crypto: vmx - Improved AES/XTS performance of 6-way unrolling for ppc
Improve AES/XTS performance of 6-way unrolling for PowerPC up
to 17% with tcrypt. This is done by using one instruction,
vpermxor, to replace xor and vsldoi.
The same changes were applied to OpenSSL code and a pull request was
submitted.
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.
