sys/uvm : uvm_map.c
Log message:
Unwire with map lock held
uvm_unmap_remove() effectively requires its caller to lock the vm map.
Even though uvm_map_teardown() is only called after a map's last reference
is dropped and is thus safe from other threads accessing the map, grab the
map's lock in uvm_map_teardown() to satify upcoming lock assertions in
uvm_unmap_remove().

- amd64, arm64, powerpc64 base builds and regress by bluhm
- amd64 and sparc64 base builds and regress by me
