Subject: [RFC, Patch 0/1] OProfile for Cell: Initial profiling support -- new patch

Hello,
I will be posting a patch that updates the OProfile kernel driver to
enable it for the Cell Broadband Engine processor. The patch is based
on Arnd Bergmann's arnd6 patchset for 2.6.18
(http://kernel.org/pub/linux/kernel/people/arnd/patches/2.6.18-arnd6/),
with Kevin Corry's cbe_pmu_interrupt patch on applied on top. Kevin
Corry's patch was submitted to the mailing lists earlier today and can
be found at:
http://marc.theaimsgroup.com/?l=linux-kernel&m=116360639928471&w=2).

I will also post an OProfile userpsace patch to the oprofile-list that
adds the necessary support for the Cell processor.

Thanks in advance for your review of this patch.

Based on review comments received so far, we will be posting an updated
kernel patch for OProfile for Cell. Most notably, this patch removes
some racey conditions between our "virtual counter" function and the
interrupt handler, as well as fixing the way we were restarting and
stopping our timer for the virtual counter.

Thanks.
