Ok, it looks like the easy approach to bring this into 3.16 is to pick
the following commits (in this order):
eeb9db09f738 x86/efi: Move all workarounds to a separate file quirks.c
8562c99cdd30 efi/reboot: Add generic wrapper around EfiResetSystem()
0c5ed61adbdb efi/reboot: Allow powering off machines using EFI
44be28e9dd98 x86/reboot: Add EFI reboot quirk for ACPI Hardware Reduced flag
All of these are clean cherry-picks (except for the last one that
needs same really small context adjustment). If there's no objection,
I'll be sending this out for review shortly.
Cheers,
