[PATCH 0/7] RFC: EFI stub for ARM

This RFC patch series adds EFI stub support for the ARM architecture.
Some code that was previously only used by x86/x86_64 is now shared
and has been made more general.  The stub for ARM is implemented in
a similar manner to x86 in that it is a shim layer between EFI and
the normal zImage/bzImage boot process, and that an image with the
stub configured is bootable as both a zImage and EFI application.

This patchset depends on a separately submitted bugfix to the
EFI stub: "correct call to free_pages"
