Modified Files:
src/sys/kern: kern_lwp.c
Log Message:
Sprinkle a bunch more calls to lwp_need_userret(). There should be no
functional change but it does get rid of a bunch of assumptions about how
mi_userret() works making it easier to adjust in that in the future, and
works as a kind of documentation too.
