The new generic VDSO library allows to unify the update_vsyscall[_tz]() implementations. Provide a generic implementation based on the x86 code and the bindings which need to be implemented in architecture specific code. [ tglx: Moved it into kernel/time where it belongs. Removed the pointless line breaks in the stub functions.
