So, would you be OK with the following patch ? There is a symmetry just like irq_vectors tracepoints:
# perf list | grep -E "exception|irq_vectors" exceptions:page_fault_kernel_entry [Tracepoint event] exceptions:page_fault_kernel_exit [Tracepoint event] exceptions:page_fault_user_entry [Tracepoint event] exceptions:page_fault_user_exit [Tracepoint event] irq_vectors:call_function_entry [Tracepoint event] irq_vectors:call_function_exit [Tracepoint event] ... Maybe 2 tracepoints (instead of 4) should have been enough; however, there were already 1 tracepoint per mode before. Alexis.
