Subject: vmi: fix nohz compile
From: Zachary Amsden <[EMAIL PROTECTED]>
More goo from hrtimers integration. We do compile and run properly with NO_HZ
enabled. There was a period when we didn't because of a missing export, but
that was since fixed.
And with the clocksource code now firmly in place, we can get rid of code that
fixes up the wallclock, since this is done in the common infrastructure. This
actually fixes a timer bug as well, that was caused by do_settimeofday no
longer being callable with interrupts disabled due to the use of
on_each_cpu().
