These changes are the raw update to linux-4.4.6-rt14. Kernel sources
are taken from kernel.org, and rt patch from the rt wiki download page.
During the rebasing, the following patch collided:
Force tick interrupt and get rid of softirq magic(I70131fb85).
Collisions have been removed because its logic was found on the
source already.

The interrupt request from each group are connected to a parent -interrupt controller, such as GIC in case of Exynos4210. - -The interrupt combiner controller consists of multiple combiners. Up to eight -interrupt sources can be connected to a combiner. The combiner outputs one -combined interrupt for its eight interrupt sources.

A combiner in the -interrupt controller module shares config/control registers with other -combiners.
