Christoph Hellwig 25078dc1f7 powerpc: use mm zones more sensibly ... Powerpc has somewhat odd usage where ZONE_DMA is used for all memory on common 64-bit configfs, and ZONE_DMA32 is used for 31-bit schemes. Move to a scheme closer to what other architectures use (and I dare to say the intent of the system): - ZONE_DMA: optionally for memory < 31-bit (64-bit embedded only) - ZONE_NORMAL: everything addressable by the kernel - ZONE_HIGHMEM: memory > 32-bit for 32-bit kernels Also provide information on how ZONE_DMA is used by defining ARCH_ZONE_DMA_BITS. Contains various fixes from Benjamin Herrenschmidt. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>		2018-12-20 22:21:20 +11:00
