Hi Axel,

When I applied this in my tree, happened following error with s3c6400_defconfig.

arch/arm/plat-samsung/s3c-dma-ops.c:17: fatal error: linux/export.h: No such file or directory

Probably the <linux/export.h> file has been added from other tree.
So if required, will fix with this during upcoming merge window maybe at end of.

Thanks.

Best regards,
Kgene.
