Hi Thomas,

before respinning the complete series, I thought we could take a look at
the changes to the timer core, since I expect them to need to be refined
for an actual submission.

The first patch is the patch you proposed to serialize callers of
clockevents_update_freq(). I guess you may find some better words to
describe your changes. I found it not that easy to find a nice
description for somebody else's patch.

The second patch is my shot at extending clockevents_update_freq()
to also handle timers in periodic mode. In my approach I assume that
simply calling the timer's 'set_mode()' API takes care of programming an
appropriate interval based on the current timer frequency. If that
doesn't work for all timers, I guess it would require a new API call. Or
I just missed some other way.

	Thanks,
	Sören
