[PATCH v2 0/2] perf/x86: fixes and improvement for Intel Atom PEBS support

[Stephane Eranian <eranian@google.com>]

This short series fixes total breakage of Intel Atom PEBS support in recent kernels.
The problems were introduced with the changes in the PEBS logic to handle 
deeper buffer.

The first patch fixes PEBS and LBR problems, including NULL pointers, wrong pointer
arithmetic, and wrong pebs record layout assumption.

The second patch adds an alias for cycles:pp to Intel Atom given that perf record/top
uses cycles:pp nowadays.

In V2, we removed the alias function specific to Atom use use the one from Core2
because it is identical as suggested by Kan Liang.
