Log Message:
Pull up following revision(s) (requested by bouyer in ticket #5965):
sys/uvm/uvm_glue.c: revision 1.90
remove the assertion in uvm_swapout_threads() about LSONPROC lwps
not running on the same CPU as the swapper. l_stat is protected by
sched_lock, which isn't held here, so we can race with that lwp
starting to run and see its l_cpu not updated yet, as in PR 31870.
we check l_stat again in uvm_swapout() while holding sched_lock,
so the race itself is harmless.
