Raw Blame History

From 4f20f7503073886c51e82fbbdfe78d6c79ea5df7 Mon Sep 17 00:00:00 2001
From: Miroslav Rezanina <mrezanin@redhat.com>
Date: Fri, 11 Jan 2019 09:54:45 +0100
Subject: Machine type related general changes
This patch is first part of original "Add RHEL machine types" patch we
split to allow easier review. It contains changes not related to any
architecture.
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>
Rebase changes (4.0.0):
- Remove e1000 device duplication changes to reflect upstream solution
- Rewrite machine compat properties to upstream solution
Merged patches (4.0.0):
- d4c0957 compat: Generic HW_COMPAT_RHEL7_6
- cbac773 virtio: Make disable-legacy/disable-modern compat properties optional
