Acked-by: Jacob Shin <jacob.shin@amd.com>

hpa, we need this patch: https://lkml.org/lkml/2012/8/24/469 and the above
2 from Yinghai to handle corner case E820 layouts.

I got an email from Greg KH that 1bbbbe779aabe1f0768c2bf8f8c0a5583679b54a is
queued for stable, so these need to go to stable as well.

Thanks,

-Jacob
