2008-01-11[CRYPTO] api: Include sched.h for cond_resched in scatterwalk.hHerbert Xu1-0/+1
As Andrew Morton correctly points out, we need to explicitly include sched.h as we use the function cond_resched in crypto/scatterwalk.h. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-01-11[CRYPTO] scatterwalk: Restore custom sg chaining for nowHerbert Xu1-0/+11
Unfortunately the generic chaining hasn't been ported to all architectures yet, and notably not s390. So this patch restores the chainging that we've been using previously which does work everywhere. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-01-11[CRYPTO] scatterwalk: Move scatterwalk.h to linux/cryptoHerbert Xu1-0/+107
The scatterwalk infrastructure is used by algorithms so it needs to move out of crypto for future users that may live in drivers/crypto or asm/*/crypto. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
