Subject: [GIT PULL] EFI changes for v4.20

Greg,

Please pull the latest efi-core-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git efi-core-for-linus

   # HEAD: fa70f0d2ce96a892b38fbbaa60584af536f21f97 Merge tag 'efi-next' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi into efi/core

The main changes are:

 - 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
   we can more gracefully recover from buggy EFI firmware.

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

 - Other assorted fixes and updates.

 Thanks,

	Ingo
