqculyCfsM72kgYor5X/olU1xcP4nTCj2x/X0mzud6xfPKS7b xvw4a9CHUgRs80c+nh7DqgMQrfxO/GFoSTMgCTDarrCNMOwavOStNUT63hqlN1tO cdoDe4fHFKL/sdXeD/wxKDNYrHgER47S4lIoeRgMVINCQ33h6bNByZeSMUR7btdX 29C8QhFdEbxvyolzvrbIChS6FgtEemZZM30lcrZmRwnuCJ1hV0xazzPzyS14CEES QtqGFgWxsX1YfMyN8jdORctMa2++zVsMq6iHorPSP3Nw8qO2jTDqs8ypNgEyYLOt 4hLk5oMVvFtCEvW0Su3iCsQOUSYKKtiAiwW92NaZxtqEgd+QvXiCl1dPAqXoseon V95dLTP2X4SMkwJoxb2M9pgS5A3XC6x3ZsDjRhqk456HYJkjcf0VG+iRblUe70DB 6NPEDgvfkPAz3iWH4Z6Y30xN1cUDbqWL11rzNTNuRYUa9viq4L4o3E4o/XEHh+J7 kZyZC+J3HYy3hXeh/6dPw61H+QLbY/s+tsN/B3IyYm/+yn15kQGteL683418luko PQ4vilBkzPve9la7Cc8uc/t4n3Fr5CPf76A7N+2yNM3HNGvePCk= =IIxY -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmeJFMkACgkQYKtH/8kJ Uic4Vg/7B4aPh20jS/k+zOs2jHqGap5Yt72jBpPDIbevT9Y2xZ4KSBV9excG0aYZ lLmVjNyfra2SpTh5GQnO9vULdLc7CPqS6DpflWO1n9bBnpNpoAuRaBAT/+udbm8Q ucC7h7ST78VkZ4zbzBkPtk6yMYovm9b1tPxsNRSOG1GSpqSWVAfvGIWvtuRlEELF NglFROn18aRTrZrZrMtHpOkT7ZixLKaUgeVO9sPPh02ouem+YVP25h7b0PQ+qSIL e5nlI3Vi60Q7f+gCuAPDc+Cf8UbnnwQPRLV3qkcv/nTY94783rpvj0i5t2Zy2zL6 Sp1Mo0Fe9k7p4iKmmWbf9z483W684a306Q7VQ+DtmaNPICvb+RqbPS+DqOFuhJAF gfDOehzRZ7xWTvVFGpfRgM+0Mb5ODAfm7JjXuPzB26pIHs8kmC8bwR1/DrHtUQ0w 6SWHKr6stzPulp9l/JwUY3HbXvbTlZfCc5yfo6Jyu7LwE8I+zfTPSMqoRmW1ub1b JiZ/3UyqhUq/pvrKqSR0RiVQBSZ3oPAEB1koKMufZ0vG4EjG8/9fLhr84u2AY+X5 2Psrx6KiXIclaiG3qd8IDsAlyQ2T2YolYJnypwz6mlWv/75xJAkAYbyiEyVq9/ew p+PhLF4Rof6hGgYBzbO8JX77Zi/1L81AfGsVXIWMk/4haG79Pvs= =wbJd -----END PGP SIGNATURE----- Merge tag 'tegra-for-6.14-arm64-dt' of https://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into soc/dt arm64: tegra: Device tree fixes for v6.14-rc1 These patches fix up an issue with the DMA support on one of the SPI controllers, as well as properly identify the SCE fabric and disable it to prevent accessing registers that may not be accessible to the CPU.

This pull request contains Broadcom ARM64-based SoCs Device Tree updates
for 6.14: - Dave adds the display pipeline DT nodes on BCM2712 (Raspberry Pi 5) - Rob removes some undocumented properties - Same ensures that the CFE stub area is reserved to allow secondary CPUs to be successfully brought up in Linux, also making sure that the address used in the spin table is also carved out. Finally he adds support for the Zyxel EX3510-B router using BCM4906 - Rosen converts the BCM4908 platforms to use the more flexible nvmem-layout representation -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEm+Rq3+YGJdiR9yuFh9CWnEQHBwQFAmeAFF4ACgkQh9CWnEQH BwT0GxAAky4zXzWxJfeBflilG4vKj9T9pYo9ECqgc7/EBGk8+JlXGZM0WqQmJiPs tngRySVW7AR9ZI7OwzcnLWyErKm4HgnN4tBPEUkJf12fmoUDNo/q0jw2CyRLw7Hi X7cYGE83iJI4WoDxAnI66AEDlSfbC0yoFLM4xzoW8lCsWDjhIG7D2naV1utpaWm4 MfdwEW6/oRZHL8Tm+2FCYXVl3rW68rrjbHQKN2r1nahyzBPhWkxDqjYwlXxZSYiv uVyY9SZPBhBadD7owCr2eGbXhwNAaclnqlPUud9YBJgIruRi6TeHjBC/53uQfLBS 0r5KZAC33NAjhjg8lfMaZMKmDzciUi3x3iNbMWskcsYPSgrAz9+GjOnoHyGgbWUs T7iGwMcWX1nG8SFhhkLtqWar8kSs5kZGXR25dFsn/uKHeIoDFq2gLDRFVfxanZXt jvVChgFRS3i27r4QARmLeWhdcfvM0mg4yVby1Ge14iQCPy6dFJlIHBKWVWQR5iRJ Oy56zmLT3xMfquE4A99YeJcSEkssHLDSY91AZoM73jvylnSpvEFWOMkYWiYBMten 5JLEe2hqd4r4WBBkNtvv6g1cyNrKKBND5cGSrOO+cCupGY9HZbJMlrzf4/M2CdGg E/y+VhISOCEZr9iqk0OMJ720AuAoGN7elLAkTAsP1os3sJPiO9Q= =Cpr3 -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmeJEzsACgkQYKtH/8kJ UifHUQ/+IK/7JxLvZ/5VEoCEFVHuvpUEUzQNNhzO5i5UzWYeJIijmhKpSoVmgS45 2SIB4FdjkeDr8S93ZVYZGiM3/P0AwDD46YsRMxvUWSSw5fDX1xbGJNrD708QSPTy Uy6coBIhhcmFX8TJw9PU86mt143ll+c/1zmu23WSyIM/US9tYjMbGYC0qhVG1Qbq O7tbIBWJnwoXmwKSbx5R3xEnKMWzIvYcnp6OVvv+OnlKK7FnA4lBORG7qrewBhgi 5oUpifX2QWx6PGpHsmBpznzg8NAOouAFoY46z/tvZQeRwq2mo6haLW+M95BpttGd JYM03mAud1IBnf2BNGaJT25euAcsLI6Io2CGaQi2qXd2s26anhaoEXxzHoJbYoGp /QCSCvgjM/yMmqJnC4c7gAglus1WrzVEiMGzoq44KeMPqgcgMBHZRKVV79/x06Ai FZJUawHiJs/2LKqGH9IpwQEjWiCbzmX3Hhkh+KR+uEiZ77z0oBhFfsROCUi6vDmH AlkND/7R81au8Gy7vOJY/9ECJ4xtJzKlrPe4sI4XJPj6Kunhq9x6HKjpLtioM4Vg 3jd1rHviIXUIvQgIc7JNPUPG5F0UbMF88kPxeTLWZ/7uVQeatQ2fGq0v5qiaQkKd F/Ca6mJQiU/aCCHjeIEmRwkA7Ib/h5Ixee48XSxRoLvMqrLMkuo= =tcyR -----END PGP SIGNATURE----- Merge tag 'arm-soc/for-6.14/devicetree-arm64' of https://github.com/Broadcom/stblinux into soc/dt This pull request contains Broadcom ARM64-based SoCs Device Tree updates for 6.14: - Dave adds the display pipeline DT nodes on BCM2712 (Raspberry Pi 5) - Rob removes some undocumented properties - Same ensures that the CFE stub area is reserved to allow secondary CPUs to be successfully brought up in Linux, also making sure that the address used in the spin table is also carved out.

MediaTek ARM64 DeviceTree updates for v6.14
This adds a few cleanups, enhances support for upstreamed SoCs
and machines, other than adding new ones.
In particular, fixes and improvements:
- MT8516 gets a few fixes for GICv2, Watchdog and I2C, and
support for the Keypad controller;
- MT8390 Genio 700 board gets basic audio support;
- MT8365 gets an alias for its integrated ethernet controller;
- MT8195 gets an important fix for system suspend: all of the
machines based on this SoC and its IoT variant can now
properly perform PM Suspend to RAM;
- MT8188 gets support for its Mali GPU with DVFS and a fix for
the OVL Hardware found in the Display Controller using the
right compatible strings;
- MT8186 Chromebooks can now suspend properly thanks to a fix
moving the USB wakeups from XHCI to MTU3 (USB) controller;
- MT8183 Chromebooks get a fix for their DMIC microphone and
proper support for their second-source touchscreen;
- MT7988 SoC and the BananaPi R4 board gets support for Pinctrl,
eMMC/SD, Thermal, CPU DVFS, PCI-Express, and peripherals like
the RT5190A PMIC, PCA9545 I2C mux, and others;
- MT7986 BananaPi R3 board gets support for SATA power socket;
And cleanups:
- Dropped regulator-compatible property from MediaTek DTs;
- Aligned thermal node names with bindings on MT8183 Kukui;
- MT6397 PMIC get proper sub-node names, fixing dt validation;
- The property enabling Wake-On-Lan feature changed in all of
the boards and driver to match the actual meaning of it
(mediatek,mac-wol now enables wol on mac instead of phy);
- Compatibles for MediaTek PMIC Keypad are added to bindings
and can now pass dts validation;
...and the newly added machines are:
- MT8188 (Ciri) Lenovo Chromebook Duet
- MT8186 (Starmie) ASUS Chromebook Enterprise CM30
- MT8186 (Chinchou) ASUS Chromebook CZ12 and CZ12 Flip

Minor improvements in ARM64 DTS for v6.14
1. Spreadtrum:
- Correct few issues pointed out by DT schema around properties and
node names.
- Move fuel-gauge from DTSI to DTS, because it belongs to the board.
- Use undeprecated properties, like battery-detect-gpios, already
supported by Linux.
2. Uniphier: Use un-deprecated hp-det-gpios (no ABI impact expected).

Minor improvements in ARM64 DTS for v6.14
1. Spreadtrum:
- Correct few issues pointed out by DT schema around properties and
node names.
- Move fuel-gauge from DTSI to DTS, because it belongs to the board.
- Use undeprecated properties, like battery-detect-gpios, already
supported by Linux.
2. Uniphier: Use un-deprecated hp-det-gpios (no ABI impact expected).

1. Clear LLBCTL if secondary mmu mapping changed. 2. Add hypercall service support for usermode VMM. This is a really small changeset, because the Chinese New Year (Spring Festival) is coming.
