Subject: [PATCH 0/4] arm/efi: fix memblock reallocation crash due to
 persistent reservations
Message-ID: <20181106113732.16351-1-ard.biesheuvel@linaro.org>

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
