The symbol isn't export simply because it wasn't considered useful to
export it.  The expected use of mips_hpt_frequency is to initialize it
in the platform code as system startup time to the counter frequency,
then not look at it again.

I wonder how you're using it in your module?

Any export I would add - as per general policy for the kernel - an
EXPORT_SYMBOL_GPL btw.
