sparc/oprofile: Convert timer_stop() to use synchronize_rcu()2018-11-09T05:43:20+00:00Paul E. McKenneypaulmck@linux.ibm.com2018-10-30T22:45:04+00:00urn:sha1:8fa9eb388eb00f7a63caf0fd370f8c134015fc1f
Now that synchronize_rcu() waits for preempt-disable regions of code
in addition to explicitly marked RCU read-side critical sections,
synchronize_rcu() can be used in place of synchronize_sched(). This
commit therefore makes that change.

Use a per-cpu 'wd_enabled' boolean and a global atomic_t count
of watchdog NMI enabled cpus which is set to '-1' if something
is wrong with the watchdog and it can't be used.

It all lives in the oprofile support code currently and we will need
to share this stuff with NMI watchdog and perf_counter support.

We use clock cycle counter, adjusted to HZ.
This can be extended to sun4v based processors as well, as they
also have a proper overflow interrupt facility for the performance
counters.
