Merge tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator fixes from Jason Donenfeld: - If a hardware random number generator passes a sufficiently large chunk of entropy to random.c during early boot, we now skip the "fast_init" business and let it initialize the RNG. This makes CONFIG_RANDOM_TRUST_BOOTLOADER=y actually useful. - We already have the command line `random.trust_cpu=0/1` option for RDRAND, which let distros enable CONFIG_RANDOM_TRUST_CPU=y while placating concerns of more paranoid users. Now we add `random.trust_bootloader=0/1` so that distros can similarly enable CONFIG_RANDOM_TRUST_BOOTLOADER=y. - Re-add a comment that got removed by accident in the recent revert. - Add the spec-compliant ACPI CID for vmgenid, which Microsoft added to the vmgenid spec at Ard's request during earlier review. - Restore build-time randomness via the latent entropy plugin, which was lost when we transitioned to using a hash function. * tag 'random-5.18-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: mix build-time latent entropy into pool at init virt: vmgenid: recognize new CID added by Hyper-V random: re-add removed comment about get_random_{u32,u64} reseeding random: treat bootloader trust toggle the same way as cpu trust toggle random: skip fast_init if hwrng provides large chunk of entropy
