Here are a couple of patches for perf for hardware breakpoints. Along
with https://lkml.org/lkml/2012/8/16/5 hardware breakpoints now work
for me powerpc. These patches don't depend on that patch though.

This is because we don't check to see if the break point is associated
with task before we deference the task_struct pointer. This checks pointer
before dereferencing it.

These should never happen since we always turn on MSR TM when in userspace. We
don't do lazy TM.
Hence if we hit this, we barf and kill the task as something's gone horribly

Becky,
This has been broken in linux-next for a while. Looks like a merge
issue but you were the last to touch it...
