Commitbe7635e728("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections") added a new linker section, SOFTIRQENTRY_TEXT, to the linker scripts for most architectures. It didn't add it to any of the linker scripts for the m68k architecture. This was not really a problem because it is only defined if either of CONFIG_FUNCTION_GRAPH_TRACER or CONFIG_KASAN are enabled - which can never be true for m68k. However commit229a718605("irq: Make the irqentry text section unconditional") means that SOFTIRQENTRY_TEXT is now always defined. So on m68k we now end up with a separate ELF section for .softirqentry.text instead of it being part of the .text section. On some m68k targets in some configurations this can also cause a fatal link error: LD vmlinux /usr/local/bin/../m68k-uclinux/bin/ld.real: section .softirqentry.text loaded at [0000000010de10c0,0000000010de12dd] overlaps section .rodata loaded at [0000000010de10c0,0000000010e0fd67] To fix add in the missing SOFTIRQENTRY_TEXT section into the m68k linker scripts. I noticed that m68k is also missing the IRQENTRY_TEXT section, so this patch also adds an entry for that too. Signed-off-by: Greg Ungerer <gerg@linux-m68k.org>
