teach copy_page_to_iter() to handle compound pages
In situation when copy_page_to_iter() got a compound page the current
code would only work on systems with no CONFIG_HIGHMEM. It *is* the majority
of real-world setups, or we would've drown in bug reports by now. Still needs
fixing.
Current variant works for solitary page; rename that to
__copy_page_to_iter() and turn the handling of compound pages into a loop over
subpages.
