File x86-cpu-Use-max-host-physical-address-if.patch of Package qemu.28166
From: Yang Weijiang <weijiang.yang@intel.com> Date: Wed, 13 Jan 2021 17:04:30 +0800 Subject: x86/cpu: Use max host physical address if -cpu max option is applied Git-commit: 5a140b255df922b98a165f0a2919602943c9062f References: bsc#1188299 QEMU option -cpu max(max_features) means "Enables all features supported by the accelerator in the current host", this looks true for all the features except guest max physical address width, so add this patch to enable it.
