Modified files:
sys/vm device_pager.c phys_pager.c swap_pager.c
Log:
Protect pager object creation with sx locks.
Protect pager object list manipulation with a mutex.
It doesn't look possible to combine them under a single sx lock because
creation may block and we can't have the object list manipulation block
on anything other than a mutex because of interrupt requests.
