Hi,

Today's mainline 4.12-rc1 fails to build for the attached configuration
file on Power7 box with below errors.

$ make
fs/built-in.o: In function `xfs_file_iomap_end':
fs/xfs/xfs_iomap.c:1152: undefined reference to `.put_dax'
fs/built-in.o: In function `xfs_file_iomap_begin':
fs/xfs/xfs_iomap.c:1071: undefined reference to `.dax_get_by_host'

Also reproducible on latest linux-next, and the last successful build
was at next-20170510.

This should be fixed by https://patchwork.kernel.org/patch/9725515/

With the given patch, kernel build and boot is fine on ppc.
