[Xen-devel] [PATCH v5 3/4] libxl: Store e820 map in xc_dom_image

[Maran Wilson <maran.wilson@xxxxxxxxxx>]

From: Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>

We will later copy it to hvm_start_info.

(Also remove stale comment claming that xc_dom_image.start_info_seg is
only used for HVMlite guests)

Changes in v5
* No need to allocate/copy to dom->e820, we can just point to the
  already allocated e820.
