Subject: [patch 0/2] sched: Cleanup idle task double initialization

Idle tasks are initialized via __sched_fork() twice, which can be trivially
avoided as pointed out here:

    https://lore.kernel.org/all/8734p4ymqj.ffs@tglx

As this got ignored, the tasteless hack in init_scx_entity() to work around
it stayed and found it's way into mainline.

Mop it up after the fact to not further proliferate technical debt.

Thanks,

	tglx
