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].
