David Hildenbrand 35af90b702 mm/page_alloc: sort out the alloc_contig_range() gfp flags mess 
It's all a bit complicated for alloc_contig_range().  For example, we
don't support many flags, so let's start bailing out on unsupported ones
-- ignoring the placement hints, as we are already given the range to
allocate.

While we currently set cc.gfp_mask, in __alloc_contig_migrate_range() we
simply create yet another GFP mask whereby we ignore the reclaim flags
specify by the caller.  That looks very inconsistent.

Let's clean it up, constructing the gfp flags used for
compaction/migration exactly once.  Update the documentation of the
gfp_mask parameter for alloc_contig_range() and alloc_contig_pages().
