Please pull my perf.git tree support

[Paul Mackerras <paulus@samba.org>]

Ben,

When you set up your next branch for commits to go in 2.6.36-rc1,
please do a pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/paulus/perf.git master

to get a series of commits that add support for hw_breakpoint events
on 64-bit POWER server processors in the perf_event subsystem.  This
consists of a commit from me that adds support for most integer
instructions to the emulate_step() function, a series from K. Prasad
that add the ppc64-specific hw_breakpoint code, and some small
commits from me that fix a few bugs that I found in testing.

There is one commit in there from K. Prasad that modifies the generic
hw_breakpoint code to add the ability to have an arch-specific
unregister hook for hw_breakpoints.  It has been acked by Frederic
Weisbecker.

Thanks,
Paul.
