kaf24@firebug.cl.cam.ac.uk 11d666ab5e Fix the issue of on x86_64, rhel4 can not get into runlevel 5.
Xserver will scan pci and the cirrus VGA driver will register
mmio each time, cause mmio array out of space.

kaf24@firebug.cl.cam.ac.uk 9ad74f9849 I cleaned up acm_ops.c and eliminated returns inside the switch
statement. When we need locks, we can place them now around the switch 
statement.

I also included the comments from Rusty and now return -EPERM for denied 
permission errors.

emellor@leeni.uk.xensource.com c039c43deb Added a count of the number of users of this block device, and refuse to close
down the frontend until that number becomes 0.  There are no reasonable
semantics for hot-unplugging a block device beneath a mounted filesystem, and
this solution ensures that the guest is not crashed nor the filesystem corruptedby the actions of the administrator.

kaf24@firebug.cl.cam.ac.uk 2fd270048e Remove CONFIG_PREEMPT configuration option from Xen kernel builds.
The option reduces overall system performance and makes little sense
when running over a preemptive hypervisor. Removing the option also
fixes some hypothetical races.

The forthcoming voluntary-preemption option will make much more sense
to enable when running over Xen.

PMD (Xen will not allow it). This is okay even across

contain no PTEs that become garbage across suspend/resume.

emellor@leeni.uk.xensource.com 92b5e81264 Don't treat the failure of ifconfig vifX.Y down as a fatal error. This hasn't
emerged as a problem in the field, AFAIK, but it seems that distro scripts
could have brought the device down already by this point (Debian stable's
net.agent does ifdown vifX.Y, and it wouldn't surprise me if someone decided
to do ifconfig vifX.Y down if this failed, for example).

Logging but ignoring the failure seems sensible.
