linux-next: powerpc build failure

Hi Paul,

Today's linux-next tree build (powerpc ppc64_defconfig) failed like this:

  UPD     include/linux/compile.h
arch/powerpc/mm/built-in.o: In function `ht64_insert_pte':
hash_native_64.c:(.text+0x4756): undefined reference to `_PAGE_HPTE_SUB0'

I have reverted commit 2d9a973b0fee245af43b73412a08e88bc955644d
("powerpc: Free a PTE bit on ppc64 with 64K pages") for now.

Yup, that's the way to go. It's broken, I'll have to do things a bit
differently, I "forgot" our 64K SPU hack when using 4K pages assumes
we have the same PTE format :-( I'll have to implement a separate low
level asm function for hashing 64K pages on a 4K kernel.

Ben.
