[PATCH v2] perf, x86-mm: declare page-faults tracepoints like irq-vectors ones

[Alexis Berlemont]

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.
