[PATCH] x86_64: Set compatibility flag for 4GB zone on IA64
IA64 traditionally had a 4GB DMA32 zone. Set the compatibility flag to keep old drivers working. For new drivers it would be better to use ZONE_DMA32 now. Cc: tony.luck@intel.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
