Merge tag 'x86_fpu_for_v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 FPU updates from Borislav Petkov:
"x86 fpu usage optimization and cleanups:
- make 64-bit kernel code which uses 387 insns request a x87 init
(FNINIT) explicitly when using the FPU
- misc cleanups"
* tag 'x86_fpu_for_v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/fpu/xstate: Use sizeof() instead of a constant
x86/fpu/64: Don't FNINIT in kernel_fpu_begin()
x86/fpu: Make the EFI FPU calling convention explicit
