It is added. Note that I pass de list (cc->migratepages) to 
isolate_or_dissolve_huge_page().
It is done this way because we have to pass the list to 
isolate_huge_page() directly.
That is why I jump to isolate_success_no_list instead of isolate_sucess.

I know it is subtle, but I could not come up with a better name at that 
time.
