This is a backport to v4.20 of the fix for an early memblock reserve issue
observed on arm64 systems with a GICv3 and many (i.e., hundreds of) CPUs.

Ard Biesheuvel (2):
  arm64, mm, efi: Account for GICv3 LPI tables in static memblock
    reserve table
  efi/arm: Revert "Defer persistent reservations until after
    paging_init()"
