commit 629a5d87e26fe96bcaab44cbb81f5866af6f7008 upstream.
Sync include/xen/interface/io/ring.h with Xen's newest version in
order to get the RING_COPY_RESPONSE() and RING_RESPONSE_PROD_OVERFLOW()
macros.
Note that this will correct the wrong license info by adding the
missing original copyright notice.
