    [PATCH] Add printk_clock() · 31f6d9d6
    Andrew Morton authored
    ia64's sched_clock() accesses per-cpu data which isn't set up at boot time.
    Hence ia64 cannot use printk timestamping, because printk() will crash in
    sched_clock().
    
    So make printk() use printk_clock(), defaulting to sched_clock(), overrideable
    by the architecture via attribute(weak).
