2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------ From: Alex Williamson <[email protected]> commit 7b668357810ecb5fdda4418689d50f5d95aea6a8 upstream. We typically batch unmaps to be lazily flushed out at regular intervals. When we destroy a domain, we need to force a flush of these lazy unmaps to be sure none reference the domain we're about to free.
