Linux kernel source tree

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().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
