We've left out the SPARC port for now. Our current guess is that there's
not enough demand for it to justify the maintenance and testing costs.
But, we could be wrong there, and if so we can easily bring it in again.
We're just being a bit cautious here, since it's always easier to add a
this later, compared to removing it later.
The SPARC port has also served as a good template for what a port would
look like on hardware with VA-masking support, but I'm hoping the
aarch64 port can fill that role going forward.

Let us know if there's something we can do to help.
