I completly agree on that. Userspace should used <sys/regdef.h>,
<sys/fpregdef.h> and <sys/asm.h> for that which are the three de-facto
standard headers used throughout the MIPS world.
As for prefetching I like your suggestion of <asm/pref.h>. The prefetching
stuff is a Linux extension of asm.h. Moving it to it's own header file
along with the necessary bits for <linux/prefetch.h> would make a nice
