[perfmon2] perfmon2 in 2.6.28-rc6 is broken on Power6

[Corey A. <cja...@li...>]

I want to report that perfmon2 in 2.6.28-rc6 is broken somehow on 
Power6, and possibly all Power-based machines.

Today, I tried booting Stephane's 2.6.28-rc6 perfmon2 kernel with 
perfmon2 enabled, and it hangs during the boot-up process right after 
outputting the line "INIT: version 2.86 booting"

Without perfmon2 enabled, it boots up fine.

So something has regressed, and I'm not sure what.  I will see if I can 
find the culprit and submit a patch.

Regards,

- Corey
