[RFC PATCH 1/2] Add a new register offset let interrupt reason available
From: Li Liu <john.liuli at huawei.com>
Add a new register offset VIRTIO_MMIO_ISRMEM which help to
estblish a shared memory region between virtio-mmio driver
and qemu with two purposes:
1.Guest virtio-mmio driver can get the interrupt reason.
2.Check irqfd enabled or not to register different irq handler.

[RFC PATCH] virtio-mmio: support for multiple irqs
As the current virtio-mmio only support single irq,
so some advanced features such as vhost-net with irqfd
are not supported. And the net performance is not
the best without vhost-net and irqfd supporting.
This patch support virtio-mmio to request multiple
irqs like virtio-pci. With this patch and qemu assigning
multiple irqs for virtio-mmio device, it's ok to use
vhost-net with irqfd on
