Module Name:    src
Committed By:   yamt
Date:           Tue Jul  5 14:03:07 UTC 2011

Modified Files:
        src/sys/uvm: uvm_km.c uvm_map.c

Log Message:
- fix a use-after-free bug in uvm_km_free.
  (after uvm_km_pgremove frees pages, the following pmap_remove touches them.)
- acquire the object lock for operations on pmap_kernel as it can actually be
  raced with P->V operations.  eg. pagedaemon.
