[PATCH v2 1/4] memblock tests: add user-provided arguments to Makefile

From: Rebecca Mckeever
Date: Wed Jun 22 2022 - 05:12:10 EST


Add VERBOSE and MEMBLOCK_DEBUG user-provided arguments. VERBOSE will
enable verbose output from Memblock simulator. MEMBLOCK_DEBUG will enable
memblock_dbg() messages.

Update the help message to include VERBOSE and MEMBLOCK_DEBUG. Update
the README to include VERBOSE. The README does not include all available
options and refers to the help message for the remaining options.
Therefore, omit MEMBLOCK_DEBUG from README.

A successful run produces no output. It is also possible to override different
-configuration parameters. For example, to simulate enabled NUMA, use:
