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.
