iomap_write_end cannot return an error, so switch it to return
size_t instead of int and remove the error checking from the callers.
Also convert the arguments to size_t from unsigned int, in case anyone

Size the uptodate array dynamically to support larger pages in the

but with a 2MB maximum page size, we'd have to allocate more than 4kB

Pass the full length to iomap_zero() and dax_iomap_zero(), and have
them return how many bytes they actually handled. This is preparatory
work for handling THP, although it looks like DAX could actually take

interface on a host the same

Commit 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")

I asked the folks who have this particular hardware to try it out as I
don't have access to this one. Hopefully we get the results back soon
and once we do, I'll let you know.
