The convention used in other kernel headers (e.g. wait.h, percpu-defs.h) is to use "DECLARE_" prefix for macros emitting externs, static inlines and type definitions. The "DEFINE_" prefix is used for variable definitions. In preparation to introduce a "DEFINE_INACTIVE_GUARD()" to actually define a guard variable, rename all the guard "DEFINE_" prefix to "DECLARE_".
