Merge tag 'v6.1-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu: "API: - Feed untrusted RNGs into /dev/random - Allow HWRNG sleeping to be more interruptible - Create lib/utils module - Setting private keys no longer required for akcipher - Remove tcrypt mode=1000 - Reorganised Kconfig entries Algorithms: - Load x86/sha512 based on CPU features - Add AES-NI/AVX/x86_64/GFNI assembler implementation of aria cipher Drivers: - Add HACE crypto driver aspeed" * tag 'v6.1-p1' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (124 commits) crypto: aspeed - Remove redundant dev_err call crypto: scatterwalk - Remove unused inline function scatterwalk_aligned() crypto: aead - Remove unused inline functions from aead crypto: bcm - Simplify obtain the name for cipher crypto: marvell/octeontx - use sysfs_emit() to instead of scnprintf() hwrng: core - start hwrng kthread also for untrusted sources crypto: zip - remove the unneeded result variable crypto: qat - add limit to linked list parsing crypto: octeontx2 - Remove the unneeded result variable crypto: ccp - Remove the unneeded result variable crypto: aspeed - Fix check for platform_get_irq() errors crypto: virtio - fix memory-leak crypto: cavium - prevent integer overflow loading firmware crypto: marvell/octeontx - prevent integer overflows crypto: aspeed - fix build error when only CRYPTO_DEV_ASPEED is enabled crypto: hisilicon/qm - fix the qos value initialization crypto: sun4i-ss - use DEFINE_SHOW_ATTRIBUTE to simplify sun4i_ss_debugfs crypto: tcrypt - add async speed test for aria cipher crypto: aria-avx - add AES-NI/AVX/x86_64/GFNI assembler implementation of aria cipher crypto: aria - prepare generic module for optimized implementations ...
