Hi Stephane,
Given the concerns expressed by Ingo, I have dropped the perfmon3 tree
from linux-next until they have been addressed. Hopefully that will not
be loo long. Let us all know how we can help with this.

Thanks, we'll try to finish the review ASAP (today+tomorrow) so that
it can be added back in 1-2 days. And it's sensible to keep it in the
separate perfmon3 tree as well (as long as it's not rebased) - that's
a convenient initial structure for new features.
( and the powerpc bits would be nice as well, they seem to be missing
from the current lineup - the more architectures keep hitting on
that code, the better the end result. )

I think I am missing something about rebasing. Are you saying you want
the patches to stay with the same tree until it is reviewed thoroughly? So
far I have used Linus' v2.6.28-rcXX tree as it evolves at a pace I can follow.
Is that okay?

The fully featured perfmon3 code (available as a branch of my kernel.org tree)
has all the architectures we currently support. There is some overlap with the
patchset posted on LKML. I focused on x86 because this is the key architecture
with a lot of demands. It should not be very difficult to derive the
powerpc patchset
from the fully featured git branch, same goes for MIPS, and SPARC. IA-64 will be
a bit more challenging because they already have a much older version
of perfmon2.
Switching IA-64 to perfmon3 now, would cause lots of perfmon2 features
to disappear
(e.g., sampling, system-wide).

Thanks for your help. I am fine going through the review process once again.
I am just hoping we can still make the 2.6.29 target.
