Indeed - and since it was the top commit I amended it, and while at it I
fixed not just the parenthesis error I introduced, but added the right
SHA1 as well:

efi/x86: Disallow efi=old_map in mixed mode

Before:

1f299fad1e31: ("efi/x86: Limit EFI old memory map to SGI UV machines")

enabling the old EFI memory map on mixed mode systems
disabled EFI runtime services altogether.

Sounds good!

Thanks,
