From 7f70baeeb9e2d2b2a37a4bd3727d709547c4ae41 Mon Sep 17 00:00:00 2001 From: Vladimir Murzin Date: Tue, 14 Apr 2015 15:48:30 -0700 Subject: memtest: use phys_addr_t for physical addresses Since memtest might be used by other architectures pass input parameters as phys_addr_t instead of long to prevent overflow.
