Subject: [PATCH 2/6] powerpc: Move CONFIG_PPC64 into CPU selection

From: Arnd Bergmann <[email-masked]>
Date: Wed, 02 May 2007 13:47:11 +0200

Currently, PPC64 is a top level configuration option in
arch/powerpc/Kconfig, which is somewhat unconventional.

Moving it into the CPU selection menu is a natural choice,
and is transparent to the rest of the configuration logic.
