    Merge branch 'nohz/printk-v8' into irq/core · 07793144

    Conflicts:
    	kernel/irq_work.c
    
    Add support for printk in full dynticks CPU.
    
    * 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.
