Minchan Kim 23ba990a3e FROMLIST: mm: cma: introduce gfp flag in cma_alloc instead of no_warn ...

The upcoming patch will introduce __GFP_NORETRY semantic
in alloc_contig_range which is a failfast mode of the API.
Instead of adding a additional parameter for gfp, replace
no_warn with gfp flag.

To keep old behaviors, it follows the rule below.

  no_warn 			gfp_flags

  false         		GFP_KERNEL
  true          		GFP_KERNEL|__GFP_NOWARN
  gfp & __GFP_NOWARN		GFP_KERNEL | (gfp & __GFP_NOWARN)
