From 9385d949d5bd0eb642ed05ea263c3638c9f4e372 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 17 Sep 2013 18:53:08 +0000 Subject: 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 Acked-by: David S.
