  x86/pkey: Fix undefined behaviour with PKRU_WD_BIT (2021-12-19 22:44:34 +0100)

----------------------------------------------------------------
- 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
