Rebased against kernel-3.10.0-1160.el7. data-read-mostly.patch.disabled remains disabled as we hit several build errors like: "Found a jump label at __netif_receive_skb_core()+0x50, using key netstamp_needed. Jump labels aren't supported with this kernel. Use static_key_enabled() instead." Signed-off-by: Joe Lawrence <joe.lawrence@redhat.com>
