From 5a140b255df922b98a165f0a2919602943c9062f Mon Sep 17 00:00:00 2001 From: Yang Weijiang Date: Wed, 13 Jan 2021 17:04:30 +0800 Subject: x86/cpu: Use max host physical address if -cpu max option is applied 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.
