Do not use printk in raw_spinlocks,
it will cause BUG: Invalid wait context.

Here are the patchess for the next linux version. Add features
(seccomp-filter, err-injection, top-down mmap-layout, irq_work,
show_ipi, context-tracking), and fixup (kprobe_on_ftrace, ...),
Optimize (fault print, ...).
I think we'll finish most of features for arch/csky this year
