Bug Description

We need to make some minor changes to get lttng-modules-dkms to
build on the nexus4 (mako) on Raring.

a) Revert trace event modifications to realign these with standard
upstream and Ubuntu trace events.

b) Remove a modpost Makefile CONFIG_NO_ERROR_ON_MISMATCH which
is too exacting and we should relax this to align with standard Ubuntu modpost settings.

I installed the image + headers + lttng + lttng-modules-dkms. Then manually installed the kernel into the flash boot region, rebooted and was able to get lttng to work:

root@ubuntu-phablet:~# lttng list -k
Kernel events:
-------------
      timer_init (loglevel: TRACE_EMERG (0)) (type: tracepoint)
      timer_start (loglevel: TRACE_EMERG (0)) (type: tracepoint)
      timer_expire_entry (loglevel: TRACE_EMERG (0)) (type: tracepoint)
      timer_expire_exit (loglevel: TRACE_EMERG (0)) (type: tracepoint)
      timer_cancel (loglevel: TRACE_EMERG (0)) (type: tracepoint)
      hrtimer_init (loglevel: TRACE_EMERG (0)) (type: tracepoint)
      hrtimer_start (loglevel: TRACE_EMERG (0)) (type: tracepoint)
etc..

So, verified OK.
