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
