Hello all,

This are the latest version of the patches.

Lots of things have changed since the last submission. A few of
which I remember:
- VNC copy / paste works* (* conditions apply)
  - client vnc copies get propagated to guest port 3 (/dev/vmch3)
  - guest writes to port 3 (/dev/vmch3) go straight to client's clipboard
- sysfs hooks to autodiscover ports
- support for 64 ports in this version (MAX_VIRTIO_SERIAL_PORTS). More
  ports can be added by introducing a new feature flag to maintain
  backward compat. However, till this code gets accepted upstream, the
  value of that #define can change. I think 64 ports are enough for
  everyone.
- remove support for control queue (though this queue could make a
  comeback for just one use-case that I can currently think of:
  to prevent rogue (host) userspace putting lots of data into a guest
  that goes unconsumed for a while, increasing the memory pressure. To
  prevent this a threshold level can be decided upon and a control
  message can be sent to host userspace to prevent any more writes
  to the port.
- numerous fixes

There still exist a few kmalloc/kfree-related debug logs that spew up
in the guest but I haven't been able to track them down.

As for the merge with virtio-console, Christian has voiced some oppostion
to that idea. For the merge to happen, the kernel folks have to agree
in merging the driver as well and I can proceed once we have a resolution
on this.

Other than that, a few more rebases have to be done to the qemu code to
make it apply to qemu-upstream.

Please give this a good review. 

Thanks,
	Amit.
