#     Merge tag 'x86_urgent_for_v6.2_rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Borislav Petkov:
#     
#      - Make sure the poking PGD is pinned for Xen PV as it requires it this
#        way
#     
#      - Fixes for two resctrl races when moving a task or creating a new
#        monitoring group
#     
#      - Fix SEV-SNP guests running under HyperV where MTRRs are disabled to
#        not return a UC- type mapping type on memremap() and thus cause a
#        serious slowdown
#     
#      - Fix insn mnemonics in bioscall.S now that binutils is starting to fix
#        confusing insn suffixes
