If you are applying Matt's patch https://lkml.org/lkml/diff/2014/10/7/390/1 which
had been created 1 year ago to mainline vanilla kernel (Linux 4.3-rc4), you are not
able to direct patch in due to the Makefile error below:

~/MyWorks/linux_mainline$ git apply .git/rebase-apply/0001 --reject 
Checking patch arch/x86/kernel/reboot.c...
Hunk #1 succeeded at 527 (offset 11 lines).

You should resolve the Makefile error and then git add 5 files below:
- arch/x86/kernel/reboot.c
- drivers/firmware/efi/Makefile
- drivers/firmware/efi/reboot.c
- include/linux/efi.h
- drivers/firmware/efi/capsule.c

then you are able to patch in my patchset.

Already got agreement with Matt that Quark Security Header patch will not
be upstream to mainline as it is not a standard header. So Intel will carry this
patch ourselves.
