2019-05-16nds32: Fix vDSO clock_getres()Vincenzo Frascino
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.

2018-02-22nds32: VDSO supportGreentime Hu
This patch adds VDSO support. The VDSO code is currently used for sys_rt_sigreturn() and optimised gettimeofday() (using the SoC timer counter). Signed-off-by: Vincent Chen <vincentc@andestech.com> Signed-off-by: Greentime Hu <greentime@andestech.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
