powerpc: Fix vDSO clock_getres() # # 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 powerpc vdso implementation of clock_getres keeping a copy of # hrtimer_resolution in vdso data and using that directly. # # Fixes: a7f290dad32e ("[PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernel") # Cc:
