Is there a userspace counterpart to it?

As this KVM/x86 related changes have not been merged to mainline
kernel, some little modification is needed on mainline Qemu.

Could you please point me to these changes?

As I tested this patch on a 128GB RAM Linux VM with no huge pages, the
time of enabling dirty log will decrease obviously.

I'm not sure how realistic that is. Not having huge pages tends to lead
to pretty bad performance in general...

Thanks,
