scripts/gdb: add mm introspection utils
This command provides a way to traverse the entire page hierarchy by a
given virtual address on x86. In addition to qemu's commands info
tlb/info mem it provides the complete information about the paging
structure for an arbitrary virtual address. It supports 4KB/2MB/1GB and 5
level paging.
Here is an example output for 2MB success translation:

checkpatch: mark kunmap() and kunmap_atomic() deprecated
It was suggested by Fabio that kunmap() be marked deprecated in
checkpatch.[1] This did not seem necessary until an invalid conversion of
kmap_local_page() appeared in mainline.[2][3] The introduction of this bug
would have been flagged with kunmap() being marked deprecated.
Add kunmap() and kunmap_atomic() to checkpatch to help prevent further
confusion.

lib: add Dhrystone benchmark test
When working on SoC bring-up, (a full) userspace may not be available, making it hard to benchmark the CPU performance of the system under development. Still, one may want to have a rough idea of the (relative) performance of one or more CPU cores, especially when working on e.g. the clock driver that controls the CPU core clock(s). Hence make the classical Dhrystone 2.1 benchmark available as a Linux kernel test module, based on[1]. When built-in, this benchmark can be run without any userspace present. Parallel runs (run on multiple CPU cores) are supported, just kick the "run" file multiple times. Note that the actual figures depend on the configuration options that control compiler optimization (e.g. CONFIG_CC_OPTIMIZE_FOR_SIZE vs. CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE), and on the compiler options used when building the kernel in general. Hence numbers may differ from those obtained by running similar benchmarks in userspace.

include/linux/percpu_counter.h: race in uniprocessor percpu_counter_add()
The percpu interface is supposed to be preempt and irq safe. But: The uniprocessor implementation of percpu_counter_add() is not irq safe: if an interrupt happens during the +=, then the result is undefined. Therefore: switch from preempt_disable() to local_irq_save(). This prevents interrupts from interrupting the +=, and as a side effect prevents preemption.

error-injection: remove EI_ETYPE_NONE
Patch series "error-injection: Clarify the requirements of error
injectable functions".
Patches for clarifying the requirement of error injectable functions and
to remove the confusing EI_ETYPE_NONE.
This patch (of 2):
Since the EI_ETYPE_NONE is confusing type, replace it with appropriate
errno. The EI_ETYPE_NONE has been introduced for a dummy (error) value,
but it can mislead people that they can use ALLOW_ERROR_INJECTION(func,
NONE). So remove it from the EI_ETYPE and use appropriate errno instead.

memblock: always release pages to the buddy allocator in memblock_free_late()
If CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, memblock_free_pages()
only releases pages to the buddy allocator if they are not in the
deferred range. This is correct for free pages (as defined by
for_each_free_mem_pfn_range_in_zone()) because free pages in the
deferred range will be initialized and released as part of the deferred
init process. memblock_free_pages() is called by memblock_free_late(),
which is used to free reserved ranges after memblock_free_all() has
run. All pages in reserved ranges have been initialized at that point,
and accordingly, those pages are not touched by the deferred init
process. This means that currently, if the pages that
memblock_free_late() intends to release are in the deferred range, they
will never be released to the buddy allocator. They will forever be
reserved.
In addition, memblock_free_pages() calls kmsan_memblock_free_pages(),
which is also correct for free pages but is not correct for reserved
pages. KMSAN metadata for reserved pages is initialized by
kmsan_init_shadow(), which runs shortly before memblock_free_all().
For both of these reasons, memblock_free_pages() should only be called
for free pages, and memblock_free_late() should call __free_pages_core()
directly instead.
One case where this issue can occur in the wild is EFI boot on
x86_64. The x86 EFI code reserves all EFI boot services memory ranges
via memblock_reserve() and frees them later via memblock_free_late()
(efi_reserve_boot_services() and efi_free_boot_services(),
respectively). If any of those ranges happens to fall within the
deferred init range, the pages will not be released and that memory will
be unavailable.
For example, on an Amazon EC2 t3.micro VM (1 GB) booting via EFI:

"A fix for a regression that happened last week, rest is fixes that
will be headed to stable as well. In detail:
- Fix for a regression added with the leak fix from last week (me)
- In writing a test case for that leak, inadvertently discovered a
case where we a poll request can race. So fix that up and mark it
for stable, and also ensure that fdinfo covers both the poll tables
that we have. The latter was an oversight when the split poll table
were added (me)

The memcpy() of the data following a coreboot_table_entry couldn't be evaluated by the compiler under CONFIG_FORTIFY_SOURCE. To make it easier to reason about, add an explicit flexible array member to struct coreboot_device so the entire entry can be copied at once. Additionally, validate the sizes before copying.

lockref: stop doing cpu_relax in the cmpxchg loop
On the x86-64 architecture even a failing cmpxchg grants exclusive
access to the cacheline, making it preferable to retry the failed op
immediately instead of stalling with the pause instruction.
To illustrate the impact, below are benchmark results obtained by
running various will-it-scale tests on top of the 6.2-rc3 kernel and
Cascade Lake (2 sockets * 24 cores * 2 threads) CPU.
All results in ops/s. Note there is some variance in re-runs, but the
code is consistently faster when contention is present.

efi: tpm: Avoid READ_ONCE() for accessing the event log
Nathan reports that recent kernels built with LTO will crash when doing EFI boot using Fedora's GRUB and SHIM. The culprit turns out to be a misaligned load from the TPM event log, which is annotated with READ_ONCE(), and under LTO, this gets translated into a LDAR instruction which does not tolerate misaligned accesses. Interestingly, this does not happen when booting the same kernel straight from the UEFI shell, and so the fact that the event log may appear misaligned in memory may be caused by a bug in GRUB or SHIM. However, using READ_ONCE() to access firmware tables is slightly unusual in any case, and here, we only need to ensure that 'event' is not dereferenced again after it gets unmapped, but this is already taken care of by the implicit barrier() semantics of the early_memunmap() call.

Pull arm64 fixes from Will Deacon:
"Here's a sizeable batch of Friday the 13th arm64 fixes for -rc4. What
could possibly go wrong?
The obvious reason we have so much here is because of the holiday
season right after the merge window, but we've also brought back an
erratum workaround that was previously dropped at the last minute and
there's an MTE coredumping fix that strays outside of the arch/arm64
directory.
Summary:
- Fix PAGE_TABLE_CHECK failures on hugepage splitting path
- Fix PSCI encoding of MEM_PROTECT_RANGE function in UAPI header
- Fix NULL deref when accessing debugfs node if PSCI is not present
- Fix MTE core dumping when VMA list is being updated concurrently
- Fix SME signal frame handling when SVE is not implemented by the
