SPARC64: UEK4 LDOMS DOMAIN SERVICES UPDATE 1

    This update provides several fixes for LDoms on UEK4
    (i.e. fixes/updates for the ldoms UEK4 port done previously
    - See BUG 21644721) and updates for ldoms to work with Zeus.
    It also provides support for libpri which requires a HV call
    to retrieve the PRI from the SP and enhancements to the vlds
    driver to allow multiple process to register/use a service
    simultaneously - so multiple processes can use libpri at the
    same time.
