linux-stable.git/arch/nios2/kernel/entry.S, branch v3.19 Linux kernel stable tree nios2: Use preempt_schedule_irq 2014-12-31T03:04:58+00:00 Tobias Klauser tklauser@distanz.ch 2014-12-31T02:53:11+00:00 1b0f44923e186b2f9383b3260f6b5fbfc77b9e4a Follow aa0d53260596 ("ia64: Use preempt_schedule_irq") and use preempt_schedule_irq instead of enabling/disabling interrupts and messing around with PREEMPT_ACTIVE in the nios2 low-level preemption code ourselves. Also get rid of the now needless re-check for TIF_NEED_RESCHED, preempt_schedule_irq will already take care of rescheduling. This also fixes the following build error when building with CONFIG_PREEMPT: arch/nios2/kernel/built-in.o: In function `need_resched': arch/nios2/kernel/entry.S:374: undefined reference to `PREEMPT_ACTIVE' Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Acked-by: Ley Foon Tan <lftan@altera.com>

preempt_schedule_irq instead of enabling/disabling interrupts and

code ourselves. Also get rid of the now needless re-check for
TIF_NEED_RESCHED, preempt_schedule_irq will already take care of

This also fixes the following build error when building with
