Subject: [PATCH] arm64: Fix CONFIG_ARCH_RANDOM=n build
Date: Mon, 10 Feb 2020 19:21:01 +0000	[thread overview]
Message-ID: <245aede65d9834101efc9e470f50633b7052e1a8.1581362270.git.robin.murphy@arm.com> (raw)

The entire asm/archrandom.h header is generically included via
linux/archrandom.h only when CONFIG_ARCH_RANDOM is already set, so the
stub definitions of __arm64_rndr() and __early_cpu_has_rndr() are only
visible to KASLR if it explicitly includes the arch-internal header.
