From cdbdbe65f5f006cba208accee5a126c659d4b867 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Fri, 13 Nov 2009 08:52:21 -0600 Subject: [PATCH] ppc/85xx: Fix how we determine the number of CAM entries We were incorrectly use the max CAM size as the number of entries in the array for setting up the addrmap. We should be using the NENTRY field which is the low 12-bits of TLB1CFG.
