I'll be sending pull-requests to Florian soon, but I would like to get
my trees included in linux-next to get increased testing coverage of
them against everything else going on for 4.5. I'm expecting to produce
trees under these branch names for the forseeable future.

The irqchip's register area includes the the setup for the timer's
scaling factors, and for the platform we want a fixed configuration of
these registers.

fixed and a minor style cleanup to #2.
Patches 3, 4 are new, but trivial.
Andrea Merello (3):
irqchip: bcm2836: Add SMP support for the 2836
irqchip: bcm2836: tolerate IRQs while no flag is set in ISR
irqchip: bcm2836: make code more readable
Eric Anholt (1):
irqchip: bcm2836: Fix
