Subject: [PATCH 2/5] powerpc/book3e-64: Move the default cpu table entry
Date: Wed, 19 Aug 2009 00:08:30 -0500	[thread overview]
Message-ID: <1250658513-13009-2-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <1250658513-13009-1-git-send-email-galak@kernel.crashing.org>

Move the default cpu entry table for CONFIG_PPC_BOOK3E_64 to the
very end since we will probably want to support both 32-bit and
64-bit kernels for some processors that are higher up in the list.
