currently the property entry kunit tests are built if CONFIG_KUNIT=y.
This will cause warnings when merged with the kunit tree that now
supports tristate CONFIG_KUNIT. While the tests appear to compile
as a module, we get a warning about missing module license.
It's better to have a per-test suite CONFIG variable so that
we can do selective building of kunit-based suites, and can
also avoid merge issues like this.

This patch series is a follow up to "lib/vdso, x86/vdso: Fix fallout
from generic VDSO conversion" [1].
The main purpose is to complete the 32bit vDSOs conversion to use the
legacy 32bit syscalls as a fallback. With the conversion of all the
architectures present in -next complete, this patch series removes as
well the conditional choice in between 32 and 64 bit for 32bit vDSOs.
This series has been rebased on linux-next/master.

2.24.1
kunit tests that do not support module build should depend
on KUNIT=y rather than just KUNIT in Kconfig, otherwise
they will trigger compilation errors for "make allmodconfig"
builds.

Please read the attached investment proposal and reply for more details.
Are you interested in loan?
