From cae6292b653f5e3308bf2787a54b7dcd2cc7e2b3 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 15 Feb 2011 12:42:57 +0100 Subject: ARM: 6672/1: LPAE: use phys_addr_t instead of unsigned long in mapping functions The unsigned long datatype is not sufficient for mapping physical addresses >= 4GB. This patch ensures that the phys_addr_t datatype is used to represent physical addresses when converting from a PFN.
