Yes, it's not pretty... Last used bit is 15, hence bit 16 could be
used to signal to Xen whether the interrupt should be unmasked after
binding. I have a half-drafted patch, will finish it now.
Andreas, could you please give a try to the attached two patches? One
is for Xen and the other one is for QEMU.

Seems to work after I fixed a bug ;-)

-gflags |= masked ? 0 : XEN_PT_GFLAGSSHIFT_UNMASKED;
+gflags |= masked ? 0 : (1 << XEN_PT_GFLAGSSHIFT_UNMASKED);

Please let Jan and/or others review the patches.

Regards Andreas
