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
