#[target_feature(enable = "kl")]
pub unsafe fn _mm_encodekey256_u32(key_params: u32, key_lo: __m128i, key_hi: __m128i, handle: *mut u8) -> u32Wrap a 256-bit AES key into a 512-bit key handle and stores it in handle. Returns the control
parameter used to create the IWKey.
key_params[0]: If set, this key can only be used by the Kernel.key_params[1]: If set, this key can not be used to encrypt.key_params[2]: If set, this key can not be used to decrypt.key_params[31:3]: Reserved for future use, must be set to0.
Note that these restrictions need hardware support, and the supported restrictions can be found by
calling __cpuid(0x19) and checking the EAX[0:2] bits. Failing to follow these restrictions may
result in a General Protection Exception.
