[PATCH] [23/48] i386: VDSO_PRELINK warning fix

From: Andi Kleen
Date: Sun Apr 29 2007 - 07:11:46 EST



From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>

The lguest patches somehow managed to trigger this:

In file included from arch/i386/lguest/lguest.c:38:
include/asm/asm-offsets.h:67:1: warning: "VDSO_PRELINK" redefined
In file included from include/linux/elf.h:7,
from include/linux/module.h:15,
from include/linux/device.h:21,
from include/linux/interrupt.h:15,
from arch/i386/lguest/lguest.c:27:
include/asm/elf.h:140:1: warning: this is the location of the previous definition

I assume that using the same identifier twice was a bad idea..
