powerpc/64s: Tool to flag direct branches from unrelocated interrupt vectors
Direct banches from code below __end_interrupts to code above
__end_interrupts when built with CONFIG_RELOCATABLE are disallowed
because they will break when the kernel is not located at 0.
Sample output:
WARNING: Unrelocated relative branches
