From: Nam Cao <namcaov@gmail.com> stable inclusion from stable-v6.6.3 commit a08b414d1ecec1ddc22b2d87f5c189aab1b3097b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- 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.
