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
