cxl_dpa_perf'
In order to address the issue with being able to expose qos_class sysfs
attributes under 'ram' and 'pmem' sub-directories, the attributes must
be defined as static attributes rather than under driver->dev_groups.
To avoid implementing locking for accessing the 'struct cxl_dpa_perf`
lists, convert the list to a single 'struct cxl_dpa_perf' entry in
preparation to move the attributes to statically defined.
While theoretically a partition may have multiple qos_class via CDAT, this
has not been encountered with testing on available hardware. The code is
simplified for now to not support the complex case until a use case is
needed to support that.

Autodiscovered regions can fail to assemble if they are not discovered
in HPA decode order. The user will see failure messages like:
[] cxl region0: endpoint5: HPA order violation region1
[] cxl region0: endpoint5: failed to allocate region reference
The check that is causing the failure helps the CXL driver enforce
a CXL spec mandate that decoders be committed in HPA order. The
check is needless for autodiscovered regions since their decoders
are already programmed. Trying to enforce order in the assembly of
these regions is useless because they are assembled once all their
member endpoints arrive, and there is no guarantee on the order in
which endpoints are discovered during probe.
Keep the existing check, but for autodiscovered regions, allow the
out of order assembly after a sanity check that the lesser numbered
decoder has the lesser HPA starting address.

In preparation for adding a new caller of cxl_region_find_decoders()
teach it to find a decoder from a cxl_endpoint_decoder structure.
Combining switch and endpoint decoder lookup in one function prevents
code duplication in call sites.
Update the existing caller.

The compare function used to sort memblks into starting address
order fails when the result of its u64 address subtraction gets
truncated to an int upon return.
The impact of the bad sort is that memblks will be filled out
incorrectly. Depending on the set of memblks, a user may see no
errors at all but still have a bad fill, or see messages reporting
a node overlap that leads to numa init failure:
[] node 0 [mem: ] overlaps with node 1 [mem: ]
[] No NUMA configuration found
Replace with a comparison that can only result in: 1, 0, -1.

numa_fill_memblks() fills in the gaps in numa_meminfo memblks over a
physical address range. To do so, it first creates a list of existing
memblks that overlap that address range. The issue is that it is off
by one when comparing to the end of the address range, so memblks
that do not overlap are selected.
The impact of selecting a memblk that does not actually overlap is
that an existing memblk may be filled when the expected action is to
do nothing and return NUMA_NO_MEMBLK to the caller. The caller can
then add a new NUMA node and memblk.
Replace the broken open-coded search for address overlap with the
memblock helper memblock_addrs_overlap(). Update the kernel doc
and in code comments.

The SED Opal response parsing function response_parse() does not
handle the case of an empty atom in the response. This causes
the entry count to be too high and the response fails to be
parsed. Recognizing, but ignoring, empty atoms allows response
handling to succeed.

The TBA and TMA, along with an unused IB allocation, reside at low
addresses in the VM address space. A stray VM fault which hits these
pages must be serviced by making their page table entries invalid.
The scheduler depends upon these pages being resident and fails,
preventing a debugger from inspecting the failure state.
By relocating these pages above 47 bits in the VM address space they
can only be reached when bits [63:48] are set to 1. This makes it much
less likely for a misbehaving program to generate accesses to them.
The current placement at VA (PAGE_SIZE*2) is readily hit by a NULL
access with a small offset.
v2:
- Move it to the reserved space to avoid concflicts with Mesa
- Add macros to make reserved space management easier
v3:
- Move VM max PFN calculation into AMDGPU_VA_RESERVED macros

The NOKPROBE_SYMBOL macro (and others) were moved to
asm-generic/kprobes.h in 2017 by commit 7d134b2ce639 ("kprobes: move
kprobe declarations to asm-generic/kprobes.h"), and this new header
was included by asm/kprobes.h unconditionally on all architectures.
When kprobe support was added to parisc in 2017 by commit
8858ac8e9e9b1 ("parisc: Implement kprobes"), that header was only
included when CONFIG_KPROBES was enabled.
This can lead to build failures when NOKPROBE_SYMBOL is used, but
CONFIG_KPROBES is disabled. This mistake however was never actually
noticed because linux/kprobes.h also includes asm-generic/kprobes.h
(though I do not understand why that is, because it also includes
asm/kprobes.h).
To prevent eventual build failures, I suggest to always include
asm-generic/kprobes.h on parisc, just like all the other architectures
do. This way, including asm/kprobes.h suffices, and nobody (outside
of arch/) ever needs to explicitly include asm-generic/kprobes.h.

Pull KVM fixes from Paolo Bonzini:
"ARM:
- Avoid dropping the page refcount twice when freeing an unlinked
page-table subtree.
- Don't source the VFIO Kconfig twice
- Fix protected-mode locking order between kvm and vcpus
RISC-V:
- Fix steal-time related sparse warnings
x86:
- Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int"
- Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if
and only if the incoming events->nmi.pending is non-zero. If the
target vCPU is in the UNITIALIZED state, the spurious request will
result in KVM exiting to userspace, which in turn causes QEMU to
constantly acquire and release QEMU's global mutex, to the point
where the BSP is unable to make forward progress.
- Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl
being incorrectly truncated, and ultimately causes KVM to think a
fixed counter has already been disabled (KVM thinks the old value
is '0').
- Fix a stack leak in KVM_GET_MSRS where a failed MSR read from
userspace that is ultimately ignored due to ignore_msrs=true
doesn't zero the output as intended.
Selftests cleanups and fixes:
- Remove redundant newlines from error messages.
- Delete an unused variable in the AMX test (which causes build
failures when compiling with -Werror).
- Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails
with an error code other than ENOENT (a Hyper-V selftest bug
resulted in an EMFILE, and the test eventually got skipped).
- Fix TSC related bugs in several Hyper-V selftests.
- Fix a bug in the dirty ring logging test where a sem_post() could
be left pending across multiple runs, resulting in incorrect
synchronization between the main thread and the vCPU worker thread.
- Relax the dirty log split test's assertions on 4KiB mappings to fix
false positives due to the number of mappings for memslot 0 (used
for code and data that is NOT being dirty logged) changing, e.g.

Pull tracing fixes from Steven Rostedt:
- Fix the #ifndef that didn't have the 'CONFIG_' prefix on
HAVE_DYNAMIC_FTRACE_WITH_REGS
The fix to have dynamic trampolines work with x86 broke arm64 as the
config used in the #ifdef was HAVE_DYNAMIC_FTRACE_WITH_REGS and not
CONFIG_HAVE_DYNAMIC_FTRACE_WITH_REGS which removed the fix that the
previous fix was to fix.
- Fix tracing_on state
The code to test if "tracing_on" is set incorrectly used
ring_buffer_record_is_on() which returns false if the ring buffer
isn't able to be written to.
But the ring buffer disable has several bits that disable it. One is
internal disabling which is used for resizing and other modifications
of the ring buffer. But the "tracing_on" user space visible flag
should only report if tracing is actually on and not internally
disabled, as this can cause confusion as writing "1" when it is
disabled will not enable it.
Instead use ring_buffer_record_is_set_on() which shows the user space
visible settings.
- Fix a false positive kmemleak on saved cmdlines
Now that the saved_cmdlines structure is allocated via alloc_page()
and not via kmalloc() it has become invisible to kmemleak. The
allocation done to one of its pointers was flagged as a dangling
allocation leak. Make kmemleak aware of this allocation and free.
- Fix synthetic event dynamic strings
An update that cleaned up the synthetic event code removed the return
value of trace_string(), and had it return zero instead of the
length, causing dynamic strings in the synthetic event to always have
zero size.

clang-16 warns about casting between incompatible function types:
drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadow.c:161:10: error: cast from 'void (*)(const struct firmware *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
161 | .fini = (void(*)(void *))release_firmware,
This one was done to use the generic shadow_fw_release() function as a
callback for struct nvbios_source. Change it to use the same prototype
as the other five instances, with a trivial helper function that actually
calls release_firmware.

cdclk_compute_crawl_and_squash_midpoint()
cdclk_compute_crawl_and_squash_midpoint() was still assuming
that cd2x divider == 1 (ie. full divider == 2). Remove that
assumption by computing the dividers properly.
We'll also toss in a WARN in case the divider somehow ends
up different between the old and new cdclk configs. That should
never happen given we have div==2 in all the cdclk table entries
for the affected platforms.
If in the future we need a config where the divider also needs
to be changed then we likely need to add an extra step into the
cdclk programming sequence to make sure things stay within
legal limits throughout the process.
