Subject[PATCH 0/6] MIPS: perf: Make perf work for 64-bit/Octeon counters.
Date
The existing MIPS perf hardware counter support only handles 32-bit
wide counters. Some CPUs (like Octeon) have the 64-bit wide variety.
This patch set allows perf to work on Octeon, and I hope not break
existing systems. I have not tested it on non-Octeon systems, so it
would be good if someone could test that.

Summary of the patches:

1) Fix faulty Octeon interrupt controller code.

2) Add some register definitions.

3,4) Clean up existing code.

5) 64-bit perf counter support.

6) Octeon perf event bindings.

Patch 4/6 is the biggest and has the highest chance of having broken
something.

This patch set depends on a couple of others that have previously been
sent to Ralf:
