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
