Subject: [PATCH v3 0/6] crypto: Accelerated AES/GCM stitched implementation

This patch series enable an accelerated AES/GCM stitched implementation for
Power10+ CPU(ppc64le).  This module supports AEAD algorithm.  The stitched
implementation provides 3.5X+ better performance than the baseline.

This patch has been tested with the kernel crypto module tcrypt.ko and has
passed the selftest.  The patch is also tested with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled.

Danny Tsen (6):
  Update Kconfig and Makefile.
  Glue code for AES/GCM stitched implementation.
  An accelerated AES/GCM stitched implementation.
  Supporting functions for AES.
  Supporting functions for ghash.
  A perl script to process PowerPC assembler source.
