:I have been wondering this for some time. There are many kernel
:submaps: exec_map, clean_map,
:etc. But if you look the code in vm_map_find(), we have to call splvm()
:for kmem_map and its
:submap mb_map, but not for other kernel submaps. So is there anything
:special with these two
:kernel submaps?
:
:Thanks for any help.

The kmem_map and mb_map's can be modified from interrupts.
The other maps cannot.
