Hi Greg,

Today's linux-next build (x86_64 allmodconfig) produced this warning:

In file included from include2/asm/string.h:4,
                 from include/linux/string.h:19,
                 from include/linux/dynamic_printk.h:4,
                 from include/linux/kernel.h:19,
                 from arch/x86/boot/memory.c:16:
include2/asm/string_64.h:34:1: warning: "memcpy" redefined
In file included from /scratch/sfr/next/arch/x86/boot/memory.c:15:
arch/x86/boot/boot.h:231:1: warning: this is the location of the previous definition

Probably caused by commit 1b75321c2d0561d9ecfe3794fa939264f3eb7e26
("driver core: basic infrastructure for per-module dynamic debug
messages") which added an include of linux/dynamic_printk.h to
linux/kernel.h.

Wierd.  Jason, any thoughts?

thanks,

hmm...i wasn't actually able to reproduce this (gcc 4.3.0-8), but I think I see
how this comes about. Anyways, we don't actually need to include "string.h",
its a remnant from an earlier version. The following patch should resolve this
issue.

Thanks, I've merged this with the original one.
