Andre Przywara 92dbc74464 kselftest/arm64: signal: fix/refactor SVE vector length enumeration ... [ Upstream commit 5225b6562b ] Currently a number of SVE/SME related tests have almost identical functions to enumerate all supported vector lengths. However over time the copy&pasted code has diverged, allowing some bugs to creep in: - fake_sigreturn_sme_change_vl reports a failure, not a SKIP if only one vector length is supported (but the SVE version is fine) - fake_sigreturn_sme_change_vl tries to set the SVE vector length, not the SME one (but the other SME tests are fine) - za_no_regs keeps iterating forever if only one vector length is supported (but za_regs is correct) Since those bugs seem to be mostly copy&paste ones, let's consolidate the enumeration loop into one shared function, and just call that from each test. That should fix the above bugs, and prevent similar issues from happening again.
