CVS commit: src/sys/arch/x86/x86

Module Name:    src

Modified Files:
        src/sys/arch/x86/x86: pmap.c

Log Message:
- Give pmap uvm_objects an empty pagerops to avoid special casing in UVM.
  (This use of uvm_object causes a disproportionate amount of work.)

- Undo the pmap_destroy()/pmap_delref() split.  I misunderstood the flow of
  control, and there's no need for this.

- For pmap_remove_pv(), always look up the pv_entry in advance as those
  calls will need to be covered by lock again soon.
