Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git stable/for-linus-3.16-rc7-tag

Fix BUG when trying to expand the grant table.  This seems to occur
often during boot with Ubuntu 14.04 PV guests.

Apologies for the lateness of this pull request, but I've been on
vacation for the past two weeks.

Thanks.

David
