Subject: [43/74] clocksource: fix compilation if no GENERIC_TIME

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Aaro Koskinen <aaro.koskinen@....fi>

commit a362c638bdf052bf424bce7645d39b101090f6ba upstream

Commit a9238ce3bb0fda6e760780b702c6cbd3793087d3 broke compilation on
platforms that do not implement GENERIC_TIME (e.g. iop32x):

  kernel/time/clocksource.c: In function 'clocksource_register':
  kernel/time/clocksource.c:556: error: implicit declaration of function 'clocksource_max_deferment'

Provide the implementation of clocksource_max_deferment() also for
such platforms.
