From b6f35b4966e0ae59cec45e5292b100698d12dc5f Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 5 Jul 2006 14:39:43 +1000 Subject: [POWERPC] Make crash.c work on 32-bit and 64-bit To compile kexec on 32-bit we need a few more bits and pieces. Rather than add empty definitions, we can make crash.c work on 32-bit, with only a couple of kludges.
