From e31a374a99f5026df6ebff2a1c49492276e776fd Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Wed, 4 Mar 2026 19:15:48 +0100 Subject: [PATCH] fbdev: au1100fb: Fix build on MIPS64 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix an error reported by the kernel test robot: au1100fb.c: error: implicit declaration of function 'KSEG1ADDR'; did you mean 'CKSEG1ADDR'? arch/mips/include/asm/addrspace.h defines KSEG1ADDR only for 32 bit configurations. So provide its compile-test stub also for 64bit mips builds.
