Subject: [PATCH] hw/isa/vt82c686: Keep track of PIRQ/PINT pins separately
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cheery-pick from f33274265a242df5d9fdb00915fe72fbb1b2a3c4

Move calculation of mask after the switch which sets the function
number for PIRQ/PINT pins to make sure the state of these pins are
kept track of separately and IRQ is raised if any of them is active.
