Subject: [PATCH] m68knommu: fix invalid flags on coldfire pit clocksource
The m68knommu coldfire pit clocksource looks like it was incorrectly
marked as a continuous clocksource. Running with it marked as a
continuous clocksource could cause hangs when the system switches to
highres mode or enables nohz.
This patch removes the CLOCK_SOURCE_IS_CONTINUOUS flag on the coldfire pit
clocksource. This will disallow systems using this clocksource from
entering oneshot mode (disabling highres timers and nohz).
