This series is to modularize RPMH driver The tracepoint in RPMH driver was changed to _rcuidle variant based on the test results of unmerged series [1] where .power_off callback from genpd reported RCU warnings. The series which finally got merged [2] uses CPU PM notifications and genpd .power_off callback is not implemented in RPMH driver to invoke rpmh_flush(). The CPU PM notifications are done with RCU non idle in kernel (see cpu_pm_notify() uses rcu_irq_enter_irqson() before notifications) However using _rcuidle variant prevented RPMH driver to compile as module since these _rcuidle are not exported symbols for tracepoints. This seris reverts the change [3] to remove _rcuidle variant for tracepoint as its no more valid test case (genpd .power_off is not implemented) and bring backs the change [4] that was reverted due to _rcuidle preventing to become modular.
