35 * These functions MUST NOT use any vector registers for parameters or
36 * results -- the caller is compiled with -mno-sse &c. in the kernel,
37 * and dynamically turns on the vector unit just before calling them.
38 * Internal subroutines that use the vector unit for parameters are
39 * declared in aes_ssse3_impl.h instead.
