From 79c3095fb39964d0d44368cbbb4eff5b52c43d2c Mon Sep 17 00:00:00 2001 From: Sonny Rao Date: Thu, 19 Aug 2010 18:08:09 +0000 Subject: powerpc: Export memstart_addr and kernstart_addr on ppc64 Some modules (like eHCA) want to map all of kernel memory, for this to work with a relocated kernel, we need to export kernstart_addr so modules can use PHYSICAL_START and memstart_addr so they could use MEMORY_START. Note that the 32bit code already exports these symbols.
