Hi Vincento, I've implemented now what I tried to explain earlier. This moves the implementation of clock_gettime() and clock_getres() over to 64-bit __kernel_timespec, with a conversion in the end for architectures that actually use the 32-bit calls. The vdso/types.h file is now obsolete, but we do need to duplicate a few functions on mips32 and x86-32. It may be possible to fold those into the generic lib/vdso/gettimeofday.c file as another step. If there are no objections, please fold these changes into your series.
