Subject: 32-bit kernel on PPC64 supported?
Date: Fri, 18 Jul 2008 20:43:08 +0200 [thread overview]
Message-ID: <200807182043.08991.marvin24@gmx.de> (raw)
Hi,
while trying to cleanup some configs/makefiles for ppc64 I noticed, that
CONFIG_POWER4 implies CONFIG_PPC64 and vice versa in all defconfigs.
So I want to boldly replace CONFIG_POWER4 by CONFIG_PPC64 - ugh.
However, there are some constructs like:
#ifndef CONFIG_PPC64
...
#ifdef CONFIG_POWER4
...
#endif
...
#endif /* CONFIG_PPC64 */
in which POWER4 is always undefined, e.g. in
include/asm-powerpc/mmu_context.h. Maybe this is a leftover from times, where
64-bit kernels where not supported on Powermacs. Is this 32-bit support still
necessary?
Greetings
Marvin
