FWIW I'm waiting for the patch in: http://marc.info/?l=linux-kernel&m=123391426917099&w=2 to settle and make it's way into the tree as that bug has been crashing my machines for a while. It's definitely something needed for -stable as well. 1) Don't try to use the NMI watchdog on cpus where we know it won't work. These chips lack the performance counter overflow interrupt which is essential to this scheme. 2) We have a million exception fixup stubs generated which are all essentially the same, so have one stub for each case and point the exception table entries to them. 3) Fix probe_kernel_{read,write}() on sparc64, based upon reports and patches from Chris Torek. Please pull, thanks a lot.
