Subject[PATCH 0/3] kunit: add support in kunit.py for --qemu_args
From
Note: this series applies on top of
https://lore.kernel.org/linux-kselftest/20220516194730.1546328-2-dlatypov@google.com/.
That patch greatly simplified the process of adding new flags.

This flag would let users pass additional arguments to QEMU when using a
non-UML arch to run their tests.
E.g. for kcsan's tests, they require SMP and with this patch, you can do
$ ./tools/testing/kunit/kunit.py run --kconfig_add=CONFIG_SMP --qemu_args='-smp 8'

This is proposed as an alternative to users manually creating new
qemu_config python files and also to [1], where we discussed checking in
a new x86_64 variant w/ `-smp 8` hard-coded into it.

This patch also contains a fix to the example `run_kunit` bash function
since it didn't quote properly and would parse the example above as
--qemu_args='-smp' '8'
no matter how you tried to quote your arguments.
