Hm, so the largest array seems to be in arch/blackfin/mach-bf537/boards/stamp.c at max of 43 entries. The new board info is ether 60 or 72 bytes, so we get 2 or 3K table. Not above page, but still could be packed I think. If we decide that we want to keep single chunk I'll just change the allocation to kcalloc. Let me know. We should probably redo patch #1 to avoid allocating empty property sets anyway. Thanks. -- Dmitry
