This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux release.  Product Management has
requested further review of this request by Red Hat Engineering, for
potential inclusion in a Red Hat Enterprise Linux release for currently
deployed products.  This request is not yet committed for inclusion in
a release.

patch in the works for some of this (the missing facts is caused by an assumption when/where /proc/sysinfo exists on these platforms, resulting the "normal" socket counting getting skipped for some of these cases).

in master:

    978466: fix missing socket info s390x/ppc64
    
    Try to better handle system with no topology info
    
    s390/ppc sometimes have pretty limited cpu topology
    info available, especially on rhel5. Try to handle
    those cases.
    
    On s390x systems, that have a "cpu topology" info in
    /proc/sysinfo and populated
    /sys/devivces/system/cpu/cpu*/topology, we defer to
    the latter. This is the scenario for s390x on zvm
    running RHEL6.
    
    Systems running RHEL5 will not have the /sys info
    populated, so fall back to the /proc/sysinfo in
    those cases.
    
    For RHEL5 ppc64 systems with no /sys cpu topology
    exposed, attempt to check cpu/cpuN/physical_id
    for topology info.
    
    If that doesn't have useful info, fallback
    to 1 thread = 1 cpu = 1 core = 1 socket
    
    Added cpu_t.topology_source fact to track how
    client determined cpu topology info.
