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,
