[PATCH 0/4] EFI memmap fix v2

[Borislav Petkov <bp-Gina5bIWoIWzQB+pC5nmwQ@public.gmane.org>]

From: Borislav Petkov <bp-l3A5Bk7waGM@public.gmane.org>

Ok, here's v2 rebased and rediffed against tip (which has the relevant
efi branches).

Toshi, I'm pushing it to:

git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git#efi-fixes

so that you can give it another run and so that the build robot can poke
at it.

Thanks.

Changelog:

* v1:

this is the result of Toshi and me debugging a #GP on one of his big HP
boxes sporting UEFI. Each commit message should be self-explanatory so
please look there.

This has more or less an RFC nature thus I'm sending it now to collect
feedback. It is going to wait in the EFI queue anyway after the kexec
stuff gets sorted out first.

Comments and suggestions as always are very much appreciated.
