It was to keep asm/reg_8xx.h self sufficient for the following patch.

Also because including asm/mmu-8xx.h creates circular inclusion issue 
(mmu-8xx.h needs page.h which includes page-32.h, page-32.h includes 
cache.h, cache.h include reg.h which includes reg_8xx). The circle 
starts with an inclusion of asm/cache.h by linux/cache.h, himself 
included by linux/printk.h, and I end up with 'implicit declaration' issues.

How can I fix that ?
