I double-checked that futex_waitv() doesn't need any architecture specific
hacks, and that the list above is complete.

Should I take this through the asm-generic tree, or would you send it
through the
tip tree?

I think that adding it to asm-generic tree make sense to me.

The selftest doesn't build with old headers, I needed this:
