[PATCH v2] riscv: put interrupt entries into .irqentry.text

[PATCH v2] riscv: put interrupt entries into .irqentry.text

[Nam Cao]

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.
