From 87615e95f6f9ccd36d4a3905a2d87f91967ea9d2 Mon Sep 17 00:00:00 2001 From: Nam Cao namcaov@gmail.com Date: Mon, 21 Aug 2023 16:57:09 +0200 Subject: [PATCH] riscv: put interrupt entries into .irqentry.text
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.
