Technically it *can*, but you'll then have to be responsible for dealing with all the extra register save/restores for context switches. Normal wisdom is that it's just not worth that cost unless you're doing an extended amount of such code (e.g. RAID block checksums using Neon).
I've always thought that all the crypto stuff in the kernel just *begs* to be vectorized -and should be, IMHO. But that's a lot of work, admittedly.
