For a little while now (about a week IIRC) fs/dax.c has been breaking the ARM allmodconfig build due to a missing declaration of copy_user_page():

I have to confess I'm not 100% sure this isn't an ARM bug as it looks like include/mm.h ought to pull it in from asm/page.h but I'm not 100% sure where it *should* be coming from.
We don't provide copy_user_page() currently. There's a patch floating about to add it which Arnd has build-tested, which I've yet to queue. However, the new facility remains untested on ARM as I've no idea where to get the fs/dax.c patches from (I had asked willy, but he didn't respond to the request.) I'm not screen-scraping patch set off lkml.org.
