Subject: [PATCH 0/3] EFI memmap fix

From: Borislav Petkov <bp@...e.de>

Hi guys,

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.

Thanks.

Borislav Petkov (3):
  x86, ptdump: Add the functionality to dump an arbitrary pagetable
  efi: Dump the EFI page table
  efi: Make efi virtual runtime map passing more robust
