#     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")
