[Qemu-devel] [PATCH] virtio-blk: change config to guest endian

[Qemu-devel] [PATCH] virtio-blk: change config to guest endian

[Liu Yu]

Since virtio-blk in kernel has already changed, qemu needs to be updated.
see http://thread.gmane.org/gmane.linux.kernel.virtualization/5776/focus=580

Only tested it on branch kvm-70rc1 for e500/powerpc platform.
