Patch series "two small vmalloc cleanups". This patch (of 2): __vmalloc_area_node currently has four different gfp_t variables to just express this simple logic: - use the passed in mask, plus __GFP_NOWARN and __GFP_HIGHMEM (if suitable) for the underlying page allocation - use just the reclaim flags from the passed in mask plus __GFP_ZERO for allocating the page array Simplify this down to just use the pre-existing nested_gfp as-is for the page array allocation, and just the passed in gfp_mask for the page allocation, after conditionally ORing __GFP_HIGHMEM into it. This also makes the allocation warning a little more correct. Also initialize two variables at the time of declaration while touching this area.

README
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 Restructured Text 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.
