Pull vdso updates from Thomas Gleixner:

- 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

timens: Remove dependency on the vDSO

Previously, missing time namespace support in the vDSO meant that time
namespaces needed to be disabled globally. This was expressed in a hard
dependency on the generic vDSO library. This also meant that architectures
without any vDSO or only a stub vDSO could not enable time namespaces.
Now that all architectures using a real vDSO are using the generic library,
that dependency is not necessary anymore.

Remove the dependency and let all architectures enable time namespaces.
