arm_gicv3_kvm: Fix compile warningpull-target-arm-20170904
Fix the following warning: /home/pranith/qemu/hw/intc/arm_gicv3_kvm.c:296:17: warning: logical not is only applied to the left hand side of this bitwise operator [-Wlogical-not-parentheses] if (!c->gicr_ctlr & GICR_CTLR_ENABLE_LPIS) { ^ ~ /home/pranith/qemu/hw/intc/arm_gicv3_kvm.c:296:17: note: add parentheses after the '!' to evaluate the bitwise operator first if (!c->gicr_ctlr & GICR_CTLR_ENABLE_LPIS) { ^ /home/pranith/qemu/hw/intc/arm_gicv3_kvm.c:296:17: note: add parentheses around left hand side expression to silence this warning if (!c->gicr_ctlr & GICR_CTLR_ENABLE_LPIS) { ^ This logic error meant we were not setting the PTZ bit when we should -- luckily as the comment suggests this wouldn't have had any effects beyond making GIC initialization take a little longer.
