Ok i'll keep this in mind :)

addr2line points me to irq_restore so that's definitely interesting.

vaibhav@vaibhav-VirtualBox:~/src/linux$ arm-linux-gnueabi-addr2line -f
-e vmlinux c0097518
arch_local_irq_restore
/home/vaibhav/src/linux/arch/arm/include/asm/irqflags.h:152

My kernel is based off v3.12 and the topmost commit in xen sources is:

    xen/evtchn: Fix build on ARM

    The recent event channel changes introduced by commit a77eb86 and before...
    break the compilation on Xen ARM. This commit adds missing includes in
    common/event_fifo.c and include/xen/sched.h.

    Signed-off-by: Julien Grall <julien.grall@xxxxxxxxxx>
    Acked-by: Ian Campbell <ian.campbell@xxxxxxxxxx>

I got the xen tools updated. Will update the xen image also and check
if it makes
a difference.

Vaibhav
