[for-4.17 v2 0/3] GitLab CI cleanup and boot time cpupools test

[for-4.17 v2 0/3] GitLab CI cleanup and boot time cpupools test

[Michal Orzel]

This patch series performs a small cleanup before the release and adds
a test for validating boot time cpupools feature introduced in 4.17.

Notes for the release manager:
Benefits:
 - improved dom0less test coverage
 - tested feature that is introduced in 4.17
Risks:
 - CI pipeline failure

[for-4.17 v2 1/3] automation: qemu-alpine-arm64-gcc: Use kernel 5.19

[Michal Orzel]

After qemu-smoke-arm64 was changed to use kernel 5.19 we end up having
two kernel configurations. This is something not needed and maintaining
a single kernel version is always easier. Modify qemu-alpine-arm64-gcc
to use kernel 5.19 and remove kernel 5.9 from tests-artifacts.

[for-4.17 v2 2/3] automation: qemu-smoke-arm64: Silence ifconfig error messages

[Michal Orzel]

During the ping test, dom1 tries to assign an ip to eth0 in a loop.
Before setting up the network interface by dom0, this results in
printing the following error message several times:
(XEN) DOM1: ifconfig: SIOCSIFADDR: No such device

Silence this by redirecting stderr/stdout to /dev/null as we do not
care about the output and we should not pollute the log file.

[for-4.17 v2 3/3] automation: Add a new job for testing boot time cpupools on arm64

[Michal Orzel]

Add a new test job qemu-smoke-arm64-gcc-boot-cpupools that will execute
script qemu-smoke-arm64.sh to test boot time cpupools feature.
Enable CONFIG_BOOT_TIME_CPUPOOLS for the arm64 build and add a new test
case in qemu-smoke-arm64.sh that if selected will make use of the
ImageBuilder feature to create cpupool with cpu@1, null scheduler and
assign it to domU. Add a check in dom0 xen.start to see if domU is
assigned a Pool-1 with null scheduler.

Take the opportunity to refactor the qemu-smoke-arm64.sh script as
follows:
 - use domU_check to store the test's commands to be run from domU
 - use dom0_check to store the test's commands to be run from dom0
 - use fdtput instead of sed to perform dtb modifications
 - use more meaningful messages for "passed" variable. This way we can
   grep for messages reported either by domU or dom0 and get rid of
   assumption that tests can only be run from domU

Changes in v2:
- use ImageBuilder feature to create boot-time cpupools
