Subject: [PATCH 0/3] kselftest/arm64: Fixes for fp-ptrace on SME only
 systems

When testing SME only systems I noticed that fp-ptrace does not cope at
all well with them, this series fixes the major issues so that the test
program completes successfully.  The reason I was looking at this is
that following the recent round of fixes to ptrace we do not currently
offer any mechanism for disabling streaming mode via ptrace, this series
brings the program to a point where it tests the currently implemented
ABI.  A further series allowing the disabling of streaming mode via
ptrace will follow.
