Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Removed CRYPTO_TFM_RES flags - Extended spawn grabbing to all algorithm types - Moved hash descsize verification into API code Algorithms: - Fixed recursive pcrypt dead-lock - Added new 32 and 64-bit generic versions of poly1305 - Added cryptogams implementation of x86/poly1305 Drivers: - Added support for i.MX8M Mini in caam - Added support for i.MX8M Nano in caam - Added support for i.MX8M Plus in caam - Added support for A33 variant of SS in sun4i-ss - Added TEE support for Raven Ridge in ccp - Added in-kernel API to submit TEE commands in ccp - Added AMD-TEE driver - Added support for BCM2711 in iproc-rng200 - Added support for AES256-GCM based ciphers for chtls - Added aead support on SEC2 in hisilicon" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (244 commits) crypto: arm/chacha - fix build failured when kernel mode NEON is disabled crypto: caam - add support for i.MX8M Plus crypto: x86/poly1305 - emit does base conversion itself crypto: hisilicon - fix spelling mistake "disgest" -> "digest" crypto: chacha20poly1305 - add back missing test vectors and test chunking crypto: x86/poly1305 - fix .gitignore typo tee: fix memory allocation failure checks on drv_data and amdtee crypto: ccree - erase unneeded inline funcs crypto: ccree - make cc_pm_put_suspend() void crypto: ccree - split overloaded usage of irq field crypto: ccree - fix PM race condition crypto: ccree - fix FDE descriptor sequence crypto: ccree - cc_do_send_request() is void func crypto: ccree - fix pm wrongful error reporting crypto: ccree - turn errors to debug msgs crypto: ccree - fix AEAD decrypt auth fail crypto: ccree - fix typo in comment crypto: ccree - fix typos in error msgs crypto: atmel-{aes,sha,tdes} - Retire crypto_platform_data crypto: x86/sha - Eliminate casts on asm implementations ...
