From ee73887e92a69ae0a5cda21c68ea75a27804c944 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 29 Apr 2014 12:58:03 -0700 Subject: sparc64: Fix range check in kern_addr_valid(). In commit b2d438348024b75a1ee8b66b85d77f569a5dfed8 ("sparc64: Make PAGE_OFFSET variable."), the MAX_PHYS_ADDRESS_BITS value was increased (to 47). This constant reference to '41UL' was missed.
