- Ensure that the CLOCK_AUX base calculations are properly scaled against
the base timekeeper. The update function failed to take the fractional
nanosecond part into account, which results in a rounding error.
- Cleanup and consolidate the vsyscall headers to get rid of pointless
copies all over the architectures.
- Replace a runtime conditional in the time getter function for namespaced
clocks by simple pointer arithmetic which speeds up the read function.

Pull VDSO updates from Thomas Gleixner:
"Updates for the VDSO subsystem:
- Ensure that the CLOCK_AUX base calculations are properly scaled
against the base timekeeper. The update function failed to take the
fractional nanosecond part into account, which results in a
rounding error.
- Cleanup and consolidate the vsyscall headers to get rid of
pointless copies all over the architectures.
- Replace a runtime conditional in the time getter function for
namespaced clocks by simple pointer arithmetic which speeds up the
read function"
