[PATCH 00/45] arm Spectre fix backport review for LTS 4.9

[Alex Shi]

Hi All,

Resent without non-upstream patches.

This backport patchset fixed the spectre 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.

No bug found from kernelci.org and lkft testing. It also could be gotten from:

git://git.linaro.org/kernel/linux-linaro-stable.git v4.9-spectre-upstream-only

Comments are appreciated!

Regards
Alex
