You may as well map the data space, too, since you have
reserved the entries.  Take advantage of that performance.
Also, some processor variants have very few TLB entries,
and may only reserve two entries (although the flag says
reserve 4).  Ensure there are sufficient resources to do
what you want.  This is the reason the option is configurable.

Scott had some concerns about pinning the data space too. That is
is why I left the data TLB pinning behind the the config option.

How to make better use of the remaining ITLB slots is tricky.
Somehow one would want to map at lest one to modules but I cannot see how.
