From 05b2911ac941ab9cc66305824a4d8bacea7f01c8 Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Mon, 21 Aug 2023 16:57:09 +0200 Subject: [PATCH] riscv: put interrupt entries into .irqentry.text commit 87615e95f6f9ccd36d4a3905a2d87f91967ea9d2 upstream. The interrupt entries are expected to be in the .irqentry.text section. For example, for kprobes to work properly, exception code cannot be probed; this is ensured by blacklisting addresses in the .irqentry.text section.
