[PATCH v1 0/3] Putting some basic order on isa extension lists

I don't know for sure that I have not re-ordered something that is
sacrosanct. It seems that all of these are internal use structs, and
should be okay, barring the obvious exception of the, intentionally
re-ordered, isa_ext_arr.

With that caveat out of the way - all I did here was try to make things
consistent so that it'd be easier to point patch submitters at a "do
this order please".

I never know which of these can be moved without breaking stuff - but
they all seem to be internal use stuff since they're not in uapi?

For v2, I added another path with some uapi docs & switched to Drew's
suggested ordering of alphabetically, except in the /proc/cpuinfo array,
as per the discussion today in the pw-sync call. I also added a
sprinkling of comments around which things should be sorted in which
way.

I guess consider this an RFS, with the S being Screaming in the case of
me doing something you abhor :)

Thanks,
Conor.
