It does not apply to my tree.
Against which tree is this patchset ? Who is supposed to take it ?

Ok, we have the choice: 1. split the patchset into arch/arm changes and drivers/clocksource 2. I ack the patchset and Olof/Kevin take it 3. Olof/Kevin ack the patchset and I take it in my tree.
This is really becoming fuzzy.
If you want a maintainer to take a patchset you have to send an email --to him and --cc mailing list and others concerned by the patchset.
