Linus,

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
