- Update to 1.2.16
 * The drmgr command does not currently allow users to specify the 
    drc index of the resource they wish to add/remove. This patch 
    updates the drmgr command so that users can specify either a 
    drc name or a drc index with the -s option.
    
 * This functionality is needed for the upcoming userspace handling 
    of PRRN RTAS events. The rtas_errd will already have the drc 
    index for the resources it needs, adding the capability to 
    parse drc names from the device tree is not supported in 
    rtas_errd though.
 * Update the man page for update_flash which had an out of date link
    to instructions for resetting a managed system to a non-partitioned
    configuration.
 * The upstream kernel has a feature in the pseries PCI code called DDW
    that inserts TCEs transparently to device drivers. The upstream kernel
    was recently sent a fix for DLPAR that ensured those TCEs would get
    cleared upon DLPAR remove (http://patchwork.ozlabs.org/patch/213735/),
    but for it to work, we need a corresponding change to drmgr for, at
    least, PHB remove, so that the notifier chain has fired before we call
    into the slot isolate code. Without such a change, there is no way to
    ensure the DDW TCEs are cleared, and the DLPAR will always fail.
 * Add and use dt_swap_int() to byte swap on little endian.
    
 * Also declare buf as unsigned char, so that we don't sign extend when
    printing values from it. (forwarded request 156267 from k0da)
