[GIT PULL] EFI changes for arm64

[GIT PULL] EFI changes for arm64

[Matt Fleming]

Hi folks,

I pulled the arm64 EFI changes into the following topic branch. Catalin
was happy for this to go through tip, which definitely makes things
easier for the next merge window because of the dependency these patches
have on tip/x86/efi.

The following changes since commit e33655a386ed3b26ad36fb97a47ebb1c2ca1e928:

  efivars: Add compatibility code for compat tasks (2014-04-17 13:53:53 +0100)

Alternatively, I can merge the arm64-efi tree and wait for tip x86/efi
to go in before sending my pull request. Peter, Ingo, do you have any
preference?

Either way, I'd like to see this branch in -next to make sure there are
no (significant) conflicts before the merging window.

Thanks.

[GIT PULL] EFI changes for arm64

[Matt Fleming]

Catalin reports that the arm64 EFI changes in tip/arm64/efi are causing
boot issues when trying to run on a non-EFI machine. The below fix from
Leif skips the EFI code on such machines.

The following changes since commit 345c736edd07b657a8c48190baed2719b85d0938:

  efi/arm64: ignore dtb= when UEFI SecureBoot is enabled (2014-04-30 19:57:06 +0100)
