Please cite the exact commit from upstream where this comes from (I
imagine you could even use kernel.org proper, but I didn't check all
files just a few) and say for example:
Backport from linux commit 27406e978f596a646b87941cba5247eb0ccc8916

> +#ifndef	__ASM_GBL_DATA_H

Tabs instead of spaces.  I don't know why checkpatch didn't complain but
please give all of the files a quick check for things like <tab><space>
and '#define<tab>' and '#ifndef<tab>.

I spot-checked a few of the library files and they seem to match the
kernel which is important so I'll set aside disliking ';' as a comment
char.

You should be able to define a minimal set of prints here, see the
OpenRISC example above it.

Here and possibly another place or two in the file, just change the
check from defined(CONFIG_ARM) to defined(CONFIG_ARM) ||
defined(CONFIG_C6X).

Thanks!
