Add checks for memblock_alloc_try_nid for bottom up allocation direction.
As the definition of this function is pretty close to the core
memblock_alloc_range_nid, the test cases implemented here cover most of
the code paths related to the memory allocations.
The tested scenarios are:
- Region can be allocated within the requested range (both with aligned
and misaligned boundaries)
- Region can be allocated between two already existing entries
- Not enough space between already reserved regions
- Memory at the range boundaries is reserved but there is enough space
to allocate a new region
- The memory range is too narrow but memory can be allocated before
the maximum address
- Edge cases:
+ Minimum address is below memblock_start_of_DRAM()
+ Maximum address is above memblock_end_of_DRAM()
Add test case wrappers to test both directions in the same context.

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.
