6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nam Cao <namcaov@xxxxxxxxx>
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.
Fixes: 7db91e57a0ac ("RISC-V: Task implementation")
