Hi Russell, Thanks for having a look. Russell King - ARM Linux [off-list ref] writes:

While it means that this file gets built on both arm64 and arm, it means that it routinely won't get tested on arm64 when changes to it happen.
I agree. An earlier version of this patch copied opcodes.c to arm64 but then it wouldn't benefit from any fixes that would go in the original. The current approach misses out on the testing. Although better than the previous approach, it is not optimal.
The second reason it's not nice is that the whole $(addprefix thing really isn't needed. You're only adding the prefix to one name. So, a simpler way to write it is "../../arm/kernel/opcodes.o".
This one is easy to make nice. Fixed in my local copy. Cheers, Punit
