In the provided config, it has: # CONFIG_MMU is not set and all kexec/kdump related config items are unset. The if (!IS_ENABLED(CONFIG_CRASH_RESERVE)) checking will cause funciton reserve_crashkernel() is compiled, but not built in. With CONFIG_MMU=no, SECTION_SIZE is undefined on arm. So fix it by wrapping up reserve_crashkernel() inside CONFIG_CRASH_RESERVE ifdeffery scope. >From d580b65f6aa042233e228aab45609c3de88ab29e Mon Sep 17 00:00:00 2001 From: Baoquan He <bhe@xxxxxxxxxx> Date: Mon, 15 Jan 2024 22:32:19 -0500 Subject: [PATCH] arm, crash: wrap crash dumping code into crash related ifdefs Content-type: text/plain Now crash codes under kernel/ folder has been split out from kexec code, crash dumping can be separated from kexec reboot in config items on arm with some adjustments. Here use CONFIG_CRASH_RESERVE ifdef to replace CONFIG_KEXEC ifdef.
