CVS commit: src/sys/arch/xen/xen

Module Name:    src
Committed By:   cherry
Date:           Sun Nov 25 20:56:33 UTC 2012

Modified Files:
        src/sys/arch/xen/xen: evtchn.c

Log Message:
Do not escalate the local spl while taking the interrupt handler list
lock. Re-entrance is protected against within the events handler
framework by toggling interrupts/events, so we don't need (and cannot
use) the spl framework in that path. The other consumers (interrupt
registration/removal code) are not spl sensitive wrt this lock.
