[PATCH 0/3] powerpc: Instrument Hypervisor Calls

[Mike Kravetz]

Here is an updated version of the hcall instrumentation patches.
Unfortunately, I have not been able to spend as much time as I
would like on this (and it seems that will continue).  

This version addresses all comments received except Arnd's issue
with an #ifdef for each function in the assembly file.  I like
Jimi's suggestion for creating macros(which could also minimize
the #ifdefs), but have not got around to implementing this.
Suggestions of others way to accomplish this are welcome.

Statistic files are moved to debugfs, and remain split out by CPU.
After some thought, disable/enable of preemption was added around
the statistic gathering(mostly for timing).
