Andrew Donnellan 16e5d74e12 lib/test_meminit: allocate pages up to order MAX_ORDER
commit efb78fa86e95832b78ca0ba60f3706788a818938 upstream.

test_pages() tests the page allocator by calling alloc_pages() with
different orders up to order 10.

However, different architectures and platforms support different maximum
contiguous allocation sizes.  The default maximum allocation order
(MAX_ORDER) is 10, but architectures can use CONFIG_ARCH_FORCE_MAX_ORDER
to override this.  On platforms where this is less than 10, test_meminit()
will blow up with a WARN().  This is expected, so let's not do that.

Replace the hardcoded "10" with the MAX_ORDER macro so that we test
allocations up to the expected platform limit.

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.
