[GIT PULL] EFI ARM Xen support

[Matt Fleming]

Folks,

Please pull the following branch which contains support for Xen on ARM
EFI platforms.

This merge includes a merge of Stefano's xen/linux-next branch to pull
in the prerequisites required for Shannon's commit:

  11ee5491e5ff ("Xen: EFI: Parse DT parameters for Xen specific UEFI")

as it needs both the latest changes in the EFI 'next' branch (now
tip/efi/core) and xen/linux-next.

I have intentionally not included the individual patches as I would
normally do in a pull request, so that commit history created by my
merging of Stefano's branch is preserved, and so that there's no way
to accidentally apply the patches individually.

The following changes since commit 6c5450ef66816216e574885cf8d3ddb31ef77428:

  efivarfs: Make efivarfs_file_ioctl() static (2016-05-07 07:06:13 +0200)

are available in the git repository at:
