parentcrypto: ahash - Use GFP_KERNEL in unaligned setkey (diff)
crypto: ahash - Add unaligned handling and default operations
This patch exports the finup operation where available and adds a default finup operation for ahash. The operations final, finup and digest also will now deal with unaligned result pointers by copying it. Finally export/import operations are will now be exported too.
