Hi Po-Hsu,

For artful/arm64, when I implemented the test, I hadn't realized CONFIG_VMAP_STACK had been backported to the 4.13/artful kernel (in 7b7dbeeef3b73294e525f368b03c3890459992a6). I have fixed the qrt test to reflect that in https://git.launchpad.net/qa-regression-testing/commit/?id=6cda576b8fc2f3c6f08d7f6a0bd7408918180ab8 .

For bionic 4.15/linux-kvm, the kernel config there is missing having CONFIG_VMAP_STACK set:

  $ grep VMAP_STACK debian.kvm/config/config.common.ubuntu
  CONFIG_HAVE_ARCH_VMAP_STACK=y
  # CONFIG_VMAP_STACK is not set

The security team would like to see that fixed.

Thanks!
