It's been a while since the last shamu update. I did builds for the other devices and tested some things for shamu in the mean time. There's always something to do on one of the devices ;-)

Changelog:
-updated BFQ
-merged some ext4 patches from linux upstream
-merged some caf kgsl patches
-merged various other patches for several subsystems to improve battery life and efficiency
-added adreno idler
-prevent bcl driver to kick out cores in some cases
