Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
- racy use of ctx->rcvused in af_alg
- algif_aead crash in chacha20poly1305
- freeing bogus pointer in pcrypt
- build error on MIPS in mpi
- memory leak in inside-secure
- memory overwrite in inside-secure
- NULL pointer dereference in inside-secure
- state corruption in inside-secure
- build error without CRYPTO_GF128MUL in chelsio
- use after free in n2"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: inside-secure - do not use areq->result for partial results
crypto: inside-secure - fix request allocations in invalidation path
crypto: inside-secure - free requests even if their handling failed
crypto: inside-secure - per request invalidation
lib/mpi: Fix umul_ppmm() for MIPS64r6
crypto: pcrypt - fix freeing pcrypt instances
crypto: n2 - cure use after free
crypto: af_alg - Fix race around ctx->rcvused by making it atomic_t
crypto: chacha20poly1305 - validate the digest size
crypto: chelsio - select CRYPTO_GF128MUL
