Subject: [patch 0/3] vmstat: Various enhancements

This addresses a couple of issues that came up last week in
the discussion about issues related to the blocking of
the execution of vmstat updates.

1. It makes vmstat updates execution deferrable again so that
   no special tick is generated for vmstat execution. vmstat
   is quieted down when a processor enters idle mode. This
   means that no differentials exist anymore when a processor
   is in idle mode.

2. Create a separate workqueue so that the vmstat updater
   is not blocked by other work requeusts. This creates a
   new kernel thread <sigh> and avoids the issue of
   differentials not folded in a timely fashion.
