Subject: [PATCH 0/2] kselftest/arm64: Add coverage for the interaction of
 vfork() and GCS

I had cause to look at the vfork() support for GCS and realised that we
don't have any direct test coverage, this series does so by adding
vfork() to nolibc and then using that in basic-gcs to provide some
simple vfork() coverage.
