I planed to do similar generic entry transaction as Guo Ren did[1], and I had some commits in local. Since Guo has sent out the series, 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.

Since v1: - consolidate gp saving/restoring in mcount-dyn.S as well - avoid non-trival memory waste if NR_CPUs is large - collect Reviewed-by tag.
Hi Guo,
I only added your reviewed-by tag to patch1, but dropped tag for patch3 and patch4 because the patch changed a bit.
Thanks
