Ok, but I'm getting the following error after applying the first patch
from your series:

error: patch failed: arch/powerpc/include/asm/pgalloc-64.h:166
error: arch/powerpc/include/asm/pgalloc-64.h: patch does not apply
error: arch/powerpc/mm/hash64_64k.c: No such file or directory

Or am I missing something?
