It would be great if the decoding information were available in some
form that is readily reused.  We'd like to have it for use in gdb as
well.  I don't really care what format; we can have gdb read anything.

It seems to me that it would be best if the kernel provided this data
somehow; since after all it's really just a description of the kernel
API.
