Subject: riscv: put interrupt entries into .irqentry.text
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=87615e95f6f9ccd36d4a3905a2d87f91967ea9d2;p=linux.git

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.
