VM statistics: Make timer deferrable
...
VM statistics updates do not matter if the kernel is in idle powersaving
mode. So allow the timer to be deferred.
It would be better though if we could switch the timer between deferrable
and nondeferrable based on differentials present. The timer would start
out nondeferrable and if we find that there were no updates in the last
statistics interval then we would switch the timer to deferrable. If the
timer later finds again that there are differentials then go to
nondeferrable again.
And yet another way would be to run the timer shortly before going to idle?
The solution here means that the VM counters may be slightly off during
idle since differentials may be still pending while the timer is deferred.
