[PATCH 07/28] crypto: ahash: increase the maximum allowed statesize

[Tero Kristo]

The statesize is used to determine the maximum size for saved ahash
context. In some cases, this can be much larger than what is currently
allocated for it, for example omap-sham driver uses a buffer size of
PAGE_SIZE. Increase the statesize to accommodate this.
