From 0ccee4e6277b4324785e91b488b19f7f30303e32 Mon Sep 17 00:00:00 2001 From: York Sun Date: Tue, 2 Dec 2014 11:21:09 -0800 Subject: powerpc/mpc85xx: Fix DDR TLB mapping leftover Commit f29f804a93e87c17670607641d120f431a3b0633 generalized the TLB mapping function, but made the DDR mapping leftover size to zero, causing the message not printed.
