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

Using COHERENT_LINE_{MISS,HIT} for cache misses and references
respectively is completely wrong. Instead, use the L1D events which
are a better and more useful approximation despite ignoring instruction
traffic.

This patch updates the ARMv7 perf event numbers so that:

(1) A consistent naming scheme is used between different CPUs.

(2) Only events actually used by Linux are described.

(3) Where possible, architected events are used in preference to
    CPU-specific events.

This results in the removal of a load of unused, hardcoded data and
makes is more clear as to which events are supported on each PMU.

  To: linux-arm-kernel

Commit 8f622422 ("perf events: Add generic front-end and back-end
stalled cycle event definitions") added two new ABI events for counting
stalled cycles.

This patch adds support for these new events to the ARM perf
implementation.
