Subject: Fix kernel build with EMBEDDED & PROC_FS & !PROC_SYSCTL
From: "Mika Kukkonen" <mikukkon@xxxxxx>
Without attached patch against current -git I get following with
!PROC_SYSCTL (with EMBEDDED and PROC_FS set):
CC init/version.o
LD init/built-in.o
LD vmlinux

make: *** [vmlinux] Virhe 1
All those functions are in fs/proc/proc_sysctl.c, which has no CONFIG_
#define's in it, so the patch makes the compilation of that file to depend
on CONFIG_PROC_SYSCTL (the simplest choice).
