Please move sed-y and filechk_offsets to scripts/Makefile.lib .
(You may need to rename sed-y
because arch/xtensa/kernel/Makefile uses this name.)


We see various helpers in scripts/Makefile.lib,
so I do not think we need to create a new file just for this one.

Then, please reuse it from arch/ia64/kernel/Makefile and scripts/mod/Makefile.
Like this:

include/generated/nr-irqs.h: arch/$(SRCARCH)/kernel/nr-irqs.s FORCE
        $(call filechk,offsets,__ASM_NR_IRQS_H__)

$(obj)/$(devicetable-offsets-file): $(obj)/devicetable-offsets.s FORCE
        $(call filechk,offsets,__DEVICETABLE_OFFSETS_H__)
