Subject: [x86_64] kvm: export symbols to allow building
Message-id: 4A254034.2000700@redhat.com
O-Subject: [RHEL5.4 PATCH] Bug 501777 - kvm doesn't build on newer RHEL-5.4 kernels, BZ #501777
Bugzilla: 504038
RH-Acked-by: Don Dutile <ddutile@redhat.com>
RH-Acked-by: Chris Wright <chrisw@redhat.com>

BZ #501777  https://bugzilla.redhat.com/show_bug.cgi?id=501777

The KVM kernel module requires the export of
get_user_pages_fast() and smp_send_reschedule()
from RHEL-5.4 kernels as implemented by the
patch below.

The patch has been verified against build version
kernel-2.6.18-151.el5 which may be found here:

https://brewweb.devel.redhat.com/taskinfo?taskID=1822468

The proposed KVM-side patch may be found attached
to the BZ case (link above).
