[-dj patch] fix compilation with CONFIG_IKCONFIG

[Adrian Bunk]

Hi Dave,

compilation of CONFIG_IKCONFIG is broken in 2.5.39-dj2:

<--  snip  -->

...
  gcc -Wp,-MD,./.suspend.o.d -D__KERNEL__
-I/home/bunk/linux/kernel-2.5/linux-2.5.39-full/include -Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common
-pipe -mpreferred-stack-boundary=2 -march=k6
-I/home/bunk/linux/kernel-2.5/linux-2.5.39-full/arch/i386/mach-generic
-nostdinc -iwithprefix include    -DKBUILD_BASENAME=suspend   -c -o
suspend.o suspend.c
suspend.c:293: warning: #warning This might be broken. We need to somehow
wait for data to reach the disk
suspend.c: In function `bdev_write_page':
suspend.c:1040: warning: control reaches end of non-void function
make[1]: *** No rule to make target `configs.o', needed by `built-in.o'.
Stop.
make[1]: Leaving directory `/home/bunk/linux/kernel-2.5/linux-2.5.39-full/kernel'

<--  snip  -->


It seems the following part of 2.5.30-dj1 got lost (it applies with a few
lines offset):

You only think this is a free country. Like the US the UK spends a lot of
time explaining its a free country because its a police state.
