Yes, include/asm is symlinked to include/asm-mips. Let me provide a
little more detail. I did not want to modify head.S (since this is a
kernel file) but I noticed an undefined macro,
kernel_entry_setup # cpu specific setup
and the include #include <kernel-entry-init.h>
I found at least one kernel-entry-init.h file in a hardware specific
directory so I made my own under include/asm-mips/rb500 and added a line
to the Makefile. Within kernel-entry-init.h are the include for
cacheops.h as well as the macro definition. regdef.h is included in
head.s.

Well, it looks like I am missing something somewhere, just need to pin
down what I did wrong.
