[PATCH] virtio-rng: support multiple virtio-rng devices
Current hwrng core supports to register multiple hwrng devices,
and there is only one device really works in the same time.
QEMU alsu supports to have multiple virtio-rng backends.
This patch changes virtio-rng driver to support multiple
virtio-rng devices.

[PATCH] virtio_rng: dont use vmalloced addresses for virtio
If virtio_rng is build as a module, random_data is an address in vmalloc
space. As virtio expects guest real addresses, this can cause any kind of
funny behaviour, so lets allocate random_data dynamically with kmalloc.

[PATCH 1/1] virtio: rng: disallow multiple device registrations, fixes crashes
The code currently only supports one virtio-rng device at a time.
Invoking guests with multiple devices causes the guest to blow up.
Check if we've already registered and initialised the driver. Also
cleanup in case of registration errors or hot-unplug so that a new
device can be used.

[PATCH 0/5] virtio: rng: fixes
Hi Rusty,
These are a few fixes for the virtio-rng driver. These were tested
using the not-yet-upstream virtio-rng device patch to qemu:
http://thread.gmane.org/gmane.comp.emulators.qemu/152668
Please apply.
Amit Shah (5):
virtio ids: fix comment for virtio-rng
virtio: rng: allow tasks to be killed that are waiting for rng input
virtio: rng: don't wait on host when module is going

[PATCHv4] virtio: find_vqs/del_vqs virtio operations
This replaces find_vq/del_vq with find_vqs/del_vqs virtio operations,
and updates all drivers. This is needed for MSI support, because MSI
needs to know the total number of vectors upfront.

go ahead and rebase the rest on top of this?
