Subject: [PATCH v2 0/3] kselftest/arm64: Update sve-ptrace for ABI changes

Mark Rutland's recent SME fixes updated the SME ABI to reject any
attempt to write FPSIMD register data via the streaming mode SVE
register set but did not update the sve-ptrace test to take account of
this, resulting in spurious failures.  Update the test for this, and
also fix another preexisting issue I noticed while looking at this.
