No real harm, but some architectures don't require alignment of thread_info,
and they might waste a few kb because of the forced alignment.
The easier solution should be to force the alignment in
arch/{sparc,m68k}/vmlinux.lds.S, like the other architectures have it.
m68k-sun3 currently aligns thread_info to PAGE_SIZE, m68k aligns it
to 8192. AFAICT, you can simply replace both with THREAD_SIZE.
