Merge remote-tracking branch 'sstabellini/xen-20130625' into staging
# By Paul Durrant (2) and Stefano Stabellini (1) # Via Stefano Stabellini * sstabellini/xen-20130625: Move hardcoded initialization of xen-platform device. Allow use of pc machine type (accel=xen) for Xen HVM domains. Revert "xen: start PCI hole at 0xe0000000 (same as pc_init1 and qemu-xen-traditional)" Message-id: alpine.DEB.2.02.1306251323220.4782@kaball.uk.xensource.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
