Subject: [kvm-unit-tests GIT PULL 13/17] s390x: snippets: Set stackptr and stacktop in cstart.S
Date: Mon, 18 Oct 2021 14:26:31 +0200 [thread overview]
Message-ID: <20211018122635.53614-14-frankja@linux.ibm.com> (raw)
In-Reply-To: <20211018122635.53614-1-frankja@linux.ibm.com>
We have a stack, so why not define it and be a step closer to include
the lib into the snippets.
