Subject: [PATCH v4 1/6] s390x: Don't do a normal reset on the initial cpu
Date: Wed, 27 Nov 2019 12:50:41 -0500 [thread overview]
Message-ID: <20191127175046.4911-2-frankja@linux.ibm.com> (raw)
In-Reply-To: <20191127175046.4911-1-frankja@linux.ibm.com>
The initiating cpu needs to be reset with an initial reset. While
doing a normal reset followed by a initial reset is not wrong per se,
the Ultravisor will only allow the correct reset to be performed.
