Please find the v2 of cma related powerpc fadump fixes. Patch-1 is a change in mm/cma.c to make sure we return an error if someone uses cma_init_reserved_mem() before the pageblock_order is initalized. I guess, it's best if Patch-1 goes via mm tree and since rest of the changes are powerpc fadump fixes hence those should go via powerpc tree. Right? v1 -> v2: ========= 1. Review comments from David to call fadump_cma_init() after the pageblock_order is initialized. Also to catch usages if someone tries to call cma_init_reserved_mem() before pageblock_order is initialized.
