This will allow the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and finally the removal of 32-bit time types from the kernel and UAPI. The generic vDSO library already provides nearly all necessary building blocks for architectures to provide this function. Only a prototype is missing. Add the prototype to the generic header so architectures can start providing this function.
