Merge tag 'v6.18-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "Drivers: - Add ciphertext hiding support to ccp - Add hashjoin, gather and UDMA data move features to hisilicon - Add lz4 and lz77_only to hisilicon - Add xilinx hwrng driver - Add ti driver with ecb/cbc aes support - Add ring buffer idle and command queue telemetry for GEN6 in qat Others: - Use rcu_dereference_all to stop false alarms in rhashtable - Fix CPU number wraparound in padata" * tag 'v6.18-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (78 commits) dt-bindings: rng: hisi-rng: convert to DT schema crypto: doc - Add explicit title heading to API docs hwrng: ks-sa - fix division by zero in ks_sa_rng_init KEYS: X.509: Fix Basic Constraints CA flag parsing crypto: anubis - simplify return statement in anubis_mod_init crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs crypto: hisilicon/qm - clear all VF configurations in the hardware crypto: hisilicon - enable error reporting again crypto: hisilicon/qm - mask axi error before memory init crypto: hisilicon/qm - invalidate queues in use crypto: qat - Return pointer directly in adf_ctl_alloc_resources crypto: aspeed - Fix dma_unmap_sg() direction rhashtable: Use rcu_dereference_all and rcu_dereference_all_check crypto: comp - Use same definition of context alloc and free ops crypto: omap - convert from tasklet to BH workqueue crypto: qat - Replace kzalloc() + copy_from_user() with memdup_user() crypto: caam - double the entropy delay interval for retry padata: WQ_PERCPU added to alloc_workqueue users padata: replace use of system_unbound_wq with system_dfl_wq crypto: cryptd - WQ_PERCPU added to alloc_workqueue users ...
