Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Add the ability to abort a skcipher walk. Algorithms: - Fix XTS to actually do the stealing. - Add library helpers for AES and DES for single-block users. - Add library helpers for SHA256. - Add new DES key verification helper. - Add surrounding bits for ESSIV generator. - Add accelerations for aegis128. - Add test vectors for lzo-rle. Drivers: - Add i.MX8MQ support to caam. - Add gcm/ccm/cfb/ofb aes support in inside-secure. - Add ofb/cfb aes support in media-tek. - Add HiSilicon ZIP accelerator support. Others: - Fix potential race condition in padata. - Use unbound workqueues in padata" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (311 commits) crypto: caam - Cast to long first before pointer conversion crypto: ccree - enable CTS support in AES-XTS crypto: inside-secure - Probe transform record cache RAM sizes crypto: inside-secure - Base RD fetchcount on actual RD FIFO size crypto: inside-secure - Base CD fetchcount on actual CD FIFO size crypto: inside-secure - Enable extended algorithms on newer HW crypto: inside-secure: Corrected configuration of EIP96_TOKEN_CTRL crypto: inside-secure - Add EIP97/EIP197 and endianness detection padata: remove cpu_index from the parallel_queue padata: unbind parallel jobs from specific CPUs padata: use separate workqueues for parallel and serial work padata, pcrypt: take CPU hotplug lock internally in padata_alloc_possible crypto: pcrypt - remove padata cpumask notifier padata: make padata_do_parallel find alternate callback CPU workqueue: require CPU hotplug read exclusion for apply_workqueue_attrs workqueue: unconfine alloc/apply/free_workqueue_attrs() padata: allocate workqueue internally arm64: dts: imx8mq: Add CAAM node random: Use wait_event_freezable() in add_hwgenerator_randomness() crypto: ux500 - Fix COMPILE_TEST warnings ...
