[Xen-devel] [PATCH 3/6] xen mtrr: Use generic_validate_add_page()

[Jeremy Fitzhardinge <jeremy@xxxxxxxx>]

From: Mark McLoughlin <markmc@xxxxxxxxxx>

The hypervisor already performs the same validation, but
better to do it early before getting to the range combining
code.

[ Impact: cleanup, avoid Xen console noise ]
