Thomas Gleixner a5fd9733a3 tick/powerclamp: Remove tick_nohz_idle abuse ... commit 4dbd27711c "tick: export nohz tick idle symbols for module use" was merged via the thermal tree without an explicit ack from the relevant maintainers. The exports are abused by the intel powerclamp driver which implements a fake idle state from a sched FIFO task. This causes all kinds of wreckage in the NOHZ core code which rightfully assumes that tick_nohz_idle_enter/exit() are only called from the idle task itself. Recent changes in the NOHZ core lead to a failure of the powerclamp driver and now people try to hack completely broken and backwards workarounds into the NOHZ core code. This is completely unacceptable and just papers over the real problem. There are way more subtle issues lurking around the corner. The real solution is to fix the powerclamp driver by rewriting it with a sane concept, but that's beyond the scope of this. So the only solution for now is to remove the calls into the core NOHZ code from the powerclamp trainwreck along with the exports.
