That was the plan for 1.10+. And I thought that was because 1.10
is what people actually started implementing for real, but based on
the comment from Palmer that is not actually true. Sigh..
I guess at least for Linux we'd then want to make sure 1.9.1 support
is in mainline as well, probably based off a config option.
And if someone has a a good contact to the RISC-V website admins
it would be very helpful to restore a link to the specification as well
so that things other than the direct link work.
