This patch series enable an accelerated AES/GCM stitched implementation
for Power10 or later 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):
  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.
  Update Kconfig and Makefile.
