Re: [PATCH] mac80211: aes_ccm: move struct aead_req off the stack

So use kzalloc

Do we really need kzalloc()? We have things on the stack right now, and
don't initialize, so surely we don't really need to zero things?

This only addresses one half of the problem. The other problem, i.e.,
the fact that the aad[] array lives on the stack of the caller, is
handled adequately imo by the change proposed by Johannes.

But if we allocate things anyway, is it worth expending per-CPU buffers
on these?
