"virtio: core support for config generation"
fixed reading up 64 bit values, adding generation
checks for such reads.
By mistake, it left an explicit get call in place
as well. the result is that the value is read twice,
the first result is disca

This simply reorders functions in virtio_config
so width access wrapper helpers are all together.
Drops an extra empty line while we are at it.

Virtio 1.0 doesn't include a modern balloon device.
But it's not a big change to support a transitional
balloon device: this has the advantage of supporting
existing drivers, transparently.

We added transitional device support to balloon driver,
so we don't need to black-list it in core anymore.

I sent a patch about page allocation for less fragmentation.
http://permalink.gmane.org/gmane.linux.kernel.mm/130599
It proposes a page allocator allocates pages in the same pageblock
for the drivers to move their unmovable pages. Some drivers which comsumes many
pages
and increases system fragme
