Ditto. Who is even hosting this google drive anyway? I'd rather see
GitHub links to docs from the releases, but since youre pointing at the
ISA manual I suppose those do not really exist.

Acked, I'll fix all these as "Links:"

Regarding the pdf sources themselves, I actually used the links as
referred on the RISC-V wiki [1] which is the wiki mentioned from the
riscv.org website [2]. I do not like it but there does not seems to have
a proper specification release website...

Maybe pointing only to a specific commit on the github repo that
mentioned that the extension was ratified is better.

Thanks,

Clément
