sparc: Use preempt_schedule_irq The low level preemption code fiddles with the PREEMPT_ACTIVE bit for no reason and calls schedule() with interrupts disabled, which is wrong to begin with. Remove the PREEMPT_ACTIVE fiddling and call the proper schedule_preempt_irq() function. Signed-off-by: Thomas Gleixner <t...@linutronix.de> Acked-by: David S.
