#     Pull timekeeping updates from Thomas Gleixner:
#      "A set of timekeeping/VDSO updates:
#     
#        - Preparatory work to allow S390 to switch over to the generic VDSO
#          implementation.
#     
#          S390 requires that the VDSO data pointer is handed in to the
#          counter read function when time namespace support is enabled.
#          Adding the pointer is a NOOP for all other architectures because
#          the compiler is supposed to optimize that out when it is unused in
#          the architecture specific inline. The change also solved a similar
#          problem for MIPS which fortunately has time namespaces not yet
#          enabled.
#     
#          S390 needs to update clock related VDSO data independent of the
#          timekeeping updates. This was solved so far with yet another
#          sequence counter in the S390 implementation. A better solution is
#          to utilize the already existing VDSO sequence count for this. The
#          core code now exposes helper functions which allow to serialize
#          against the timekeeper code and against concurrent readers.
#     
#          S390 needs extra data for their clock readout function. The initial
#          common VDSO data structure did not provide a way to add that. It
#          now has an embedded architecture specific struct embedded which
#          defaults to an empty struct.
#     
#          Doing this now avoids tree dependencies and conflicts post rc1 and
#          allows all other architectures which work on generic VDSO support
#          to work from a common upstream base.
#     
#        - A trivial comment fix"
