Subject: [kvm-unit-tests PATCH v3 8/9] s390x: snippets: Set stackptr and stacktop in cstart.S
Date: Thu, 7 Oct 2021 08:50:26 +0000 [thread overview]
Message-ID: <20211007085027.13050-9-frankja@linux.ibm.com> (raw)
In-Reply-To: <20211007085027.13050-1-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.
