[GIT pull] timer fixes for 3.15

[Thomas Gleixner]

Linus,

please pull the latest timers-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-urgent-for-linus

Two small fixlets for ARM SoC clocksource drivers:

* Avoid calling functions which might sleep from interrupt [disabled]
  context in tcb_clksrc used on Atmel SoCs.

* Use irq_force_affinity() to pin the per cpu timer interrupt on a not
  yet online cpu in the SiRFprimaII driver.

Thanks,

	tglx
