From 76e5a4d58357b9d077afccf7f7c82e17f733b722 Mon Sep 17 00:00:00 2001 From: Robert Hoo Date: Wed, 19 Dec 2018 21:44:40 +0800 Subject: [PATCH] i386: remove the new CPUID 'PCONFIG' from Icelake-Server CPU model PCONFIG is not available to guests; it must be specifically enabled using the PCONFIG_ENABLE execution control. Disable it, because no one can ever use it.
