Today's -next fails to build an ARM allmodconfig due to:

due to 16d4d43595b47 (xfs: split direct I/O and DAX path) which added an
unconditional reference to dax_do_io(). DAX is explicitly disabled on
32 bit ARM due to problems with virtual aliasing caches (it's not clear
to me that it shouldn't also be disabled for arm64 for the same reason).

expect there to be a problem for arm64.
