Pull up following revision(s) (requested by tsutsui in ticket #504):
sys/arch/x68k/dev/event_var.h: revision 1.9
Make sure to take proc_lock mutex on calling psignal(9) in EV_WAKEUP() macro
as sys/dev/sun/event_var.h does.
Fixes immediate KASSERT(mutex_owned(proc_lock)) panic during running Xserver
on DIAGNOSTIC kernel.
Should be pulled up to netbsd-6.
