Since Guo has sent out the series, so I dropped my version and just provide those in my local repo but missing in Guo's series. However, this doesn't mean this series depends on Guo's series, in fact except the first one, the remaining three patches are independent on generic entry. NOTE: patch4 can also clean up arch/riscv/kernel/mcount-dyn.S as well but there's a trivial difference in the context saving, I dunno whether is it better to clean up mcount-dyn.S too, any suggestions are welcome.
