Indeed! Nice to see you, even if virtually.

Whatever you want to work on is OK with me.

Keep in mind that these structures may vary by machines.

They are opaque types to userspace, but internally we
have variations like on x86 we have lock elision bits,
and on hppa we some compat words.

Feel free to support those architectures you care about,
but it would be nice if you provided enough flexibility
to allow other authors to copy and modify.

As always, please make sure you have FSF copyright
assignments in place for all authors.

Cheers,
Carlos.
