[PATCH 0/6] efi: Pass secure boot mode to kernel [ver #2]

From: David Howells
Date: Tue Nov 22 2016 - 19:24:50 EST



Here's a set of patches that can determine the secure boot state of the
UEFI BIOS and pass that along to the main kernel image. This involves
generalising ARM's efi_get_secureboot() function and making it mixed-mode
safe.

The patches can be found here also:

http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=efi-secure-boot

at tag:

efi-secure-boot-20161123

Note that the patches are not terminal on the branch.
