From bb305783b9632437dc5ce1f31ee35d226b26888b Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 12 Mar 2025 22:51:00 +0900 Subject: [PATCH] modpost: Add .irqentry.text to OTHER_SECTIONS BugLink: https://bugs.launchpad.net/bugs/2102118 commit 7912405643a14b527cd4a4f33c1d4392da900888 upstream. The compiler can fully inline the actual handler function of an interrupt entry into the .irqentry.text entry point. If such a function contains an access which has an exception table entry, modpost complains about a section mismatch: WARNING: vmlinux.o(__ex_table+0x447c): Section mismatch in reference ... The relocation at __ex_table+0x447c references section ".irqentry.text" which is not in the list of authorized sections. Add .irqentry.text to OTHER_SECTIONS to cure the issue.
