Commit 2e8e1ea88cbc ("arm64: Use v8.5-RNG entropy for KASLR seed") introduced unconditional use of arm64-specific functions exported by asm/archrandom.h. With CONFIG_ARCH_RANDOM=y, this header is transitively included through linux/random.h. However, with CONFIG_ARCH_RANDOM=n, this header is not included, and the kernel fails to build.
Explicitly include asm/archrandom.h so __early_cpu_has_rndr() and __arm64_rndr() are always available, even when they are just stubs.
