Subject: [PATCH 0/2] nohz: Deal with clock reprogram skipping issues

Now that we've understood the issue that Pavel and Tim have reported,
here's the new version of 24b91e360ef521a2808771633d76ebc68bd5604b that
Linus reverted. I took extra care on CPU hotplug as well. Hopefully this
time the fix doesn't introduce a new bug. The second patch should warn
when such an issue arise.

Thanks.
