[Bug 1441876] Re: arm64 efi stub support
I've verified that I can successfully boot a trusty cloud image in an
EFI VM by upgrading it to proposed and manually adding console=ttyAMA0
to the kernel commandline (a separate issue):

Title:
arm64 efi stub support
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Trusty:
Fix Committed
Bug description:
[Impact]
ARM64 systems that use UEFI cannot boot the Ubuntu 3.13 kernel shipped in 14.04. This is significant because the only LTS cloud images Ubuntu provides for ARM64/UEFI include this kernel.
[Test Case]
Attempt to boot a 14.04 arm64-efi cloud image in QEMU as described here:
https://wiki.ubuntu.com/ARM64/QEMU
GRUB will fail, reporting that there is no EFI stub in the kernel.
[Regression Risk]
The proposed backport has been reworked to not require any changes that impact x86, other than new macros/functions that will not be used on x86. The biggest regression risk is therefore to other arm64 platforms that are currently supported by the 3.13 kernel. Luckily this list is small and can be tested.
