	syssrc/sys/kern: kern_exit.c
	syssrc/sys/uvm: uvm_map.c

Log Message:
Don't uvm_deallocate() the address space in exit1().  The address
space is already torn down in uvmspace_free() when the vmspace
refrence count reaches 0.  Move the shmexit() call into uvmspace_free().

Note that there is a beneficial side-effect of deferring the unmap
to uvmspace_free() -- on systems where TLB invalidations are
particularly expensive, the unmapping of the address space won't
have to cause TLB invalidations; uvmspace_free() is going to be
run in a context other than the exiting process's, so the "pmap is
active" test will evaluate to FALSE in the pmap module.
