2.6.34-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alan Cox <alan(a)linux.intel.com>

commit 79907d89c397b8bc2e05b347ec94e928ea919d33 upstream.

10, 233 is allocated officially to /dev/kmview which is shipping in
Ubuntu and Debian distributions. vhost_net seem to have borrowed it
without making a proper request and this causes regressions in the other
distributions.

vhost_net can use a dynamic minor so use that instead. Also update the
file with a comment to try and avoid future misunderstandings.
