Subject: [PATCH 1/3] arm/xen: Improve a size determination in
 __set_phys_to_machine_multi()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 4 Jun 2017 20:50:55 +0200

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
