The constify plugin will automatically constify a class of types that contain
only function pointers. The icp structs fail to build if this is enabled with
the following error. The no_const attribute makes the plugin skip those
structs.
module/icp/spi/kcf_spi.c: In function ‘copy_ops_vector_v1’:
module/icp/spi/kcf_spi.c:61:16: error: assignment of read-only location ‘*dst_ops->cou.cou_v1.co_control_ops’

A port of the Illumos Crypto Framework to a Linux kernel module (found
in module/icp). This is needed to do the actual encryption work. We cannot
use the Linux kernel's built in crypto api because it is only exported to
GPL-licensed modules. Having the ICP also means the crypto code can run on
any of the other kernels under OpenZFS. I ended up porting over most of the
internals of the framework, which means that porting over other API calls (if
we need them) should be fairly easy. Specifically, I have ported over the API
functions related to encryption, digests, macs, and crypto templates. The ICP
is able to use assembly-accelerated encryption on amd64 machines and AES-NI
instructions on Intel chips that support it. There are place-holder
directories for similar assembly optimizations for other architectures
(although they have not been written).
