Merge git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-2.6-mn10300
* git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-2.6-mn10300:
Separate out the proc- and unit-specific header directories from the general
Move arch headers from include/asm-mn10300/ to arch/mn10300/include/asm/.
