pv_ops Xen domU support has been there since Linux 2.6.24, and like you
said, it is included in the upstream/mainline Linux kernel, so it's always
there to use without extra patches.
Also with pv_ops the same kernel image can be used on baremetal (without
Xen), and also as Xen domU.

Yes it's separate patching, and custom forward-porting, so pv_ops is much
easier solution.
