4140e2b31b tools headers: Synchronize prctl.h ABI header 
The prctl.h ABI header was slightly updated during the development of
the interface. In particular the "immutable" parameter became a bit in
the option argument.

Synchronize prctl.h ABI header again and make use of the definition in
the testsuite and "perf bench futex".

e48b92f9e1 tools headers: Synchronize linux/bits.h with the kernel sources 
To pick up the changes in this cset:

  0312e94abe ("treewide: fix typo 'unsigned __init128' -> 'unsigned __int128'")

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/include/linux/bits.h include/linux/bits.h

This required picking the const_true() define in linux/compiler.h as a
prep patch as that macro is used in the new linux/bits.h

Please see tools/include/uapi/README for further details.

Instead use the types already provided by the compiler.

Example issue with clang 19 for arm64:

(unsigned) long long/uint64_t as 128bit numbers are not supported.
Even libcs that do support 128bit numbers often fix intmax_t to 64bit
as it is used in ABIs and any change would break those.

8399f14666 tools/nolibc: add __nolibc_has_feature() 
Certain compiler features are signaled via the __has_feature()
preprocessor builtin.

Add a nolibc wrapper for it, similar to __nolibc_has_attribute().

60ccc16f53 tools/nolibc: drop manual stack pointer alignment 
The stack pointer is already aligned by the kernel to a multiple of 16.
See STACK_ROUND() in fs/binfmt_elf.c.

The manual realignment is unnecessary, drop it.

To pick up the changes in:

  2981557cb0 x86,kcfi: Fix EXPORT_SYMBOL vs kCFI

That required adding a copy of include/linux/cfi_types.h and its checking
in tools/perf/check-headers.h.

22f72088ff tools headers: Update the syscall table with the kernel sources

  2df1ad0d25 x86/arch_prctl: Simplify sys_arch_prctl()
  e632bca07c arm64: generate 64-bit syscall.tbl

This is basically to support the new open_tree_attr syscall.  But it
also needs to update asm-generic unistd.h header to get the new syscall
number.  And arm64 unistd.h header was converted to use the generic
64-bit header.
