For consistency with __vdso_clock_gettime64() there should also be a 64-bit variant of clock_getres(). 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.

Please merge this along with the 32-bit Arm change, as it doesn't make sense otherwise.
