From ff5900092227ade3e31fe25f97faf406cde902e6 Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Thu, 21 Jul 2022 12:04:33 +0200 Subject: [PATCH] arm64: adjust KASLR relocation after ARCH_RANDOM removal Commit aacd149b6238 ("arm64: head: avoid relocating the kernel twice for KASLR") adds the new file arch/arm64/kernel/pi/kaslr_early.c with a small code part guarded by '#ifdef CONFIG_ARCH_RANDOM'. Concurrently, commit 9592eef7c16e ("random: remove CONFIG_ARCH_RANDOM") removes the config CONFIG_ARCH_RANDOM and turns all '#ifdef CONFIG_ARCH_RANDOM' code parts into unconditional code parts, which is generally safe to do. Remove a needless ifdef guard after the ARCH_RANDOM removal.
