4.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marc Zyngier <[email protected]>

commit dd5f1b049dc139876801db3cdd0f20d21fd428cc upstream.

The INTID mask is wrong, and is made a signed value, which has
nteresting effects in the KVM emulation. Let's sanitize it.
