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
