From 57702891376d4636b5eab4a89145152a0342c987 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Mon, 7 Nov 2022 17:13:48 +0100 Subject: [PATCH] Revert "s390x/s390-virtio-ccw: add zpcii-disable machine property" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit 59d1ce44396e3ad2330dc3261ff3da7ad3a16184. The "zpcii-disable" machine property is redundant with the "interpret" zPCI device property. Remove it for clarification.
