Oh, I have no A73/A75 cpu, so I can not reproduce meltdown bug.

We believe the LTS is the base kernel for android/lsk, so the fixing
patches should get it first and then merge to other tree.

It is the first patchset for meltdown. Yes, I will resent this patchset
with versioning after the renesas board booting fixed.

The meltdown and spectre is 2 different bugs, the fixing patchset are
isolated each other. So I did the backport as 2 different patchset. And
merging them together is relative simple. I will comming with a merge
patch next time, after the meltdown patchset ready.(the kernelci didn't
works well in recent days)
