arm_gicv3_kvm: Fix compile warningpull-target-arm-20170904-1
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.
