mm: alloc_contig_range: allow to specify GFP mask
Currently alloc_contig_range assumes that the compaction should be done
with the default GFP_KERNEL flags. This is probably right for all
current uses of this interface, but may change as CMA is used in more
use-cases (including being the default DMA memory allocator on some
platforms).
Change the function prototype, to allow for passing through the GFP mask
set by upper layers.
Also respect global restrictions by applying memalloc_noio_flags to the
passed in flags.
