Commit 27ac792ca0b0a1e7e65f20342260650516c95864
(PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architectures)
causes on some architectures (e.g. avr32 and mips) compile errors
like the following in some configurations starting with:

<-- snip -->

...
CC init/main.o
In file included from
/home/bunk/linux/kernel-2.6/git/linux-2.6/include/linux/utsname.h:35,
from /home/bunk/linux/kernel-2.6/git/linux-2.6/init/main.c:20:
/home/bunk/linux/kernel-2.6/git/linux-2.6/include/linux/sched.h: In function 'arch_pick_mmap_layout':
/home/bunk/linux/kernel-2.6/git/linux-2.6/include/linux/sched.h:2149: error: implicit declaration of function 'PAGE_ALIGN'
make[2]: *** [init/main.o] Error 1

<-- snip -->

and more nasty problems follow later.

My suggestion is to:
- revert commit 27ac792ca0b0a1e7e65f20342260650516c95864 and then
- fix all PAGE_ALIGN() instances without moving them.

Unifying code is a good thing, but in this case it is not worth the
trouble it causes by poking into the heart of our headers mess.
