Date: Tue, 1 Jan 2008 17:35:47 +0200 From: Avi Kivity <avi@...ranet.com> To: linux-kernel@...r.kernel.org, kvm-devel@...ts.sourceforge.net Subject: [PATCH 21/54] KVM: Export include/linux/kvm.h only if $ARCH actually supports KVM Currently, make headers_check barfs due to <asm/kvm.h>, which <linux/kvm.h> includes, not existing. Rather than add a zillion <asm/kvm.h>s, export kvm.h only if the arch actually supports it.
