mm: cma_alloc: allow to specify GFP mask
Most users of this interface just want to use it with the default GFP_KERNEL flags, but for cases where DMA memory is allocated it may be called from a different context. No functional change yet, just passing through the flag to the underlying alloc_contig_range function.
