[PATCH 1/3] Restrict definition of a variable in kernel/sysctl.c
From: Dmitri Vorobiev
Date: Wed Mar 18 2009 - 18:00:59 EST
The variable "one" in kernel/sysctl.c is used only if either CONFIG_HIGHMEM,
or CONFIG_DETECT_SOFTLOCKUP are defined (or both). Hence, if neither option
is enabled, the following error is produced:
CC kernel/sysctl.o
kernel/sysctl.c:99: warning: 'one' defined but not used
This patch fixes the warning by moving the variable definition under an
appropriate preprocessor construct.
