Ingo,
This set addresses your review concerning the Kconfig layout.
Please note two things here that derive from what we agreed
on due to technical limitations:
* Now the full dynticks Kconfig is not hidden anymore behind its
high level dependencies. (ie: passive dependencies are now active).
There is an exception though with CONFIG_VIRT_CPU_ACCOUNTING_GEN
(Full dynticks cputime accounting) that is part of a choice menu
like PREEMPT_*. It seems such kconfig layout prevent from doing a remote
select on its choices. So it stays a passive dependency for now, until
Kconfig/Kbuild supports that (Cc'ing Michel Marek) or somebody shows
me what I did wrong ;)
* Ideally we want to reuse CONFIG_NO_HZ as a Kconfig that consolidate
the common code between CONFIG_NO_HZ_IDLE and CONFIG_NO_HZ_EXTENDED.
But we also want CONFIG_NO_HZ from old config files to map to CONFIG_NO_HZ_IDLE.
Both at the same time is not possible or we have a Kconfig circular
dependency. So I introduced a new CONFIG_NO_HZ_COMMON for common nohz code
and CONFIG_NO_HZ stays for backward compatibility by enabling CONFIG_NO_HZ_IDLE
by default.
If you're ok, please pull from:

Thanks.

Frederic Weisbecker (4):
nohz: Unhide full dynticks feature from its dependencies
nohz: Rename CONFIG_NO_HZ to CONFIG_NO_HZ_COMMON
nohz: Pack nohz Kconfig option in a menu of choices
nohz: Print final full dynticks CPUs range on boot
