From 2f099a280e92c259598d8ed8da82c7ec2dd49845 Mon Sep 17 00:00:00 2001 From: Jonas Bonn Date: Fri, 2 Mar 2012 07:56:09 +0100 Subject: [PATCH] openrisc: fix virt_addr_valid virt_addr_valid() shouldn't be comparing the address to memory_end which is a phys_addr_t. Change this to do like other arches and check that the address falls within a valid page frame.
