[Qemu-devel] [PULL 23/77] i386: remove the new CPUID 'PCONFIG' from Icelake-Server CPU model

[Paolo Bonzini]

From: Robert Hoo <address@hidden>

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.
