Re: [Xen-devel] [PATCH-4.5 v3 10/12] xen/arm: don't protect GICH and lr_queue accesses with gic.lock

GICH is banked, protect accesses by disabling interrupts.
Protect lr_queue accesses with the vgic.lock only.

When the interrupt is an SPI, the lr_queue is shared between every VCPU. Using only vgic.lock seems wrong to me.
