[PATCH V2 0/4] perf, amd: Enable AMD family 15h northbridge counters

[Jacob Shin <jacob.shin@amd.com>]

The following patchset enables 4 additional performance counters in
AMD family 15h processors that counts northbridge events -- such as
number of DRAM accesses.

This patchset is based on top of previous work done by Robert Richter
<rric@kernel.org> :

https://lkml.org/lkml/2012/6/19/324

The main differences are:

- The northbridge counters are indexed contiguously right above the
  core performance counters.

- MSR address offset calculations are moved to architecture specific
  files.

- Interrups are set up to be delivered only to a single core.

V2:
Seprate out Robert's patches, and add properly ordered certificate of
origins.
