People have been changing things in linux-next and the powerpc patches
are hurting.

I'll disable this patch series for now.  Can you please redo
powerpc-32-drop-get_pteptr.patch and
powerpc-add-support-for-folded-p4d-page-tables.patch (and
powerpc-add-support-for-folded-p4d-page-tables-fix.patch)?

Thanks.
