[PATCH 0/4] EFI 1:1 mapping

[Borislav Petkov <bp@alien8.de>]

From: Borislav Petkov <bp@suse.de>

Hi all,

this one is 64-bit only for now and it has been tested only in kvm with
OVMF.

Keeping in mind the ihnerent efi b0rkedness left and right, I'd like to
be very cautious and conservative with this and not hurry anything until
it has been actually very well tested on a variety of baremetal boxes.

Please take a closer look and let me know.

Thanks.

  x86, cpa: Map in an arbitrary pgd
  x86, efi: Add an efi= kernel command line parameter
