This patch adds the option "superpages" to the domain configuration file. If it is set, the domain is populated using 2M pages. This code does not support fallback to small pages. If the domain can not be created with 2M pages, the create will fail. The patch also includes support for saving and restoring domains with the superpage flag set. However, if a domain has freed small pages within its physical page array and then extended the array, the restore will fill in those freed pages. It will then attempt to allocate more than its memory limit and will fail. This is significant because apparently Linux does this during boot, thus a freshly booted Linux image can not be saved and restored successfully. Signed-off-by: Dave McCracken <dcm@mccr.org>
