[PATCH -V2 2/5] powerpc: Free up _PAGE_COHERENCE for numa fault use later

2013-11-18 Thread Aneesh Kumar K.V
From: "Aneesh Kumar K.V" Set memory coherence always on hash64 config. If a platform cannot have memory coherence always set they can infer that from _PAGE_NO_CACHE and _PAGE_WRITETHRU like in lpar. So we dont' really need a separate bit for tracking _PAGE_COHERENCE. Signed-off-by: Aneesh Kumar
