Hi folks,
I've got a patch accepted for the kernel to expose the size of the
underlying UEFI firmware for x86, and Ben's happy to take it for the
Debian kernel (#775191). I've written and tested a grub patch to match
(see http://blog.einval.com/2015/01/11#Jessie-EFI_5) which adds
support for this extra interface. Here it is. I'd appreciate it if we
can get this in for Jessie, and and of course it'd be lovely if this
went upstream too as it's generic.
There's another related patch for grub-installer to make sure that the
right grub packages get installed, too.

Subject: Add support for running a 64-bit Linux kernel on a 32-bit EFI
Some platforms might be capable of running a 64-bit Linux kernel but only
use a 32-bit EFI. To support such systems, it is necessary to work out the
size of the firmware rather than just the size of the kernel. To enable
that, there is now an extra EFI sysfs file to describe the underlying
firmware. Read that if possible, otherwise fall back to the kernel type
as before.

Changes:

.
[ Mathieu Trudel-Lapierre ]
* Fix overlap check in check_blocklists for load_env (backported patch
from upstream commit 1f6af2a9; LP: #1311247).
.
[ Steve McIntyre ]
* Add support for running a 64-bit Linux kernel on a 32-bit EFI (closes:
#775202).
.
[ Colin Watson ]
* Use mtmsr rather than mtmsrd in ppc64el-disable-vsx.patch, since the
"VSX Available" bit is in the lower half of the MSR anyway, and mtmsrd
faults on 32-bit systems (closes: #776400).
