Add function setup_numa_memblock() for setting up a memory layout with
multiple NUMA nodes in a previously allocated dummy physical memory.
This function can be used in place of setup_memblock() in tests that need
to simulate a NUMA system.
setup_numa_memblock():
- allows for setting up a memory layout by specifying the fraction of
MEM_SIZE in each node
Set CONFIG_NODES_SHIFT to 4 when building with NUMA=1 to allow for up to
16 NUMA nodes.

memblock tests: change build options to run-time options2022-07-20T07:46:33+00:00Rebecca Mckeeverremckee0@gmail.com2022-07-14T03:17:17+00:00urn:sha1:06c8580aa23ddc9b1c37b9c7c5e2cc504e460207
Change verbose and movable node build options to run-time options.
Movable node usage:
$ ./main -m
Or:
$ ./main --movable-node
Verbose usage:
$ ./main -v
Or:
$ ./main --verbose

memblock tests: Makefile: add arguments to control verbosity2022-07-04T16:58:27+00:00Rebecca Mckeeverremckee0@gmail.com2022-07-04T04:06:55+00:00urn:sha1:946dccb35d74079436677afcdc767d0406e99a88
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.

memblock tests: Fix testing with 32-bit physical addresses2022-03-05T17:46:46+00:00Karolina Drobnikkarolinadrobnik@gmail.com2022-03-04T12:52:49+00:00urn:sha1:2a7ceac9e58167fadc3496c5f694543d4bbe03ef
Building memblock simulator on x86_64 with 32BIT_PHYS_ADDR_T=1
produces "cast to pointer from integer of different size" warnings.
Fix them by building the binary in 32-bit environment when using
32-bit physical addresses.
