Ingo, Please pull the printk support in dynticks mode patches that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git tags/printk-dynticks-for-mingo-v2 for you to fetch changes up to 74876a98a87a115254b3a66a14b27320b7f0acaa: printk: Wake up klogd using irq_work (2012-11-18 01:01:49 +0100) It is based on v3.7-rc4. Changes since previous pull request include support for irq work flush on CPU offlining and acks from Steve. The rest hasn't changed except some comment fix. Thanks. ---------------------------------------------------------------- Support for printk in dynticks mode: * Fix two races in irq work claiming * Generalize irq_work support to all archs * Don't stop tick with irq works pending. This fix is generally useful and concerns archs that can't raise self IPIs. * Flush irq works before CPU offlining. * Introduce "lazy" irq works that can wait for the next tick to be executed, unless it's stopped. * Implement klogd wake up using irq work. This removes the ad-hoc printk_tick()/printk_needs_cpu() hooks and make it working even in dynticks mode.
