O-Subject: [RHEL-AV-8.2.0 qemu-kvm PATCH v3] RHEL: hw/i386: disable nested PERF_GLOBAL_CTRL MSR support
Bugzilla: 1559846

BZ: 1559846
BRANCH: rhel-av-8.2.0
BREW: 25775160
UPSTREAM: RHEL only

Nested PERF_GLOBAL_CTRL support is not present in the 8.2 kernel.  Drop the
features via compat properties, they will be moved to 8.2 machine type compat
properties in the 8.3 timeframe.

	No change, for v2 I mistakenly wrote "origin/rhel-av-8.2.0" as the
	branch. :(
