From 028f042613c3c99db20dd7f4e4069fbbcea92dd7 Mon Sep 17 00:00:00 2001 From: Robin Getz Date: Mon, 10 Jul 2006 06:25:40 +0000 Subject: [PATCH] kallsyms: support kernel symbols in Blackfin on-chip memory The Blackfin arch has a discontiguous .text layout due to having on-chip instruction memory and no virtual memory support. As such, we need to add explicit checks for these additional .text regions.
