> files
>
> When building block/blk-iocost.c on arch/x6x/ or arch/nios2/, the build fails
> due to missing the <asm/local64.h> file.
>
> Fix this by adding local64.h as a "generic-y" file in their respective Kbuild
> files,
> so that they will use a copy of <asm-generic/local64.h> instead (copied to
> arch/*/include/generated/local64.h by the build system).

> c6x or nios2 build error:
> ../block/blk-iocost.c:183:10: fatal error: asm/local64.h: No such file or
> directory
> 183 | #include <asm/local64.h>
>
> Fixes: 5e124f74325d ("blk-iocost: use local[64]_t for percpu stat")
