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].

It is possible to build the series using the command below:
make -C tools/testing/selftests/ ARCH=<arch> TARGETS=vDSO CC=<compiler>
A version of the series rebased on 5.10-rc1 to simplify the testing can be found at [4].
