Hi all,

With just Linus' tree, today's linux-next build (powerpc ppc64_defconfig)
produced this warning:

fs/dax.c: In function 'dax_iomap_fault':
fs/dax.c:1462:35: warning: passing argument 2 of 'dax_iomap_pmd_fault' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
return dax_iomap_pmd_fault(vmf, ops);
^
fs/dax.c:1439:12: note: expected 'struct iomap_ops *' but argument is of type 'const struct iomap_ops *'
static int dax_iomap_pmd_fault(struct vm_fault *vmf, struct iomap_ops *ops)
^

Introduced by commit

a2d581675d48 ("mm,fs,dax: change ->pmd_fault to ->huge_fault")

which missed fixing up the !CONFIG_FS_DAX_PMD case.
