[PATCH v2 00/15] vDSO: header file cleanups

[Thomas Weißschuh]

The vDSO header files are a bit of a mess, relying on transitive
includes and pulling in much more definitions than necessary.

Clean up the headers and remove some ifdeffery in the rng core.

This was originally part of my SPARC generic vDSO patch series [0].
After feedback I am reworking that series and it may not require these
cleanups anymore. But as the code is already written I am submitting it
here standalone.

Based on tip/timers/vdso.
