    sys/vm               phys_pager.c 
  Fix the phys_pager in the way similar to the rev. 1.83 of the
  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.
