From 7912405643a14b527cd4a4f33c1d4392da900888 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner tglx@linutronix.de Date: Sun, 1 Dec 2024 12:17:30 +0100 Subject: [PATCH] modpost: Add .irqentry.text to OTHER_SECTIONS

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.
