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. The combined interrupt -is usually connected to a parent interrupt controller. - -A single node in the device tree is used to describe the interrupt combiner -controller module (which includes multiple combiners). A combiner in the -interrupt controller module shares config/control registers with other -combiners. For example, a 32-bit interrupt enable/disable config register -can accommodate up to 4 interrupt combiners (with each combiner supporting -up to 8 interrupt sources). - -Required properties: -- compatible: should be "samsung,exynos4210-combiner". -- interrupt-controller: Identifies the node as an interrupt controller. -- #interrupt-cells: should be <2>.
