From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>
#include <linux/printk.h> since that is where kptr_restrict is externed.
Put kptr_restrict inside #ifdef CONFIG_PRINTK block to fix build error
when CONFIG_PRINTK is not enabled:
kernel/sysctl.c:712: error: 'kptr_restrict' undeclared here (not in a function)
