Subject: [PATCH 0/3] arm: support pmu irq routed from CTI

Hi,

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

	- introduce some CTI helpers and registers' definition
	- introduce platform_data to pmu driver, so perf irq handler
	can handle irq correctly if it is routed from CTI
	- 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.
