From e13d32e99264e0b63b01417e2f2db627f4507b97 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 16 May 2023 18:06:41 +0200 Subject: [PATCH] arm64: move early_brk64 prototype to header The prototype used for calling early_brk64() is in the file that calls it, which is the wrong place, as it is not included for the definition: arch/arm64/kernel/traps.c:1100:12: error: no previous prototype for 'early_brk64' [-Werror=missing-prototypes] Move it to an appropriate header instead.
