From 7a0eb1960e8ddcb68ea631caf16815485af0e228 Mon Sep 17 00:00:00 2001
From: Avi Kivity <avi@redhat.com>

Subject: KVM: Avoid using CONFIG_ in userspace visible headers

Kconfig symbols are not available in userspace, and are not stripped by
headers-install.  Avoid their use by adding #defines in <asm/kvm.h> to
suit each architecture.
