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. Any comments are appreciated!
