Subject: [GIT PULL 00/11] EFI updates for v4.20

Thomas, Ingo,

Please pull/cherry-pick the below. Note that the first three patches will
be depended upon by an irqchip series that Marc Zyngier has sent out last
week, and that targets the next release as well. So please advise how to
proceed with that: we could simply apply those patches first and use the
resulting commit in tip.git as a stable branch, I suppose, but I'll let
Marc chime in in case he has any other ideas.

Thanks,
Ard.

  x86: boot: Fix EFI stub alignment (2018-09-26 12:15:01 +0200)

----------------------------------------------------------------
EFI updates for v4.20:
- Add support for enlisting the help of the EFI firmware to create memory
  reservations that persist across kexec.
- Add page fault handling to the runtime services support code on x86 so

- Fix command line handling on x86 for the boot path that omits the stub's
  PE/COFF entry point.
- Other assorted fixes.
