From: Tiwei Bie Date: Sun, 8 Mar 2026 06:04:06 +0000 (+0800) Subject: um: Remove CONFIG_FRAME_WARN from x86_64_defconfig X-Git-Tag: v7.1-rc1~67^2~4 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=92d5c5c04eaa61f01c5b99bea9d639f0bd008036;p=thirdparty%2Flinux.git um: Remove CONFIG_FRAME_WARN from x86_64_defconfig The CONFIG_FRAME_WARN=1024 setting in x86_64_defconfig originates from arch/um/defconfig, which was split into i386_defconfig and x86_64_defconfig by commit e40f04d040c6 ("arch/um: make it work with defconfig and x86_64"). Currently, it's even smaller than the default on 32bit (i.e., 1280). It's no longer suitable for 64bit. Building with x86_64_defconfig triggers the following warning: lib/maple_tree.c: In function ‘mas_wr_bnode’: lib/maple_tree.c:3740:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=] 3740 | } | ^ Since we have a larger CONFIG_KERNEL_STACK_ORDER on 64bit (twice that of 32bit) by default, we could increase CONFIG_FRAME_WARN accordingly. Let's remove the CONFIG_FRAME_WARN=1024 setting from x86_64_defconfig and just use the default value (2048 for 64bit) defined in lib/Kconfig.debug, as we do for 32bit.
