Per the devel mailing list, we discussed the need/desirability of this change. Here is the logic behind not including it:
If you call "hwloc_topology_load", then hwloc merrily does its discovery and slams many-core systems. If you call "opal_hwloc_get_topology", then that is fine - it checks if we already have it, tries to get it from PMIx (using shared mem for hwloc 2.x), and only does the discovery if no other method is available.
We previously decided to let those who need the topology call "opal_hwloc_get_topology" to ensure the topo was available so that we don't load it unless someone actually needs it - in the case where it isn't available via PMIx, this avoids paying the startup time and memory footprint penalties for no reason. The function is protected so it will simply return SUCCESS if the topology is already defined.
After discussion, it was decided to stick with that "only setup the topology if someone actually needs it" approach. Hence, we will not blanket init the topology, and the mtl/ofi component will call opal_hwloc_get_topology to ensure the topo has been defined prior to using it.

The fence logic in MPI_Init got messed up somehow such that we were
always executing a fence, which is not desirable. The logic is supposed
to be:
* if async fence is requested and we are not collecting data, then do
not fence at all
* if async fence is requested and we are collecting data, then execute
the fence in the background - wait for completion at the end of MPI_Init.
* if async fence is not requested, then execute a blocking fence at that
point, collecting data as directed. Note that we cannot actually do a
blocking fence as we need to cycle the event library via opal_progress
as the PMIx progress thread is tied to the OMPI event base.

If the user however subsequently calls MPI_File_write_shared or similar operations, an error

If someone gives us a namespace that doesn't easily translate to an
integer, we have to create a mechanism for working around the
disconnect. PRRTE has been updated to give us a flag so we know we were
"natively" launched. If we don't see it, then fall back to generating a
hash of the nspace as our jobid. We then have to translate back/forth
between nspace and jobid using a lookup table.
Probably not the right long-term solution, but hopefully helps get us
thru for a bit.

This commit addresses two issues in osc/rdma:
1) It is erroneous to attach regions that overlap. This was being
allowed but the standard does not allow overlapping attachments.
2) Overlapping registration regions (4k alignment of attachments)
appear to be allowed. Add attachment bases to the bookeeping
structure so we can keep better track of what can be detached.
It is possible that the standard did not intend to allow #2. If that
is the case then #2 should fail in the same way as #1. There should
be no technical reason to disallow #2 at this time.

Automake's Fortran compilation rules inexplicably use CPPFLAGS and
AM_CPPFLAGS. Unfortunately, this can cause problems in some cases
(e.g., picking up already-installed mpi.mod in a system-default
include search path).
So in relevant module-using Fortran compilation Makefile.am's, zero
out CPPFLAGS and AM_CPPFLAGS.
This has a side-effect of requiring that we compile the one .c file in
the F08 library in a new, separate subdirectory (with its own
Makefile.am that does _not_ have CPPFLAGS/AM_CPPFLAGS zeroed out).

Fix the C types for the following:
* MPI_UNWEIGHTED
* MPI_WEIGHTS_EMPTY
* MPI_ARGV_NULL
* MPI_ARGVS_NULL
* MPI_ERRCODES_IGNORE
There is lengthy discussion on
https://github.com/open-mpi/ompi/pull/7210 describing the issue; the
gist of it is that the C and Fortran types for several MPI global
sentenial values should agree (specifically: their sizes must(**)
agree). We erroneously had several of these array-like sentinel
values be "array-like" values in C. E.g., MPI_ERRCODES_IGNORE was an
(int *) in C while its corresponding Fortran type was "integer,
dimension(1)". On a 64 bit platform, this resulted in C expecting the
symbol size to be sizeof(int*)==8 while Fortran expected the symbol
size to be sizeof(INTEGER, DIMENSION(1))==4.
That is incorrect -- the corresponding C type needed to be (int).
Then both C and Fortran expect the size of the symbol to be the same.
(**) NOTE: This code has been wrong for years. This mismatch of types
typically worked because, due to Fortran's call-by-reference
semantics, Open MPI was comparing the *addresses* of these instances,
not their *types* (or sizes) -- so even if C expected the size of the
symbol to be X and Fortran expected the size of the symbol to be Y
(where X!=Y), all we really checked at run time was that the addresses
of the symbols were the same. But it caused linker warning messages,
and even caused errors in some cases.
Specifically: due to a GNU ld bug
(https://sourceware.org/bugzilla/show_bug.cgi?id=25236), the 5 common
symbols are incorrectly versioned VER_NDX_LOCAL because their
definitions in Fortran sources have smaller st_size than those in
libmpi.so.
This makes the Fortran library not linkable with lld in distributions
that ship openmpi built with -Wl,--version-script
(https://bugs.llvm.org/show_bug.cgi?id=43748):
% mpifort -fuse-ld=lld /dev/null
ld.lld: error: corrupt input file: version definition index 0 for symbol
mpi_fortran_argv_null_ is out of bounds
>>> defined in /usr/lib/x86_64-linux-gnu/openmpi/lib/libmpi_usempif08.so
...
If we fix the C and Fortran symbols to actually be the same size, the
problem goes away and the GNU ld bug does not come into play.
This commit also fixes a minor issue that MPI_UNWEIGHTED and
MPI_WEIGHTS_EMPTY were not declared as Fortran arrays (not fully fixed
by commit 107c0073dd).

Make sure to get an RDM provider that can provide both local and

example.
Add OPAL_CHECK_OFI_VERSION_GE() m4 macro to check that the Libfabric
we're building against is >= a target version. Use this check in two
places:
1. MTL/OFI: Make sure it is >= v1.5, because the FI_LOCAL_COMM /
FI_REMOTE_COMM constants were introduced in Libfabric API v1.5.
2. BTL/usnic: It already had similar configury to check for Libfabric
>= v1.1, but the usnic component was checking for >= v1.3. So
update the btl/usnic configury to use the new macro and check for
>= v1.3.
