[GIT PULL] EFI mixed mode support

[GIT PULL] EFI mixed mode support

[Matt Fleming]

Peter, I've got the mixed mode support in two branches.

'mixed-mode' is a clean topic branch against -rc3, which will generate
conflicts when you merge it with the EFI 'next' branch.

I performed the merge myself in 'mixed-mode-merged' so you can take a
look there to see how I resolved the conflicts.

If you want another option, just let me know.

The following changes since commit 6d0abeca3242a88cab8232e4acd7e2bf088f3bc2:
