kexec/kdump: make struct crash_mem available without CONFIG_CRASH_DUMP
struct crash_mem defined under include/linux/crash_core.h represents a list of memory ranges. While it is used to represent memory ranges for kdump kernel, it can also be used for other kind of memory ranges. In fact, KEXEC_FILE_LOAD syscall in powerpc uses this structure to represent reserved memory ranges and exclude memory ranges needed to find the right memory regions to load kexec kernel. So, make the definition of crash_mem structure available for !CONFIG_CRASH_DUMP case too.

powerpc: Handle error in mark_rodata_ro() and mark_initmem_nx()
mark_rodata_ro() and mark_initmem_nx() use functions that can fail like set_memory_nx() and set_memory_ro(), leading to a not protected kernel. In case of failure, panic.

timer/migration: Remove buggy early return on deactivation
When a CPU enters into idle and deactivates itself from the timer
migration hierarchy without any global timer of its own to propagate,
the group event of that CPU is set to "ignore" and tmigr_update_events()
accordingly performs an early return without considering timers queued
by other CPUs.
If the hierarchy has a single level, and the CPU is the last one to
enter idle, it will ignore others' global timers, as in the following
layout:
[GRP0:0]
migrator = 0
active = 0
nextevt = T0i
/ \
0 1
active (T0i) idle (T1)
0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
[GRP0:0]
migrator = NONE
active = NONE
nextevt = T0i
/ \
0 1
idle (T0i) idle (T1)
1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1 and CPU 0 goes to idle with T1
unhandled.
This isn't proper to single level hierarchy though. A similar issue,
although slightly different, may arise on multi-level:
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T0:0i, T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = 0 migrator = NONE
active = 0 active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
active idle idle idle
0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
CPU 2 also has a timer. The expiry order is T0 (ignored) < T1 < T2
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T0:0i, T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = NONE migrator = NONE
active = NONE active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
idle idle idle idle
1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1. The change only propagated up to 1st
level so far.
[GRP1:0]
migrator = NONE
active = NONE
nextevt = T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = NONE migrator = NONE
active = NONE active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
idle idle idle idle
2) The change now propagates up to the top. tmigr_update_events() finds
that the child event is ignored and thus removes it. The top level next
event is now T2 which is returned to CPU 0 as its next effective expiry
to take account for as the global idle migrator. However T1 has been
ignored along the way, leaving it unhandled.
Fix those issues with removing the buggy related early return. Ignored
child events must not prevent from evaluating the other events within
the same group.

Merge tag 'cxl-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

This is clear from the stack trace, we call nfs4_ff_layout_prepare_ds()
which could error out initializing the mirror_ds, and then we go to
clean it all up and our check is only for if (!mirror->mirror_ds). This
is inconsistent with the rest of the users of mirror_ds, which have
if (IS_ERR_OR_NULL(mirror_ds))
to keep from tripping over this exact scenario. Fix this up in
ff_layout_cancel_io() to make sure we don't panic when we get an error.
I also spot checked all the other instances of checking mirror_ds and we
appear to be doing the correct checks everywhere, only unconditionally
dereferencing mirror_ds when we know it would be valid.

io_uring/net: ensure async prep handlers always initialize ->done_io
If we get a request with IOSQE_ASYNC set, then we first run the prep
async handlers. But if we then fail setting it up and want to post
a CQE with -EINVAL, we use ->done_io. This was previously guarded with
REQ_F_PARTIAL_IO, and the normal setup handlers do set it up before any
potential errors, but we need to cover the async setup too.

drm/nouveau/dp: Fix incorrect return code in r535_dp_aux_xfer()
I've recently been seeing some unexplained GSP errors on my RTX 6000 from
failed aux transactions:
[ 132.915867] nouveau 0000:1f:00.0: gsp: cli:0xc1d00002 obj:0x00730000
ctrl cmd:0x00731341 failed: 0x0000ffff
While the cause of these is not yet clear, these messages made me notice
that the aux transactions causing these transactions were succeeding - not
failing. As it turns out, this is because we're currently not returning the
correct variable when r535_dp_aux_xfer() hits an error - causing us to
never propagate GSP errors for failed aux transactions to userspace.
So, let's fix that.

When a lock is waiting for a reply for a remote operation, and recovery interrupts this "waiters" state, the remote operation is voided by the recovery, and no reply will be processed. The lkb waiters state for the remote operation is forcibly reset/cleared, so that the lock operation can be restarted after recovery. Improve the comments describing this.

We know the request is either being removed, or already in the process of

will find it multiple times and prevent cancelation progress.
Remove the dead check in cancelation as well for the hash_node being

drm/xe: Allow VRAM BO allocations aligned to 64K
While today we are getting VRAM allocations aligned to 64K as the XE_VRAM_FLAGS_NEED64K flag could be set, we shouldn't only rely on that flag and we should also allow caller to specify required 64K alignment explicitly. Define new XE_BO_NEEDS_64K flag for that.

drm/xe: Mark VF accessible interrupt registers
Interrupt registers 1900xx are VF accessible but only until version 12.50 as on newer platforms VFs are using memory-based interrupts. To avoid complexity, we mark those registers with XE_REG_OPTION_VF unconditionally, as IRQ handling on newer VFs is different anyway.

VFIO updates for v6.9-rc1
- Add warning in unlikely case that device is not captured with
driver_override. (Kunwu Chan)
- Error handling improvements in mlx5-vfio-pci to detect firmware
tracking object error states, logging of firmware error syndrom,
and releasing of firmware resources in aborted migration sequence.
(Yishai Hadas)
- Correct an un-alphabetized VFIO MAINTAINERS entry.
(Alex Williamson)
- Make the mdev_bus_type const and also make the class struct const
for a couple of the vfio-mdev sample drivers. (Ricardo B. Marliere)
- Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
Grace-Hopper superchip. During initialization of the chip-to-chip
interconnect in this hardware module, the PCI BARs of the device
become unused in favor of a faster, coherent mechanism for exposing
device memory. This driver primarily changes the VFIO
representation of the device to masquerade this coherent aperture
to replace the physical PCI BARs for userspace drivers. This also
incorporates use of a new vma flag allowing KVM to use write
combining attributes for uncached device memory. (Ankit Agrawal)
- Reset fixes and cleanups for the pds-vfio-pci driver. Save and
restore files were previously leaked if the device didn't pass
through an error state, this is resolved and later re-fixed to
prevent access to the now freed files. Reset handling is also
refactored to remove the complicated deferred reset mechanism.
(Brett Creeley)
- Remove some references to pl330 in the vfio-platform amba
driver. (Geert Uytterhoeven)
- Remove twice redundant and ugly code to unpin incidental pins
of the zero-page. (Alex Williamson)
- Deferred reset logic is also removed from the hisi-acc-vfio-pci
driver as a simplification. (Shameer Kolothum)
- Enforce that mlx5-vfio-pci devices must support PRE_COPY and
remove resulting unnecessary code. There is no device firmware
that has been available publicly without this support.
(Yishai Hadas)
- Switch over to using the .remove_new callback for vfio-platform
in support of the broader transition for a void remove function.
(Uwe Kleine-König)
- Resolve multiple issues in interrupt code for VFIO bus drivers
that allow calling eventfd_signal() on a NULL context. This
also remove a potential race in INTx setup on certain hardware
for vfio-pci, races with various mechanisms to mask INTx, and
leaked virqfds in vfio-platform. (Alex Williamson)

S390:
* Changes to FPU handling came in via the main s390 pull request
* Only deliver to the guest the SCLP events that userspace has
requested.
* More virtual vs physical address fixes (only a cleanup since
virtual and physical address spaces are currently the same).
* Fix selftests undefined behavior.
x86:
* Fix a restriction that the guest can't program a PMU event whose
encoding matches an architectural event that isn't included in the
guest CPUID. The enumeration of an architectural event only says
that if a CPU supports an architectural event, then the event can be
programmed *using the architectural encoding*. The enumeration does
NOT say anything about the encoding when the CPU doesn't report support
the event *in general*. It might support it, and it might support it
using the same encoding that made it into the architectural PMU spec.
* Fix a variety of bugs in KVM's emulation of RDPMC (more details on
individual commits) and add a selftest to verify KVM correctly emulates
RDMPC, counter availability, and a variety of other PMC-related
behaviors that depend on guest CPUID and therefore are easier to
validate with selftests than with custom guests (aka kvm-unit-tests).
* Zero out PMU state on AMD if the virtual PMU is disabled, it does not
cause any bug but it wastes time in various cases where KVM would check
if a PMC event needs to be synthesized.
* Optimize triggering of emulated events, with a nice ~10% performance
improvement in VM-Exit microbenchmarks when a vPMU is exposed to the
guest.
* Tighten the check for "PMI in guest" to reduce false positives if an NMI
arrives in the host while KVM is handling an IRQ VM-Exit.
* Fix a bug where KVM would report stale/bogus exit qualification information
when exiting to userspace with an internal error exit code.
* Add a VMX flag in /proc/cpuinfo to report 5-level EPT support.
* Rework TDP MMU root unload, free, and alloc to run with mmu_lock held for
read, e.g. to avoid serializing vCPUs when userspace deletes a memslot.
* Tear down TDP MMU page tables at 4KiB granularity (used to be 1GiB). KVM
doesn't support yielding in the middle of processing a zap, and 1GiB
granularity resulted in multi-millisecond lags that are quite impolite
for CONFIG_PREEMPT kernels.
* Allocate write-tracking metadata on-demand to avoid the memory overhead when
a kernel is built with i915 virtualization support but the workloads use
neither shadow paging nor i915 virtualization.
* Explicitly initialize a variety of on-stack variables in the emulator that
triggered KMSAN false positives.
* Fix the debugregs ABI for 32-bit KVM.
* Rework the "force immediate exit" code so that vendor code ultimately decides
how and when to force the exit, which allowed some optimization for both
Intel and AMD.
* Fix a long-standing bug where kvm_has_noapic_vcpu could be left elevated if
vCPU creation ultimately failed, causing extra unnecessary work.
* Cleanup the logic for checking if the currently loaded vCPU is in-kernel.
* Harden against underflowing the active mmu_notifier invalidation
count, so that "bad" invalidations (usually due to bugs elsehwere in the
kernel) are detected earlier and are less likely to hang the kernel.
x86 Xen emulation:
* Overlay pages can now be cached based on host virtual address,
instead of guest physical addresses. This removes the need to
reconfigure and invalidate the cache if the guest changes the
gpa but the underlying host virtual address remains the same.
* When possible, use a single host TSC value when computing the deadline for
Xen timers in order to improve the accuracy of the timer emulation.
* Inject pending upcall events when the vCPU software-enables its APIC to fix
a bug where an upcall can be lost (and to follow Xen's behavior).
* Fall back to the slow path instead of warning if "fast" IRQ delivery of Xen
events fails, e.g. if the guest has aliased xAPIC IDs.
RISC-V:
* Support exception and interrupt handling in selftests
* New self test for RISC-V architectural timer (Sstc extension)
* New extension support (Ztso, Zacas)
* Support userspace emulation of random number seed CSRs.
ARM:
* Infrastructure for building KVM's trap configuration based on the
architectural features (or lack thereof) advertised in the VM's ID
registers
* Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
x86's WC) at stage-2, improving the performance of interacting with
assigned devices that can tolerate it
* Conversion of KVM's representation of LPIs to an xarray, utilized to
address serialization some of the serialization on the LPI injection
path
* Support for _architectural_ VHE-only systems, advertised through the
absence of FEAT_E2H0 in the CPU's ID register
* Miscellaneous cleanups, fixes, and spelling corrections to KVM and
selftests
LoongArch:
* Set reserved bits as zero in CPUCFG.
* Start SW timer only when vcpu is blocking.
* Do not restart SW timer when it is expired.
* Remove unnecessary CSR register saving during enter guest.
* Misc cleanups and fixes as usual.
Generic:
* cleanup Kconfig by removing CONFIG_HAVE_KVM, which was basically always
true on all architectures except MIPS (where Kconfig determines the
available depending on CPU capabilities). It is replaced either by
an architecture-dependent symbol for MIPS, and IS_ENABLED(CONFIG_KVM)
everywhere else.
* Factor common "select" statements in common code instead of requiring
each architecture to specify it
* Remove thoroughly obsolete APIs from the uapi headers.
* Move architecture-dependent stuff to uapi/asm/kvm.h
* Always flush the async page fault workqueue when a work item is being
removed, especially during vCPU destruction, to ensure that there are no
workers running in KVM code when all references to KVM-the-module are gone,
i.e. to prevent a very unlikely use-after-free if kvm.ko is unloaded.
* Grab a reference to the VM's mm_struct in the async #PF worker itself instead
of gifting the worker a reference, so that there's no need to remember
to *conditionally* clean up after the worker.
Selftests:
* Reduce boilerplate especially when utilize selftest TAP infrastructure.
* Add basic smoke tests for SEV and SEV-ES, along with a pile of library
support for handling private/encrypted/protected memory.
* Fix benign bugs where tests neglect to close() guest_memfd files.

Devicetree updates for v6.9:
DT core:
- Add cleanup.h based auto release of struct device_node pointers via
__free marking and new for_each_child_of_node_scoped() iterator to use
it.
- Always create a base skeleton DT when CONFIG_OF is enabled. This
supports several usecases of adding DT data on non-DT booted systems.
- Move around some /reserved-memory code in preparation for further
improvements
- Add a stub for_each_property_of_node() for !OF
- Adjust the printk levels on some messages
- Fix __be32 sparse warning
- Drop RESERVEDMEM_OF_DECLARE usage from Freescale qbman driver
(currently orphaned)
- Add Saravana Kannan and drop Frank Rowand as DT maintainers
DT bindings:
- Convert Mediatek timer, Mediatek sysirq, fsl,imx6ul-tsc,
fsl,imx6ul-pinctrl, Atmel AIC, Atmel HLCDC, FPGA region, and
xlnx,sd-fec to DT schemas
- Add existing, but undocumented fsl,imx-anatop binding
- Add bunch of undocumented vendor prefixes used in compatible strings
- Drop obsolete brcm,bcm2835-pm-wdt binding
- Drop obsolete i2c.txt which as been replaced with schema in dtschema
- Add DPS310 device and sort trivial-devices.yaml
- Enable undocumented compatible checks on DT binding examples
- More QCom maintainer fixes/updates
- Updates to writing-schema.rst and DT submitting-patches.rst to cover
some frequent review comments
- Clean-up SPDX tags to use 'OR' rather than 'or'
