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

v2: - update patch 3 to store the hwrng_register_done bool per-device rather than global - add patch 2 that re-arranges struct elems for better packing. Hi, This series enables virtio-rng to service the early randomness requests made by the hwrng core (patch 3), with Herbert's idea of using the scan routine. Patch 4 reverts the previous restriction, which no longer applies, to not send

Hi, This series enables virtio-rng to service the early randomness requests made by the hwrng core (patch 2), with Herbert's idea of using the scan routine. Patch 3 reverts the previous restriction, which no longer applies, to not send read requests to the host before successful probe. Patch 1 is a minor cleanup. Please review and apply, Amit Shah (3): virtio: rng: remove unused struct

This patchset replace CONFIG_PM with CONFIG_PM_SLEEP for all virtio drivers and virtio pci driver. With patch 1/2, two compile warnings are eliminated for virtio pci driver, and patch 2/2 is a clean up for all virtio drivers as suggested by Amit Shah.
