Increases the device timeout from 10s to 5 minutes, giving the user a
visual indication during that time in case there are problems. The patch
is a backport of changesets 144 and 150 in the Xenbits tree.Cc: Jeremy Fitzhardinge

When printing a warning about a timed-out device, print the
current state of both ends of the device connection (i.e., backend as
well as frontend). This backports half of changeset 146 from the
Xenbits tree.Cc: Jeremy Fitzhardinge

The logic of is_disconnected_device/exists_disconnected_device is wrong
in that they are used to test whether a device is trying to connect (i.e.
connecting). For this reason the patch fixes them to not consider a
Closing or Closed device to be connecting. At the same time the patch
also renames the functions according to what they really do; you could
say a closed device is "disconnected" (the old name), but not "connecting"
(the new name).This patch is a backport of changeset 909 from the Xenbits tree.

The xenfs filesystem exports various interfaces to usermode. Initially
this exports a file to allow usermode to interact with xenbus/xenstore.Traditionally this appeared in /proc/xen. Rather than extending procfs,
this patch adds a backward-compat mountpoint on /proc/xen, and provides
a xenfs filesystem which can be mounted there.Signed-off-by: Alex Zeffertt

There are four operating modes Xen code may find itself running in:

- pv domUClean up predicates for testing for these states to make them more consistent.

Avoid allocations causing swap activity on the resume path by
preventing the allocations from doing IO and allowing them
to access the emergency pools.These paths are used when a frontend device is trying to connect
to its backend driver over Xenbus. These reconnections are triggered
on demand by IO, so by definition there is already IO underway,
and further IO would naturally deadlock. On resume, this path
is triggered when the running system tries to continue using its
devices. If it cannot then the resume will fail; to try to avoid this
we let it dip into the emergency pools.[ linux-2.6.18-xen changesets e8b49cfbdac, fdb998e79aba ]

When restoring, rebind the existing xenbus irq to the new xenbus event
channel. (It turns out in practice that this is always the same, and
is never updated on restore. That's a bug, but Xeno-linux has been
like this for a long time, so it can't really be fixed.)Signed-off-by: Jeremy Fitzhardinge

Add module aliases to support autoprobing modules
for xen frontend devices.Signed-off-by: Mark McLoughlin
Signed-off-by: Ingo Molnar
Signed-off-by: Thomas Gleixner -
When the xen block frontend driver is built as a module the module load
is only synchronous up to the point where the frontend and the backend
become connected rather than when the disk is added.This means that there can be a race on boot between loading the module and
loading the dm-* modules and doing the scan for LVM physical volumes (all
in the initrd). In the failure case the disk is not present until after the
scan for physical volumes is complete.Taken from:

Don't use alloc_vm_area()/free_vm_area() directly, instead define
xen_alloc_vm_area()/xen_free_vm_area() and use them.alloc_vm_area()/free_vm_area() are used to allocate/free area which
are for grant table mapping. Xen/x86 grant table is based on virtual
address so that alloc_vm_area()/free_vm_area() are suitable.
On the other hand Xen/ia64 (and Xen/powerpc) grant table is based on
pseudo physical address (guest physical address) so that allocation
should be done differently.
The original version of xenified Linux/IA64 have its own
allocate_vm_area()/free_vm_area() definitions which don't allocate vm area
contradictory to those names.
Now vanilla Linux already has its definitions so that it's impossible
to have IA64 definitions of allocate_vm_area()/free_vm_area().
Instead introduce xen_allocate_vm_area()/xen_free_vm_area() and use them.Signed-off-by: Isaku Yamahata

This communicates with the machine control software via a registry
residing in a controlling virtual machine. This allows dynamic
creation, destruction and modification of virtual device
configurations (network devices, block devices and CPUS, to name some
examples).[ Greg, would you mind giving this a review? Thanks -J ]
