[kan . liang]

From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

The patches are to clean up different features. They all touch the
initialization code. There are some dependencies. So I put them in
a patch set to facilitate the review and merge.

Patch 1 is to clear up the PEBS-via-PT on hybrid.
The original V1 patch can be found at

This is the V2, which only update the comments.

Patch 2 is to clean up the 023H enumeration.
