Here I made a few edits, but nothing major. Throughout the patch I
replaced "collected" with "harvested" since the documentation was using
it already and it's a bit more unique ("collect" reminds me too much of
garbage collection and perhaps could be confused with the kernel's
operation for the reset ioctl).

And this can be "#if KVM_DIRTY_LOG_PAGE_OFFSET > 0" instead.
