note:
in order to keep this commit easy to review, some AS_IF([...]) were replaced with
AS_IF([false], ...) or AS_IF_([true], ...)
these will be removed and re-idented in a subsequent commit
This fixes https://github.com/open-mpi/ompi/issues/1732: i.e., the
case where the outer project has its own check for
<valgrind/valgrind.h>, but also supplements CPPFLAGS (to find
Valgrind's header files) before doing that check.

Ideally, we would tell OMPI to disable autoconf's caching of our
valgrind check result so that its check gets the right result after
adding CPPFLAGS. Not sure if we can do that.
For now, just disable our Valgrind code in embedded mode.
This will keep the x86 backend enabled under Valgrind but
it will auto-disable itself when finding identical APIC ids anyway
(because CPUID returns same outputs for all PUs).

(cherry picked from commit open-mpi/hwloc@8b44fb1c81)
Remove contrib/windows/
Merge hwlocXYZ/hwloc/README-ompi.txt back into hwlocXYZ/README-ompi.txt instead of having both.
Add README.txt in new automake-required directory contrib/systemd/
Keep the following patches applied since they are not in 1.11.3
linux: actually enable libudev based on the result of AC_CHECK_LIB
(cherry picked from open-mpi/hwloc@9549fd59af)
configure: check the actual may_alias syntax that we use
(cherry picked from open-mpi/hwloc@0ab7af5e90)
WRAPPER_EXTRA flags are checked *before* the POST_CONFIG macro is
invoked. So set them in the main CONFIG macro.

xlc 13.1.0 crashes because of our may_alias attributes in nolibxml.c
on Power7. libxml.c and nolibxml.c are the only may_alias users for now,
so change our configure check to match the actual code using it.
Thanks to Paul Hargrove for reporting and debugging the issue,
and providing the patch.

instead of doing AC_CHECK_HEADERS+AC_CHECK_LIB and only using the result of the former.
Thanks to Paul Hargrove for reporting the issue (OMPI build with -m32).

Define OPAL_MAXHOSTNAMELEN to be either:
(MAXHOSTNAMELEN + 1) or
(limits.h:HOST_NAME_MAX + 1) or
(255 + 1)
For pmix code, define above using PMIX_MAXHOSTNAMELEN.
Fixup opal layer to use the new max.

when SMT is enabled, a core must be counted as long as one of its hwthread is allowed
Thanks Ben Menadue for the report.
This fixes a regression from open-mpi/ompi@6d149554a7
setmntent() doesn't support root_fd, but manual parsing of
/proc/mounts is fragile, and actually buggy for very long mount lines
(see open-mpi/hwloc#142 (comment)).
Since we only openat("/proc/mounts") there, just manually concatenate
the fsroot_path and use setmntent().
Thanks to Nathan Hjelm for the report.

Otherwise libpciaccess sends a big error message to stderr:
Error opening /devices/pci@0,0:reg: Permission denied
(cherry picked from commit open-mpi/hwloc@d93c7c0960)
The OPAL_PROC_ON_* definitions have been changed from values to
flags. This should not cause any problems as these values were already
used as flags throughout the code base. Note, there will be a
difference between localities produced by the new code and the
old. For example, if a machine does not have a level-3 but two cores
share a level-1 or level-2 cache cache the level-3 bit will not be set
in the locality and OPAL_PROC_ON_LOCAL_L3CACHE will return 0. Before
this change it would have returned 1.
In addition the OPAL_PROC_ON_LOCAL_* macros have been simplified.

This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).

linux: only use the device-tree on Power machines
It's available on ARM but the assumption that cpus' "reg" start at 0
is invalid.
We could make that work but the device-tree doesn't currently
bring anything better than sysfs on ARM, so don't bother for now.
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.
All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.
