Guo Ren eb2ac8c497 csky: Set regs->usp to kernel sp, when the exception is from kernel ... [ Upstream commit f8e17c17b8 ] In the past, we didn't care about kernel sp when saving pt_reg. But in some cases, we still need pt_reg->usp to represent the kernel stack before enter exception. For cmpxhg in atomic.S, we need save and restore usp for above.
