I have tested this patchset on both Intel and AMD systems. For the test on AMD systems, I made two rounds of tests. The first round only applied bug-fix patches 1-6. The second round applied the entire series. In both rounds, I used the test process at http://lists.xenproject.org/archives/html/xen-devel/2015-11/msg02590.html except that patch 13 there was replace by the patch in the attachment. In both rounds, I got the expect results. Tested-by: Haozhong Zhang Haozhong
