We tried doing an RC2 built without updating the greek,
and found where that failed in build automation.
Reving again for rc3, as we've already applied the rc2 tag.

* Additionally, fixes the `NULL` option to `OMPI_MCA_plm_rsh_agent`
would would also lead to a segv. Now it operates as intended by
disqualifying the `rsh` component and falling back onto the `isolated`
component.

This PR removes the constant defining the max attachment address and
replaces it with the largest address that shows up in /proc/self/maps.
This should address issues found on AARCH64 where the max address
may differ based on the configuration.
Since the calculated max address may differ between processes the
max address is sent as part of the modex and stored in the endpoint
data.

This commit fixes an issue discovered in the XPMEM registration cache. It
was possible for a registration to be invalidated by multiple threads
leading to a double-free situation or re-use of an invalidated registration.
This commit fixes the issue by setting the INVALID flag on a registation
when it will be deleted. The flag is set while iterating over the tree
to take advantage of the fact that a registration can not be removed
from the VMA tree by a thread while another thread is traversing the VMA
tree.

There are cases where the same interval may be in the tree multiple
times. This generally isn't a problem when searching the tree but
may cause issues when attempting to delete a particular registration
from the tree. The issue is fixed by breaking a low value tie by
checking the high value then the interval data.
If the high, low, and data of a new insertion exactly matches an
existing interval then an assertion is raised.

Until now sqrt(n) was missed as a factor for odd square numbers n. This
lead to suboptimal results of MPI_Dims_create for input numbers like 9,
25, 49, ... Fix the results by including sqrt(n) in the search for
factors.

(cherry picked from commit 441bad9a75)
This patch fixes#7147 by preventing overflow when multiplying
the count and the blocklen. The count reflects MPI count and is
therefore bound to the size of an int (it is an uint32_t) while the
blocklen can be merged together to represent the largest contiguous
memory layout and it is therefore promoted to a size_t.

Allow the user to override the modulefile_path (root directory to
install the Open MPI modulefile), even if install_in_opt==1. For
example:
rpmbuild \
--rebuild \
--define 'install_in_opt 1' \
--define 'modulefile_path /path/to/my/modulefiles/openmpi/%{version}' \

When the provider does not support FI_REMOTE_CQ_DATA, the OFI tag does not have
sizeof(int) bits for the rank. Therefore, unexpected behavior will occur when
this limit is crossed.
Check the max allowed number of ranks during add_procs() and return if there is
danger of exceeding this threshold.

Clarify in README what --with-hwloc does in its different use cases.
Also, ensure that the behavior when specifying `--with-hwloc` is the
same as if that option is not specified at all. This is what we did
in Open MPI <= v3.x; looks like we inadvertantly caused `--with-hwloc`
to be synonymous with `--with-hwloc=external` in v4.0.0.
