I'm sending this to tech-kern as well as port-sun3 because I'm hoping
that the memory mapping mechanism is MI code.
I'm trying to enable the cache on a sun 3x. I know the cache tags
physical address but am having trouble in mapping this into memory.
I'm looking to enable the cache from machdep.c (the same place that
it's done on the sun 3 arch)
How do I do this?
Do I need to protect things with splhigh in machdep? The sun3 port
doesn't seem to so I'm not sure.
Any help appreciated
