CONFIG_GENERIC_GETTIMEOFDAY requires CONFIG_GENERIC_TIME_VSYSCALL, but
that's not expressed anywhere. This stuff has grown too many config
options over time:

GENERIC_TIME_VSYSCALL, HAVE_GENERIC_VDSO, GENERIC_VDSO_DATA_STORE

All architectures except SPARC64 use the generic code and the generic
VDSO data store implementation. That config maze wants to be
consolidated.
