Oh, I missed that and will fix it.  But where does the missing removal
actually show up?  During a normal build on a few architectures nothing
seemed to care.

There are indeed no errors or warnings from Kbuild if you remove a
file from include/asm-generic. Only if you try to #include it, it will fail.

Ah, it just creates a file that includes the generic version, whether it
exists or not:

$ cat arch/arm/include/generated/asm/scatterlist.h
#include <asm-generic/scatterlist.h>
$
