Re: [PATCH v5 0/4] kselftest/arm64: Vector length configuration tests

Currently we don't have full automated tests for the vector length
configuation ABIs offered for SVE, we have a helper binary for setting
the vector length which can be used for manual tests and we use the
prctl() interface to enumerate the vector lengths but don't actually
verify that the vector lengths enumerated were set.

This patch series provides a small helper which allows us to get the
currently configured vector length using the RDVL instruction via either
a library call or stdout of a process and then uses this to both add
verification of enumerated vector lengths to our existing tests and also
add a new test program which exercises both the prctl() and sysfs
interfaces.

Applied to arm64 (for-next/kselftest), thanks!
