[PATCH v3 0/5] virtio-scsi multiqueue
This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends). The patches build on top of the new virtio APIs
at http://permalink.gmane.org/gmane.linux.kernel.virtualization/18431;
the new API simplifies the locking of the virtio-scsi driver nicely,
thus it makes sense to require them as a prerequisite.

[PATCH v4 0/6] Support calling functions on dedicated physical cpu
Some hardware (e.g. Dell Studio laptops) require special functions to
be called on physical cpu 0 in order to avoid occasional hangs. When
running as dom0 under Xen this could be achieved only via special boot
parameters (vcpu pinning) limiting the hypervisor in it's scheduling
decisions.
This patch series is adding a generic function to be able to temporarily

This series implements virtio-scsi queue steering, which gives
performance improvements of up to 50% (measured both with QEMU and
tcm_vhost backends).
This version rebased on Rusty's virtio ring rework patches, which
has already gone into virtio-next today.
We hope this can go into virtio-next together with the virtio ring
rework pathes.
