[PATCH v3 06/12] crypto: api - Allocate tfms from the secret pool

[sashiko-bot at kernel.org]

> A tfm's context holds the expanded key schedule, which a crash dump
> would capture.
> 
> Allocate tfms from the secret pool, so that their backing pages are
> marked by crash_memaction for the kdump kernel to wipe.
> The context is a flexible array at the end of struct crypto_tfm and the
> frontend's private data sits in front of the struct, so the whole
> allocation moves into the pool.
> 
> Allocation cost increases by a bucket lookup in crash_memaction. Freeing
> is unchanged.
