[patch v1 0/3] arm: support pmu irq routed from CTI

[tom.leiming at gmail.com]

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.

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