src/sys/arch/xen/xen [netbsd-5]: evtchn.c
Log Message:
Pull up following revision(s) (requested by bouyer in ticket #39):
sys/arch/xen/xen/evtchn.c: revision 1.40
evtchn_do_event(): in our C implementation of spllower(), if a handler fails
to restore the spl (shouldn't happen, but ...), we could end up with a
higther pending ipl set and never cleared because iplbit already
handled this level. while (iplmask != 0) {} would then never be true,
and we'd end up triggering KASSERT(iplbit != 0).
Now print the faultly handler and reset the IPL, and start the whole
pending IPL handling again if needed.
