Jeff Squyres afb33b8de8 Bring down upstream hwloc 438d9ed7457888c63d29778bda56cd27c52a8d51 to work around buggy NUMA node cpusets (i.e., buggy BIOSs). Thanks to Jeff Becker for reporting the issue. Submitted by Brice Goglin, reviewed by Jeff Squyres. cmr=v1.7.4:reviewer=ompi-rm1.7 This commit was SVN r30306.		2014-01-17 13:49:56 +00:00

Notes for hwloc component maintainers:

1. There can only be *1* hwloc version component at a time.
   Specifically: if there are multiple hwlocXYZ components (i.e.,
   different versions of hwloc), then they must all be .ompi_ignore'd
   except for 1.  This is because we currently m4_include all of the
   underlying hwloc's .m4 files -- if there are multiple hwlocXYZ
   components, I don't know if m4 will barf at the multiple,
   conflicting AC_DEFUNs, or whether it'll just do something
   completely undefined.

1a. As a consequence, if you're adding a new hwloc version component,
   you'll need to .ompi_ignore all others while you're testing the new
   one. 

2. If someone wants to fix #1 someday, we might be able to do what we
   do for libevent: OMPI_CONFIG_SUBDIR (instead of slurping in hwloc's
   .m4 files).
