[PATCH] crypto: ahash - Use GFP_KERNEL on allocation if the request can sleep

[Steffen Klassert <steffen.klassert@secunet.com>]

ahash_op_unaligned() and ahash_def_finup() allocate memory atomically,
regardless whether the request can sleep or not. This patch changes
this to use GFP_KERNEL if the request can sleep.
