[PATCH 11/13] xen/gntdev: update to new mmu_notifier semantic

From: jglisse
Date: Thu Aug 31 2017 - 17:18:39 EST


From: JÃrÃme Glisse <jglisse@xxxxxxxxxx>

Call to mmu_notifier_invalidate_page() are replaced by call to
mmu_notifier_invalidate_range() and thus call are bracketed by
call to mmu_notifier_invalidate_range_start()/end()

Remove now useless invalidate_page callback.
