Subject: Re: [PATCH 11/14] powerpc: Use macros for .data.page_aligned
 section.

Hi Tim,

Firstly, patches for a particular architecture should really be cc'd to
the list associated with that architecture.  In this case,
linuxppc-dev@...abs.org (cc'd).

This moves the page_aligned section from a common part of the
vmlinux.lds to a 32 bit only part.  Was that intentional?
