Commit-ID: 9385d949d5bd0eb642ed05ea263c3638c9f4e372 Gitweb: http://git.kernel.org/tip/9385d949d5bd0eb642ed05ea263c3638c9f4e372 Author: Thomas Gleixner AuthorDate: Tue, 17 Sep 2013 18:53:08 + Committer: Thomas Gleixner CommitDate: Wed, 13 Nov 2013 20:21:47 +0100 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.
