35 1.2 riastrad * These functions MUST NOT use any vector registers for parameters or
36 1.2 riastrad * results -- the caller is compiled with -mno-sse &c. in the kernel,
37 1.2 riastrad * and dynamically turns on the vector unit just before calling them.
38 1.2 riastrad * Internal subroutines that use the vector unit for parameters are
39 1.2 riastrad * declared in aes_sse2_impl.h instead.
