During initialization of a signal testcase, features declared as required
are properly checked against the running system but no action is then taken
to effectively skip such a testcase.
Fix core signals test logic to abort initialization and report such a
testcase as skipped to the KSelfTest framework.

kselftest/arm64: signal: Add test case for SVE register state in signals2021-08-23T10:11:05+00:00Mark Brownbroonie@kernel.org2021-08-19T13:42:44+00:00urn:sha1:5262b216f4a97f4e2f517dba296a3cad4bc42bab
Currently this doesn't actually verify that the register contents do the
right thing, it just verifes that a SVE context with appropriate size
appears.

We do not support changing the SVE vector length as part of signal return,
verify that this is the case if the system supports multiple vector lengths.

As a basic check that the SVE signal frame is being set up correctly
verify that the vector length in the signal frame is the vector length
that the process has.

kselftest/arm64: signal: Support signal frames with SVE register data2021-08-23T10:11:04+00:00Mark Brownbroonie@kernel.org2021-08-19T13:42:41+00:00urn:sha1:ace19b1845a5c2906d59f6358b80ed687b52b2cd
A signal frame with SVE may validly either be a bare struct sve_context or
a struct sve_context followed by vector length dependent register data.
Support either in the generic helpers for the signal tests, and while we're
at it validate the SVE vector length reported.

Allow testcases for SVE signal handling to flag the dependency and be
skipped on systems without SVE support.

The PAC tests check to see if the system supports the relevant PAC features
but instead of skipping the tests if they can't be executed they fail the
tests which makes things look like they're not working when they are.

kselftest/arm64: mte: Fix misleading output when skipping tests2021-08-20T10:11:05+00:00Mark Brownbroonie@kernel.org2021-08-19T17:29:02+00:00urn:sha1:83e5dcbece4ea67ec3ad94b897e2844184802fd7
When skipping the tests due to a lack of system support for MTE we
currently print a message saying FAIL which makes it look like the test
failed even though the test did actually report KSFT_SKIP, creating some
confusion. Change the error message to say SKIP instead so things are
clearer.
