[Xen-devel] [PATCH 4/6] mm: New XENMEM space, XENMAPSPACE_gmfn_range

[Jean Guyader <jean.guyader@xxxxxxxxxxxxx>]

XENMAPSPACE_gmfn_range is like XENMAPSPACE_gmfn but it runs on
a range of pages. The size of the range is defined in a new field.

This new field .size is located in the 16 bits padding between .domid
and .space in struct xen_add_to_physmap to stay compatible with older
versions.
