From 05c484355fa6b22af5c1c96db154f108f8b5c625 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Sun, 18 Nov 2007 00:41:56 +0800 Subject: [PATCH] Blackfin arch: remove dump_thread() The only user is the a.out support. It was therefore removed prior to the blackfin merge from all architectures not supporting a.out. Currently, Blackfin doesn't suppport a.out.
