Currently for order-0 pages we use a bulk-page allocator to get set of pages. From the other hand not allocating all pages is something that might occur. In that case we should fallbak to the single-page allocator trying to get missing pages, because it is more permissive(direct reclaim, etc). Introduce a vm_area_alloc_pages() function where the described logic is implemented.

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.
