e0f63bc68f drm/print: Include drm_device.h
The header drm_print.h uses members of struct drm_device pointers, as
such, it should include drm_device.h to let the compiler know the full
type definition.

Without such include, users of drm_print.h that don't explicitly need
drm_device.h would bump into build errors and be forced to include the
latter.

405057718a kgdb patches for 6.14
A very small set of changes this kernel cycle. It consists of two cleanups,
 one switches to kmap_local_page() (from kmap_atomic() ) and the other
 removes a bit of dead code.

Linus Torvalds
0f8e26b38d 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.

f0ef073e21 include/linux/lz4.h: add some missing macros
Currently, LZ4_DISTANCE_MAX and LZ4_DECOMPRESS_INPLACE_MARGIN are
defined in the erofs subsystem for LZ4 in-place decompression, which is
somewhat unsuitable since they should belong to the LZ4 itself and
may change with future LZ4 codebase updates.

Move them to include/linux/lz4.h to match the upstream LZ4 library [1].
No logic changes.

The bodies of __signed_type_use() and __unsigned_type_use() are much the
same size as their names - so put the bodies in the only line that expands
them.

Similarly __signed_type() is defined separately for 64bit and then used
exactly once just below.

Change the test for __signed_type from CONFIG_64BIT to one based on gcc
defined macros so that the code is valid if it gets used outside of a

495bba17cd minmax.h: simplify the variants of clamp()
Always pass a 'type' through to __clamp_once(), pass '__auto_type' from
clamp() itself.

The expansion of __types_ok3() is reasonable so it isn't worth the added
complexity of avoiding it when a fixed type is used for all three values.

c3939872ee minmax.h: move all the clamp() definitions after the min/max() ones
At some point the definitions for clamp() got added in the middle of the
ones for min() and max().  Re-order the definitions so they are more
sensibly grouped.

a5743f32ba minmax.h: use BUILD_BUG_ON_MSG() for the lo < hi test in clamp()
Use BUILD_BUG_ON_MSG(statically_true(ulo > uhi), ...) for the sanity check
of the bounds in clamp().  Gives better error coverage and one less
expansion of the arguments.

b280bb27a9 minmax.h: reduce the #define expansion of min(), max() and clamp()
Since the test for signed values being non-negative only relies on
__builtion_constant_p() (not is_constexpr()) it can use the 'ux' variable
instead of the caller supplied expression.  This means that the #define
parameters are only expanded twice.  Once in the code and once quoted in
the error message.

10666e9920 minmax.h: update some comments
- Change three to several.
- Remove the comment about retaining constant expressions, no longer true.
- Realign to nearer 80 columns and break on major punctiation.
- Add a leading comment to the block before __signed_type() and __is_nonneg()
  Otherwise the block explaining the cast is a bit 'floating'.
  Reword the rest of that comment to improve readability.

   allowed after that.
 
 - Drop obsolete UGA graphics code and switch to a more ergonomic API to
   traverse handle buffers. Simplify some error paths using a __free()
   helper while at it.
 
 - Fix some W=1 warnings when CONFIG_EFI=n
 
 - Rely on the dentry cache to keep track of the contents of the efivarfs
   filesystem, rather than using a separate linked list.
 
 - Improve and extend efivarfs test cases.
 
 - Synchronize efivarfs with underlying variable store on resume from
   hibernation - this is needed because the firmware itself or another OS
   running on the same machine may have modified it.
 
 - Fix x86 EFI stub build with GCC 15.
 
 - Fix kexec/x86 false positive warning in EFI memory attributes table
   sanity check.

f2ad904e92 soc: driver updates for 6.14
These are changes to SoC specific drivers and DT bindings that don't have
 a separate subsystem tree, or that get grouped here for simplicity.
 Nothing out of the ordinary for the 6.14 release here:
 
  - Most of the updates are for Qualcomm specific drivers, adding support
    for additional SoCs in the exssting drivers, and support for wrapped
    encryption key access in the SCM firmware.
 
  - The Arm SCMI firmware code gains support for having multiple
    instances of firmware running, and better module auto loading.
 
  - A few minor updates for litex, samsung, ti, tegra, mediatek, imx and
    renesas platforms.
 
  - Reset controller updates for amlogic, to add support for the A1 soc
    and clean up the existing code.
 
  - Memory controller updates for ti davinci aemif, refactoring the code
    and adding a few interfaces to other drivers.

Pull SoC driver updates from Arnd Bergmann:
 "These are changes to SoC specific drivers and DT bindings that don't
  have a separate subsystem tree, or that get grouped here for
  simplicity.

  Nothing out of the ordinary for the 6.14 release here:

   - Most of the updates are for Qualcomm specific drivers, adding
     support for additional SoCs in the exssting drivers, and support
     for wrapped encryption key access in the SCM firmware.

   - The Arm SCMI firmware code gains support for having multiple
     instances of firmware running, and better module auto loading.

   - A few minor updates for litex, samsung, ti, tegra, mediatek, imx
     and renesas platforms.

   - Reset controller updates for amlogic, to add support for the A1 soc
     and clean up the existing code.

   - Memory controller updates for ti davinci aemif, refactoring the
     code and adding a few interfaces to other drivers"

f102039270 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.

931656b9e2 kvm: defer huge page recovery vhost task to later
Some libraries want to ensure they are single threaded before forking,
so making the kernel's kvm huge page recovery process a vhost task of
the user process breaks those. The minijail library used by crosvm is
one such affected application.

Defer the task to after the first VM_RUN call, which occurs after the
parent process has forked all its jailed processes. This needs to happen
only once for the kvm instance, so introduce some general-purpose
infrastructure for that, too.  It's similar in concept to pthread_once;
except it is actually usable, because the callback takes a parameter.

e8744fbc83 tracing updates for v6.14:
- 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.
 
 - Update the Rust tracepoint code to use the C code too
 
   There was some duplication of the tracepoint code for Rust that did the
   same logic as the C code. Add a helper that makes it possible for both
   algorithms to use the same logic in one place.
 
 - Add poll to trace event hist files
 
   It is useful to know when an event is triggered, or even with some
   filtering. Since hist files of events get updated when active and the
   event is triggered, allow applications to poll the hist file and wake up
   when an event is triggered. This will let the application know that the
   event it is waiting for happened.
 
 - Add :mod: command to enable events for current or future modules
 
   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.
 
   Add the command where if ':mod:<module>' is written into set_event, then
   either all the modules events are enabled if it is loaded, or cache it so
   that the module's events are enabled when it is loaded. This also works
   from the kernel command line, where "trace_event=:mod:<module>", when the
   module is loaded at boot up, its events will be enabled then.

Merge tag 'fsnotify_hsm_for_v6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull fsnotify pre-content notification support from Jan Kara:
 "This introduces a new fsnotify event (FS_PRE_ACCESS) that gets
  generated before a file contents is accessed.

  The event is synchronous so if there is listener for this event, the
  kernel waits for reply. On success the execution continues as usual,
  on failure we propagate the error to userspace. This allows userspace
  to fill in file content on demand from slow storage. The context in
  which the events are generated has been picked so that we don't hold
  any locks and thus there's no risk of a deadlock for the userspace
  handler.

  The new pre-content event is available only for users with global
  CAP_SYS_ADMIN capability (similarly to other parts of fanotify
  functionality) and it is an administrator responsibility to make sure
  the userspace event handler doesn't do stupid stuff that can DoS the
  system.

  Based on your feedback from the last submission, fsnotify code has
  been improved and now file->f_mode encodes whether pre-content event
  needs to be generated for the file so the fast path when nobody wants
  pre-content event for the file just grows the additional file->f_mode
  check. As a bonus this also removes the checks whether the old
  FS_ACCESS event needs to be generated from the fast path. Also the
  place where the event is generated during page fault has been moved so
  now filemap_fault() generates the event if and only if there is no
  uptodate folio in the page cache.

  Also we have dropped FS_PRE_MODIFY event as current real-world users
  of the pre-content functionality don't really use it so let's start
  with the minimal useful feature set"

da6b353786 pwm: Ensure callbacks exist before calling them
If one of the waveform functions is called for a chip that only supports
.apply(), we want that an error code is returned and not a NULL pointer
exception.

53dac34539 hrtimers: Force migrate away hrtimers queued after CPUHP_AP_HRTIMERS_DYING
hrtimers are migrated away from the dying CPU to any online target at
the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers
handling tasks involved in the CPU hotplug forward progress.

However wakeups can still be performed by the outgoing CPU after
CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being
armed. Depending on several considerations (crystal ball power management
based election, earliest timer already enqueued, timer migration enabled or
not), the target may eventually be the current CPU even if offline. If that
happens, the timer is eventually ignored.

The most notable example is RCU which had to deal with each and every of
those wake-ups by deferring them to an online CPU, along with related
workarounds:

_ e787644caf (rcu: Defer RCU kthreads wakeup when CPU is dying)
_ 9139f93209 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU)
_ f7345ccc62 (rcu/nocb: Fix rcuog wake-up from offline softirq)

The problem isn't confined to RCU though as the stop machine kthread
(which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end
of its work through cpu_stop_signal_done() and performs a wake up that
eventually arms the deadline server timer:

   WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0
   CPU: 94 UID: 0 PID: 588 Comm: migration/94 Not tainted

     enqueue_task_fair
     enqueue_task
     ttwu_do_activate
     try_to_wake_up
     complete
     cpu_stopper_thread

Instead of providing yet another bandaid to work around the situation, fix
it in the hrtimers infrastructure instead: always migrate away a timer to
an online target whenever it is enqueued from an offline CPU.

This will also allow to revert all the above RCU disgraceful hacks.

fa3595523d io_uring: get rid of alloc cache init_once handling
init_once is called when an object doesn't come from the cache, and
hence needs initial clearing of certain members. While the whole
struct could get cleared by memset() in that case, a few of the cache
members are large enough that this may cause unnecessary overhead if
the caches used aren't large enough to satisfy the workload. For those
cases, some churn of kmalloc+kfree is to be expected.

Ensure that the 3 users that need clearing put the members they need
cleared at the start of the struct, and wrap the rest of the struct in
a struct group so the offset is known.

While at it, improve the interaction with KASAN such that when/if
KASAN writes to members inside the struct that should be retained over
caching, it won't trip over itself. For rw and net, the retaining of
the iovec over caching is disabled if KASAN is enabled. A helper will
free and clear those members in that case.

8259cb14a7 rv: Reset per-task monitors also for idle tasks
RV per-task monitors are implemented through a monitor structure
available for each task_struct. This structure is reset every time the
monitor is (re-)started, to avoid inconsistencies if the monitor was
activated previously.
To do so, we reset the monitor on all threads using the macro
for_each_process_thread. However, this macro excludes the idle tasks on
each CPU. Idle tasks could be considered tasks on their own right and it
should be up to the model whether to ignore them or not.

Reset monitors also on the idle tasks for each present CPU whenever we
reset all per-task monitors.

     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)

754916d4a2 capabilities patches for 6.14-rc1
This branch contains basically the same two patches as last time:
 
 1. A patch by Paul Moore to remove the cap_mmap_file() hook, as it simply
    returned the default return value and so doesn't need to exist.
 2. A patch by Jordan Rome to add a trace event for cap_capable(), updated
    to address your feedback during the last cycle.
 
 Both patches have been sitting in linux-next since 6.13-rc1 with no
 issues.
