Pull x86 cpu updates from Borislav Petkov:
- Add helpers for WB{NO,}INVD with the purpose of using them in KVM and
thus diminish the number of invalidations needed. With preceding
cleanups, as always
* tag 'x86_core_for_v6.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/lib: Add WBINVD and WBNOINVD helpers to target multiple CPUs
x86/lib: Add WBNOINVD helper functions
x86/lib: Drop the unused return value from wbinvd_on_all_cpus()
drm/gpu: Remove dead checks on wbinvd_on_all_cpus()'s return value
