O-Subject: [RHEL-7.0 qemu-kvm PATCH] seabios paravirt: allow more than 1TB in x86 guest
Bugzilla: 989677
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>

This patch should be applied to the qemu-kvm rpm package at the same
time of the other one for seabios, so qemu will forward the ram_size
bits over 40 to seabios without losing them.
