This patch adds locking to mse(4) and marks it MPSAFE.  It also adds some 
other cleanups such as using bus_*() instead of bus_space_*() and 
consolidating duplicate copies of its detach routine.  The patch is against 
HEAD but probably applies to 9 and 10 as well.

http://people.freebsd.org/~jhb/patches/mse_locking.patch

Note that this driver is using a deprecated API that will be removed in 11.  
If no one tests updates to this driver then it is not feasible to continue 
maintaining it in the tree.  In that case, it will be removed from HEAD one 
month from today.
