[PATCHv7 1/8] printk: use vprintk_func in vprintk()

Show all headers | View raw

vprintk(), just like printk(), better be using per-cpu printk_func
instead of direct vprintk_emit() call. Just in case if vprintk()
will ever be called from NMI, or from any other context that can
deadlock in printk().
