  Enhancement:
  For z/VM 6.2, z/VM 6.4 HCM, this APAR offers:
  1. Support of a new attribute for PCIe functions called PCIe UID
   on the appropriate processor types:
   - 2964-N30,-N63,-N96,-NC9,-NE1
   - 2964-L30,-L63,-L96,-LC9,-LE1
   - 2965-N10,-N20
   - 2965-L10,-L20
  
  2. The PCIe UID is combined with a new partition attribute PCIe
  UID uniqueness checking flag.
  A PCIe function can be accessible by more than one partition
  through its access and candidate lists:
   - To partitions with UID=NO, meaning that UID checking for
     the partition is disabled, you can assign PCIe functions
     with any UID value, even duplicated ones. Specifying a UID
     for these functions is optional.
   - To partitions with UID=YES, meaning that UID checking for
     the partition is enable, you can assign only PCIe function
     that have a UID defined and all UIDs need to be unique in
     the scope of that partition.
   - For a processor, you can have a mix of partitions with and
     without UID checking.
  
  3. HCM supports creating multiple-PCIe functions in one step.

  To support LinuxONE and above features,
  it is recommended to install first the HCD PTFs for
  APAR VM65827. About APAR VM65827 details,
  please reference to HCD APAR information.
