[v2,0/3] kselftest/arm64: Test ptrace writing via FPSIMD and reading via SVE

Message

This series has a couple of minor fixes and cleanups for sve-ptrace plus
the addition of a new test which validates that we can write using the
FPSIMD regset and then read matching data back using the SVE regset -
previously we only validated writing SVE and reading FPSIMD data.

v2
 - Rebase onto v5.18-rc1

Mark Brown (3):
  kselftest/arm64: Fix comment for ptrace_sve_get_fpsimd_data()
  kselftest/arm64: Remove assumption that tasks start FPSIMD only
  kselftest/arm64: Validate setting via FPSIMD and read via SVE regsets
