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.
