kernel - Remove most global atomic ops for VM page statistics
* Use a pcpu globaldata->gd_vmstats to update page statistics.
* Hardclock rolls the individual stats into the global vmstats structure.
* Force-roll any pcpu stat that goes below -10, to ensure that the low-memory
handling algorithms still work properly.
