[PATCH 0/3] Updates to ARM PMU event numbers

[Will Deacon]

Hello,

These three patches update the ARM PMU event numbers so that:

* The two new ABI events are supported on ARM (frontend/backend stalls).

* The ARMv7 PMU events are generally tidied up and made consistent
  between PMUs.

* The HW_CACHE events on Cortex-A9 are routed to more sane event
  definitions. I'd like to get this into the stable tress, so it exists
  as a separate patch.

Note that the generalised events are just an approximation, so although
we don't always provide a direct correspondence in hardware, we aim to
use an event that will at least exhibit statistically equivalent results.

These are taken again rmk/devel-stable, although the A9 fix will apply
against -rc8 and I plan to push it as a fix.

Feedback welcome,

Will
