This series is a combination of factoring out some duplicated code and a
very minor optimisation to the performance of handling converting FPSIMD
state to SVE in the live registers for 128 bit SVE vectors.

Mark Brown (3):
  arm64/sve: Split _sve_flush macro into separate Z, P and FFR flushes
  arm64/sve: Use the sve_flush macros in sve_load_from_fpsimd_state()
  arm64/sve: Skip flushing Z registers with 128 bit vectors
