Subject: [PATCH 3.16.y-ckt 198/216] kvm: x86: drop severity of "generation wraparound" message

3.16.7-ckt4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paolo Bonzini <pbonzini@...hat.com>

commit a629df7eadffb03e6ce4a8616e62ea29fdf69b6b upstream.

Since most virtual machines raise this message once, it is a bit annoying.
Make it KERN_DEBUG severity.
