Modified files:
sys/vm phys_pager.c
Log:
Fix the phys_pager in the way similar to the rev. 1.83 of the
sys/vm/device_pager.c:
Protect the creation of the phys pager with non-NULL handle with the
phys_pager_mtx. Lookup of phys pager in the pagers list by handle is now
synchronized with its removal from the list, and phys_pager_mtx is put
before vm object lock in lock order. Dispose the phys_pager_alloc_lock
and tsleep calls, together with acquiring Giant, since phys_pager_mtx
now covers the same block.
