kernel - Remove ad-hoc increment/decrement of vm->vm_sysref
* Remove the ad-hoc increment/decrement of vm->vm_sysref when pulling data
out for a ps. Acquire p->p_token instead.
This is an attempt to determine whether these adhoc operations are
responsible for causing a race that results in the seg-fault issue we
see on monster.
