Linus Torvalds f21f7b5162 Update to the VDSO subsystem:
- Make the handling of compat functions consistent and more robust
 
      - Rework the underlying data store so that it is dynamically
        allocated, which allows the conversion of the last holdout SPARC64
        to the generic VDSO implementation
 
      - Rework the SPARC64 VDSO to utilize the generic implementation
 
      - Mop up the left overs of the non-generic VDSO support in the core
        code.
 
      - Expand the VDSO selftest and make them more robust
 
      - Allow time namespaces to be enabled independently of the generic
        VDSO support, which was not possible before due to SPARC64 not
        using it.
 
      - Various cleanups and improvements in the related code.
