#     Merge tag 'x86_urgent_for_v5.16_rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 fixes from Borislav Petkov:
#     
#      - Prevent potential undefined behavior due to shifting pkey constants
#        into the sign bit
#     
#      - Move the EFI memory reservation code *after* the efi= cmdline parsing
#        has happened
#     
#      - Revert two commits which turned out to be the wrong direction to
#        chase when accommodating early memblock reservations consolidation
#        and command line parameters parsing
#
