4.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Marc Zyngier <marc.zyngier@arm.com> 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.
