This series extends the kselftests for the vDSO library making sure: that they compile correctly on non x86 platforms, that they can be cross compiled and introducing new tests that verify the correctness of the library.
The so extended vDSO kselftests have been verified on all the platforms supported by the unified vDSO library [1].
The only new patch that this series introduces is the first one, patch 2 and patch 3 have already been reviewed in past as part of other series [2] [3].
