 "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
     CPU

Pull s390 fixes from Heiko Carstens:

 - Add various missing READ_ONCE() to cmpxchg() loops prevent the
   compiler from potentially generating incorrect code. This includes a
   rather large change to the s390 specific hardware sampling code and
   its current use of cmpxchg_double().

   Do the fix now to get it out of the way of Peter Zijlstra's
   cmpxchg128() work, and have something that can be backported. The
   added new code includes a private 128 bit cmpxchg variant which will
   be removed again after Peter's rework is available. Also note that
   this 128 bit cmpxchg variant is used to implement 128 bit
   READ_ONCE(), while strictly speaking it wouldn't be necessary, and
   _READ_ONCE() should also be sufficient; even though it isn't obvious
   for all converted locations that this is the case. Therefore use this
   implementation for for the sake of clarity and consistency for now.

 - Fix ipl report address handling to avoid kdump failures/hangs.

 - Fix misuse of #(el)if in kernel decompressor.

 - Define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36,
   caused by the recently changed discard behaviour.

 - Make sure _edata and _end symbols are always page aligned.

 - The current header guard DEBUG_H in one of the s390 specific header
   files is too generic and conflicts with the ath9k wireless driver.
   Add an _ASM_S390_ prefix to the guard to make it unique.

 - Update defconfigs.

Pull nolibc fixes from Paul McKenney:

 - The fd_set structure was incorrectly defined as arrays of u32 instead
   of long, which breaks BE64. Fix courtesy of Sven Schnelle.

 - S_ISxxx macros were incorrectly testing the bits after applying them
   instead of bitwise ANDing S_FMT with the value. Fix from Warner Losh.

 - The mips code was randomly broken due to an unprotected "noreorder"
   directive in the _start code that could prevent the assembler from
   filling delayed slots. This in turn resulted in random other
   instructions being placed into those slots. Fix courtesy of Willy
   Tarreau.

 - The current nolibc header layout refrains from including files that
   are not explicitly included by the code using nolibc. Unfortunately,
   this causes build failures when such files contain definitions that
   are used (for example) by libgcc. Example definitions include raise()
   and memset(), which are called by some architectures, but only at
   certain optimization levels. Fix courtesy of Willy Tarreau.

 - gcc 11.3 in ARM thumb2 mode at -O2 recognized a memset() construction
   inside the memset() definition. The compiler replaced this
   construction with a call to... memset(). Userland cannot be forced to
   build with -ffreestanding, so an empty asm() statement was introduced
   into the loop the loop in order to prevent the compiler from making
   this unproductive transformation. Fix courtesy of Willy Tarreau.

 - Most of the O_* macros were wrong on RISCV because their octal values
   were coded as hexadecimal. This resulted in the getdents64() selftest
   failing. Fix courtesy of Willy Tarreau.

This was tested on x86_64, i386, armv5, armv7, thumb1, thumb2, mips and
riscv, all at -O0, -Os and -O3.

We are observing performance drop in many usecases which include
games, 3D benchmark applications,etc.. To solve this problem, We
are strictly not allowing top down flag enabled allocations to
steal the memory space from cpu visible region.

The idea is, we are sorting each order list entries in
ascending order and compare the last entry of each order
list in the freelist and return the max block.

This patch improves the 3D benchmark scores and solves
fragmentation issues.

Merge tag 'perf-tools-fixes-for-v6.2-2-2023-01-11' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Make 'perf kmem' cope with the removal of some
   kmem:kmem_cache_alloc_node and kmem:kmalloc_node in the
   11e9734b ("mm/slab_common: unify NUMA and UMA version of
   tracepoints") commit, making sure it works with Linux >= 6.2 as well
   as with older kernels where those tracepoints are present.

 - Also make it handle the new "node" kmem:kmalloc and
   kmem:kmem_cache_alloc tracepoint field introduced in that same
   commit.

 - Fix hardware tracing PMU address filter duplicate symbol selection,
   that was preventing to match with static functions with the same name
   present in different object files.

 - Fix regression on what linux/types.h file gets used to build the "BPF
   prologue" 'perf test' entry, the system one lacks the fmode_t
   definition used in this test, so provide that type in the test
   itself.

 - Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the
   user asks for linking with the libbpf package provided by the distro,
   then it has to be >= 0.8.0. Using the libbpf supplied with the kernel
   would be a fallback in that case.

 - Fix the build when libbpf isn't available or explicitly disabled via
   NO_LIBBPF=1.

 - Don't try to install libtraceevent plugins as its not anymore in the
   kernel sources and will thus always fail.

Use READ_ONCE() before cmpxchg() to prevent that the compiler generates

The current cmpxchg_double() loops within the perf hw sampling code do not
have READ_ONCE() semantics to read the old value from memory. This allows
the compiler to generate code which reads the "old" value several times
from memory, which again allows for inconsistencies.

For example:

        /* Reset trailer (using compare-double-and-swap) */
        do {
                te_flags = te->flags & ~SDB_TE_BUFFER_FULL_MASK;
                te_flags |= SDB_TE_ALERT_REQ_MASK;
        } while (!cmpxchg_double(&te->flags, &te->overflow,
                 te->flags, te->overflow,
                 te_flags, 0ULL));

The compiler could generate code where te->flags used within the
cmpxchg_double() call may be refetched from memory and which is not
necessarily identical to the previous read version which was used to
generate te_flags. Which in turn means that an incorrect update could
happen.

Fix this by adding READ_ONCE() semantics to all cmpxchg_double()
loops. Given that READ_ONCE() cannot generate code on s390 which atomically
reads 16 bytes, use a private compare-and-swap-double implementation to
achieve that.

Also replace cmpxchg_double() with the private implementation to be able to
re-use the old value within the loops.

As a side effect this converts the whole code to only use bit fields
to read and modify bits within the hws trailer header.

The newly added spi-cs-setup-ns doesn't really fit with the existing
property names for delays, rename it so that it does before it makes it
into a release and becomes ABI.

The two debug messages in spidev_open() dereference spidev->spi without
taking the lock and without checking if it's not null. This can lead to
a crash. Drop the messages as they're not needed - the user-space will
get informed about ENOMEM with the syscall return value.

There's a spinlock in place that is taken in file_operations callbacks
whenever we check if spidev->spi is still alive (not null). It's also
taken when spidev->spi is set to NULL in remove().

This however doesn't protect the code against driver unbind event while
one of the syscalls is still in progress. To that end we need a lock taken
continuously as long as we may still access spidev->spi. As both the file
ops and the remove callback are never called from interrupt context, we
can replace the spinlock with a mutex.
