Modified files:
sys/vm vm_map.c
Log:
- Avoid a lock-order reversal between Giant and a system map mutex that
occurs when kmem_malloc() fails to allocate a sufficient number of vm
pages. Specifically, we avoid the lock-order reversal by not grabbing
Giant around pmap_remove() if the map is the kmem_map.
