Add await in destroy_qp() so that all references to qp are dereferenced
and qp is freed in destroy_qp() itself.  This ensures freeing of all QPs
before invocation of dealloc_ucontext(), which prevents loss of in use
qpids stored in the ucontext.

Drivers cannot check the udata for validity when doing destroy as there
will be no way to report this error back to the uverbs.

Since udata is new for destroy no driver should start to use it - instead
drivers should opt for the ioctl interface and define it in a way where it
cannot fail due to incorrect data.

Remove the checks on udata construction so EFA is consistent with
everything else.

     saves storage space on larger server systems where perf.data size
     can easily reach several tens or even hundreds of GiBs, especially
     when profiling with DWARF-based stacks and tracing of context
     switches.

  perf record:

   - Improve -user-regs/intr-regs suggestions to overcome errors

  perf annotate:

   - Remove hist__account_cycles() from callback, speeding up branch
     processing (perf record -b)

  perf stat:

   - Add a 'percore' event qualifier, e.g.: -e
     cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for
     both hardware threads in a core.

     We can already do this with --per-core, but it's often useful to do
     this together with other metrics that are collected per hardware
     thread.

     I.e. now its possible to do this per-event, and have it mixed with
     other events not aggregated by core.

   - Map Brahma-B53 CPUID to cortex-a53 events.
