The patch to which I'm replying removes the above calls.  These calls are
necessary to shutdown various bits of CPU-clock dependent hardware
before changing the CPU clock, and restore them - reconfiguring them
for the new clock rate after the transition has happened.

So, if you're removing these calls, what replaces them?  I don't see
anything which does without the above set.

The other patch on which you commented about unnecessary read
locks being taken:

[PATCH 181/228] cpufreq: move freq change notifications to cpufreq

That calls these notifiers, for all platforms except the ones that have
set CPUFREQ_ASYNC_NOTIFICATION, before and after calling
->target_index()..

And so functionally the code is supposed to be the same.. Unless I
have done some stupid mistake..
