From bbfd3017eb0ae59fe799e67046914dd1f94a9767 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Mon, 16 Oct 2017 16:42:57 +0200 Subject: [PATCH] kvm: fix alignment of ram address Fix the wrong calculation of the delta, used to align the ram address. This only strikes if alignment has to be done.
