From 9f029603abb1472a33e008f9ea4127cc52566986 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 6 May 2013 16:48:02 +0200 Subject: [PATCH] memory: Introduce address_space_lookup_region This introduces a wrapper for phys_page_find (before we complicate address_space_translate with IOMMU translation). This function will also encapsulate locking and reference counting when we introduce BQL-free dispatching.
