Merge tag 'x86-fpu-2024-09-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fpu updates from Thomas Gleixner:
"Provide FPU buffer layout in core dumps:
Debuggers have guess the FPU buffer layout in core dumps, which is
error prone. This is because AMD and Intel layouts differ.
To avoid buggy heuristics add a ELF section which describes the buffer
layout which can be retrieved by tools"

x86/elf: Add a new FPU buffer layout info to x86 core files
