From bd9262d95f9172a5f4897aeea341c219a6c6cf96 Mon Sep 17 00:00:00 2001 From: Hu Tao Date: Tue, 10 Jun 2014 19:15:19 +0800 Subject: hostmem: separate allocation from UserCreatable complete method This allows the superclass to set various policies on the memory region that the subclass creates. Drops hostmem-ram's complete method accordingly. Signed-off-by: Paolo Bonzini Signed-off-by: Hu Tao Acked-by: Michael S. Tsirkin Signed-off-by: Michael S.
