[patch 00/15] clocksource/events: Overhaul (un)registration

[Thomas Gleixner]

The clocksource_unregister() interface is broken. A clocksource can be
removed unconditionally even if there is no fallback clocksource
available. clocksources in a module can be removed as well. Aside of
that the registration part lacks a few sanity checks as well.

The clockevents layer does not allow unregistration, but for
reconfigurable hardware this is a must have feature.

The following patch series fixes the clocksource part and adds
unregister support for clockevent devices.

Thanks,
