[RFC: 2.6 patch] dump_thread() cleanup

From: Adrian Bunk
Date: Wed Nov 23 2005 - 17:36:20 EST

This patch contains the following cleanups:
- create one common dump_thread() prototype in kernel.h
- dump_thread() is only used in fs/binfmt_aout.c and can therefore be
removed on all architectures where CONFIG_BINFMT_AOUT is not
available
