I'm still not completly happy - it's a somewhat hackish solution.  I'm
thinking about a special file which can be mmaped into the process address
space and contains processor specific optimized code.  This also has other
uses.  One that comes to my mind are trampolines.  Right now we have to
make a syscall to flush the cache.  But on the RM7000 some cacheflush
operations are available in userspace.  I'm sure we can come up with more
uses.
