[patch v2 0/3] arm: pmu: support pmu/perf on OMAP4

Hi,

This patches support pmu irq routed from CTI, such as implemented
on OMAP4:

      - introduce some CTI helpers and registers' definition
      - introduce .enable_irq and .disable_irq into platform_data,
	so perf irq handler can handle irq correctly if it is
	routed from CTI on OMAP4
      - configure CTI on OMAP4 so that perf can work on OMAP4

The patches have been tested Ok on Pandaboard, and 'perf' does work
after applying them.

v2:
	- move cti related code out of perf_event.c
	- introduce .enable_irq and .disable_irq into platform_data
	as suggested by Will.

v1:
       - rebase the patch set against 2.6.38-rc6-next-20110301, fix
       conflicts, which is pointed out by Will Deacon
