#     powerpc/preempt: Don't touch the idle task's preempt_count during hotplug
#     
#     Powerpc currently resets a CPU's idle task preempt_count to 0 before
#     said task starts executing the secondary startup routine (and becomes an
#     idle task proper).
#     
#     This conflicts with commit f1a0a376ca0c ("sched/core: Initialize the
#     idle task with preemption disabled").
#     
#     which initializes all of the idle tasks' preempt_count to
#     PREEMPT_DISABLED during smp_init(). Note that this was superfluous
#     before said commit, as back then the hotplug machinery would invoke
#     init_idle() via idle_thread_get(), which would have already reset the
#     CPU's idle task's preempt_count to PREEMPT_ENABLED.
#     
#     Get rid of this preempt_count write.
#     
#     Fixes: f1a0a376ca0c ("sched/core: Initialize the idle task with preemption disabled")
