Subject[PATCH 0/2] RT: Enhance PREEMPT_TRACE with deeper stacks
Date
This series changes the PREEMPT-TRACE behavior for reporting critical
sections. The previous code reported 2 frames per section. The new code uses
the save_stack_trace facility to save an arbitrary number of frames (currently
set to 5 via a #define)

For what its worth, these patches assisted me with debugging some issues in
-rt. The second patch is really a workaround for where X86_64 frame-pointers
apparently are not working under certain circumstances.
