Maksim Yevmenkin 251386b4b2 Tweak condition for disabling allocation from per-CPU buckets in
low memory situation. I've observed a situation where per-CPU
allocations were disabled while there were enough free cached pages.
Basically, cnt.v_free_count was sitting stable at a value lower
than cnt.v_free_min and that caused massive performance drop.
