This series addresses the kexec/kdump crash on arm64 system with many CPUs
that was reported by Bhupesh.
Patches #1 and #2 fix the actual crash. Patches #3 and #4 optimize the
EFI persistent memreserve infrastructure so that fewer memblock reservations
are required.
Ard Biesheuvel (4):
arm64: memblock: don't permit memblock resizing until linear mapping
is up
efi/arm: defer persistent reservations until after paging_init()
efi: permit multiple entries in persistent memreserve data structure
efi: reduce the amount of memblock reservations for persistent
allocations
