use GFP_ATOMIC when necessary; use atomic_t when allocating

why?
You mean why are atomics required? Yes that is a good question.
Yep. the commit message isn't explaining why, just what :)
In honouring requests that don't have the CRYPTO_TFM_REQ_MAY_SLEEP
set,
afaict, it's the standard non-wait variant GFP that drivers use (see
the ixp4xx driver for e.g.).
so GFP_ATOMIC and atomic_t aren't related. I can understand the need
for GFP_ATOMIC, but I don't get why something needs to be declared
atomic_t.
