From 1529ae1bc61a15e9a243dcbad70c95dfcdd1f0c5 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 20 Jan 2012 14:41:12 +0100 Subject: [PATCH] KVM: Update headers (except HIOR mess) This patch is basically what ./scripts/update-linux-headers.sh against upstream KVM's next branch outputs except that all the HIOR bits are removed. These we have to update with the code that uses them.
