[PATCH 1/3] powerpc: Define empty_zero_page[] in C

At the time being, empty_zero_page[] is defined in each platform head.S. Define it in mm/mem.c instead, and put it in BSS section instead of the DATA section. Commit 5227cfa71f9e ("arm64: mm: place empty_zero_page in bss") explains why it is interesting to have it in BSS. Signed-off-by: Christoph
