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"
