Cover letter [PATCH v3 00/13] arm64: stable UEFI mappings for kexec

Hi Ard,

Quoted 2 lines · Ard Biesheuvel

This is v3 of the series to update the UEFI memory map handling for the arm64 architecture so that:

I merged in your EFI patches into my master branch [1] and was able to do a successful chain of (four) kexec re-boots of the same kernel image on the ARM base model running LEG 14.10 EFI binaries [2]. EFI showed:

UEFI v2.40 (ARM Fixed Virtual Platform EFI Oct 23 2014 15:53:09, 0x00000000)

I only verified that all CPU's came up and that /proc/meminfo and the /proc/iomem 'System RAM' entries looked ok.
