Subject: [PATCH 0/2] time: Fix races at clocksource switch time

In testing some recent timekeeping changes, I found some problem
when changing clocksources.

These two patches close races at clocksource switch time. One I sent out
earlier, and have reworked to integrate Thomas' comments.

These two patches, along with Thomas' recent cleanup patches ontop can
be found here:
