| Miscellaenous fixes for perf and 24x7 counters in powerpc.

| Patches 1,3,4 were submitted earlier as a part of the parametrized

| 
| Patch 2 simplifies and fixes a bug in catalog_read() which causes the
| catalog file to not read first page.

| Changelog[v3]
| 	[Michael Ellerman] Cleanup patches 1 and 2 and fix a bug
| 	Add patch 5/5 to update contact info for 24x7 and GPCI counters
| 
| Changelog[v2]
| 	Rebase to perf/core tree.
| 
| Cody P Schafer (3):
|   powerpc/perf/hv-24x7: use kmem_cache instead of aligned stack
|     allocations
|   perf Documentation: sysfs events/ interfaces
|   perf Documentation: remove duplicated docs for powerpc cpu specific
|     events

Per Michael Ellerman's suggestion, attaching an informal test case to
demonstrate the bug and the fix.
