b8413fb1d5 Just cast the pointer to a uintptr_t then to the match bits, instead of abusing the ompi_ptr_t interface. Not critical for v1.2, as there are no portals platforms that are big endian, so the code in v1.2 will work well enough for now

27cea44a9c Fix a number of issues with the ompi_ptr_t:
* Make sure that the pval always writes to the correct portion of the
    lval.  This only matters on 32 bit big endian machines.
  * On 32 bit machines when assigning to pval, the other 4 bytes of lval
    weren't being written, which could lead to bogus data

We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes.  Refs trac:587

bfbc281e93 Fix slow startup issue with the MX MTL. The problem is caused by mx_connect() being a one-sided operation from the API level, but not being an interrupting call when the target is not entering the MX library. So if most of the processes exit mtl_mx_add_procs() and enter the stage gate 2 barrier, the other processes can only progress their mx_connect() calls when the targets enter the mx library. Because the event library is in EV_ONELOOP mode, this only happens once a second. The mx progress thread (hidden in the MX library) also only wakes up once a second, so mx_connect calls can take a second to complete.
The temporary solution is to switch into EV_NONBLOCK mode earlier (right after the mx_connect loop) so that there isn't a giant slowdown when processes enter the stage gate 2 barrier before other proesses.  They will now not block in the event library for any period of time, which appears to have a 50% speedup when running at > 64 procs.

882b429f64 ompi_mtl_datatype_pack is not a data-type function (really) so it still
need the free_after (which btw has a different meaning that the one removed
from the data-type engine few minutes ago).

126a68dc9a Big datatype commit. Remove all unused features of the datatype engine. As the memory
allocation logic is completely done outside the data-type engine (in the PML) there is
no need for any special case inside the data-type engine. There is less arguments for
the ompi_convertor_pack and ompi_convertor_unpack as well (the last field free_after is
not required anymore as there is no memory allocated in the engine itself). This change
affect all components using datatypes. I test most of them, but it might happens that I
miss some ... If it's the case please let me know (don't shoot the pianist!!).

688a16ea78 A long time waiting patch. Get rid of the comm->c_pml_procs. It was (and that was
long ago) supposed to be used as a cache for accessing the PML procs. But in
all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc.
This pointer can be accessed using the c_remote_group easily. Therefore, there is no
meaning of keeping the PML procs around. Slim fast commit ...

877b819ddb Initial commit of QLogic PSM MTL.
This provides support for the Infinipath interconnect using the PSM API. 

Of note: 
This version has a "hackaround" we always return 1 or greater from
the MTL PSM progress function, this should be examined further.

dfa1221c3b * AC_CONFIG_LINKS has a minor problem in that it always uses ln -s, rather
than $(LN_S).  This causes problems with with Windows and probably
  elsewhere (re: #200).  So use a slightly different trick to get the
  right header selected for the MEMCPY and TIMER components.

* Using the same trick used to solve the AC_CONFIG_LINKS problem, 
  stop using a separate header file for direct calling in the
  PML and MTL.  This lets me remove some icky code in ompi_mca.m4
  that was more fragile than I really liked.

6ed255f114 Substantial changes to the CM PML, allows us to have a very thin request for

reuse the pml_base_request_t as it was just too heavy for our needs. Lots of
code for 2/10 usec ;-)
