This patch moves crypto_yield into internal.h as it's only used by internal code such as skcipher. It also adds a missing inclusion of sched.h which is required for cond_resched. The header files in internal.h have been cleaned up to remove some ancient junk and add some more specific inclusions. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
