From 29e86d94fd1745269523b42f81e4c6c1cae9b336 Mon Sep 17 00:00:00 2001 From: Collin Walling Date: Tue, 15 Sep 2020 15:44:09 -0400 Subject: [PATCH 1/9] s390/sclp: get machine once during read scp/cpu info 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.
