Xen should return ~0 when there is no suitable ioreq server to dispatch
the request.
Without this patch, QEMU stubdom will fail to start because hvmloader
fails following assertion:

In an x86 PV guest, get_user_pages_fast() on a userspace address range
containing foreign mappings does not work correctly because the M2P
lookup of the MFN from a userspace PTE may return the wrong page.
Force get_user_pages_fast() to fail on such addresses by marking the PTEs
as special.

Unmapping may require sleeping and we unmap while holding priv->lock, so
convert it to a mutex.

For a PV guest, use the find_special_page op to find the right page.
To handle VMAs being split, remember the start of the original VMA so
the correct index in the pages array can be calculated.

The legacy save/restore infrastructure requires several function pointers from
the toolstack (libxl or Xend in the past) in order to work, and for HVM guests

The scratch frame mappings for ballooned pages and the m2p override
are broken. Remove them in preparation for replacing them with
simpler mechanisms that works.
The scratch pages did not ensure that the page was not in use. In
particular, the foreign page could still be in use by hardware. If
From: Jennifer Herbert
Ballooned pages are always used for grant maps which means the
original frame does not need to be saved in page->index nor restored
after the grant unmap.
This allows the workaround in netback for the conflicting use of the
(unionized) page->index and page->pfmemalloc to b
From: Jennifer Herbert
Use the foreign page flag in netback to get the domid and grant ref
needed for the grant copy. This signficiantly simplifies the netback
code and makes netback work with foreign pages from other backends
(e.g., blkback).
This allows blkback to use iSCSI disks provided by
This series fixes a number of long-standing bugs in the handling of
grant maps. Refer to the following for all the details.

In summary, the important uses that this enables are:
1. Block backends can use networked storage safely.
The optional find_special_page VMA operation is used to lookup the
pages backing a VMA. This is useful in cases where the normal
mechanisms for finding the page don't work. This is only called if
the PTE is special.
One use case is a Xen PV guest mapping foreign pages into userspace.
