Hi Andy,
One the patch you created in -mm is causing compile warning. Here is the fix. Please verify.
Thanks, Badari
arch/powerpc/mm/init_64.c: In function `vmemmap_populated': arch/powerpc/mm/init_64.c:211: warning: passing arg 1 of `vmemmap_section_start' makes pointer from integer without a cast
vmemmap_section_start() gets called with an argument which is unsigned long.
