Hi All,

This backport patchset fixed the meltdown issue, it's original branch:
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/log/?h=kpti
A few dependency or fixingpatches are also picked up, if they are necessary
 and no functional changes.

The patchset also on repository:
	git://git.linaro.org/kernel/linux-linaro-stable.git lts-4.9-spectrevv2 

No bug found yet from kernelci.org and lkft testing.

No bugs is good, but does it actually fix the meltdown problem?  What
did you test it on?

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

And why are you making this patchset up?  What is wrong with the patches
in the android-common tree for this?

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.

Any comments are appreciated!

You need to start versioning this changeset, as I have no idea if this
is the "latest" one or not, right?>
Or have you not sent out this patchset before?  How does this interact
with the "spectre" patches?  Or am I totally confused here?

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)

Thanks
Alex
