From 77ac58ddc6be324abc3451ae78a1799efa7cc3b7 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 17 Sep 2014 12:21:29 +0200 Subject: dma: do not depend on kvm_enabled() Memory barriers are needed also by Xen and, when the ioeventfd bugs are fixed, by TCG as well. sysemu/kvm.h is not anymore needed in sysemu/dma.h, move it to the actual users.
