    nds32: Fix vDSO clock_getres() · af9abd65
    Vincenzo Frascino authored
    clock_getres in the vDSO library has to preserve the same behaviour
    of posix_get_hrtimer_res().
    
    In particular, posix_get_hrtimer_res() does:
        sec = 0;
        ns = hrtimer_resolution;
    and hrtimer_resolution depends on the enablement of the high
    resolution timers that can happen either at compile or at run time.
    
    Fix the nds32 vdso implementation of clock_getres keeping a copy of
    hrtimer_resolution in vdso data and using that directly.
