a9dc38def4 Create an empty stdint.h for arm_neon.h to include.
The armv8crypto module includes arm_neon.h for the compiler intrinsic
functions. This includes the userland stdint.h file that doesn't exist in
the kernel. Fix this by providing an empty stdint.h to be used when we
include arm_neon.h.

d6699d292b Add accelerated AES with using the ARMv8 crypto instructions. This is based
on the AES-NI code, and modified as needed for use on ARMv8. When loaded
the driver will check the appropriate field in the id_aa64isar0_el1
register to see if AES is supported, and if so the probe function will
signal the driver should attach.

With this I have seen up to 2000Mb/s from the cryptotest test with a single
thread on a ThunderX Pass 2.0.
