No, the 5/6 and 6/6 split is what we agreed, thanks. On 6/6 I'm still
missing the ntpd side, see my reply there.

AFAIK we agreed on patches 1-4: the tickless run you did for me
(rodolfo-14-tickless-1hz) had all four applied. If 1 and 2 alone are
enough, could you put numbers for that in the commit message too?

And for the UAPI, an RFC first please. :-)
