Use gnttab_unmap_refs_async() to wait until the mapped pages are no
longer in use before unmapping them.
This allows blkback to use network storage which may retain refs to
pages in queued skbs after the block I/O has completed.

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

Test this too. We fetch this from the Canonical Kernel Team (ckt)
repo, but do not encode `ckt' in the branch name, in case this becomes
a proper stable tree.
(I have set up this branch on the osstest with the mg-branch-setup
script in this version of this tree.)

The scratch frame mappings for ballooned pages and the m2p override

The scratch pages did not ensure that the page was not in use. In

When unmapping grants, instead of converting the kernel map ops to
unmap ops on the fly, pre-populate the set of unmap ops.
This allows the grant unmap for the kernel mappings to be trivially
batched in the future.

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

Use the foreign page flag in netback to get the domid and grant ref

Introduce gnttab_unmap_refs_async() that can be used to safely unmap
pages that may be in use (ref count 1). If the pages are in use the
unmap is deferred and retried later. This polling is not very clever
but it should be good enough if the
