Subject: [PATCH v5 1/8] s390/sclp: get machine once during read scp/cpu info
Date: Thu, 10 Sep 2020 05:36:48 -0400	[thread overview]
Message-ID: <20200910093655.255774-2-walling@linux.ibm.com> (raw)
In-Reply-To: <20200910093655.255774-1-walling@linux.ibm.com>

Functions within read scp/cpu info will need access to the machine
state. Let's make a call to retrieve the machine state once and
pass the appropriate data to the respective functions.
