[Xen-devel] [PATCH] [HVM] fix HVM log dirty issue

["Zhai, Edwin" <edwin.zhai@xxxxxxxxx>]

These patches fix some issues for HVM log dirty in qemu:
* Add necessary logging dirty in qemu to avoid guest error with
intensive disk access when live migration
* Take place of shared memory between qemu and migration tools by new
added hypercall, which is clean and simple
