Hi Ard,
Apologies for the non-follow-up - couldn't find the original patch.
Your patch "crypto: ccm - switch to separate cbcmac driver" causes a
BUG_ON when virtual stacks are used, in crypto_ccm_auth() is called,
because you put odata/idata on the stack. What's going on there? I
thought we knew we can't do that? Did I miss something?
