queues, contention on queuing operation could be greatly reduced.

TX queue to work on.  Only the related driver's TX queue serializer will

is used (*).

(*) Whether we should utilize multiple TX queues if ALTQ's packet scheduler

virtio-blk provides a paravirtualized storage controller, with one
disk per virtio device.

This driver is based on Tim Bisson's port of FreeBSD's virtio and
virtio-blk devices. Differences from Tim's port:

* Import all FreeBSD updates from 4/16 on.
* Remove indirect descriptor support from virtio device.
* Mark devices as D_MPSAFE; removes mplock around disk routines, they
  are all correctly self-synchronized.
* Implement devstat support.
* Move I/O completion routine to threaded taskqueue.
* Do not hold target spinlock around virtqueue notify.
* Move objcache caches to kmalloc.

libc - Add poor man's cache coloring optimization to nmalloc module.

* A series of large allocations in excess of 32KB will be offset by 4K from
  each other.  This fixes performance issues on SandyBridge and later cpus
  related to large matrix operations.

  This eats an extra 4K of VM for such allocations but does not eat any
  additional real memory.

* Greatly improves large FP matrix benchmarks.  Real-world effects are more

* The Sandybridge and later cpus use a virtually indexed, physically tagged
  L1 cache, and tend to be sensitive to substantially different memory
  addresses winding up on the same cache line.  Matrix operations (primarily
  benchmarks) can cause these sorts of effects.
