+/* These macros are used to mark some functions or
+ * initialized data (doesn't apply to uninitialized data)
+ * as `initialization' functions. The kernel can take this
+ * as hint that the function is used only during the initialization
+ * phase and free up used memory resources after
+ *
+ * Usage:
+ * For functions:
+ *
+ * You should add __init immediately before the function name, like:
+ *
+ * static void __init initme(int x, int y)
+ * {
+ * extern int z; z = x * y;
+ * }
+ *
+ * Depricated: you can surround the whole function declaration
+ * just before function body into __initfunc() macro, like:
+ *
+ * __initfunc (static void initme(int x, int y))
+ * {
+ * extern int z; z = x * y;
+ * }
+ *
+ * If the function has a prototype somewhere, you can also add
+ * __init between closing brace of the prototype and semicolon:
+ *
+ * extern int initialize_foobar_device(int, int, int) __init;
+ *
+ * For initialized data:
+ * You should insert __initdata between the variable name and equal
+ * sign followed by value, e.g.:
+ *
+ * static int init_variable __initdata = 0;
+ * static char linux_logo[] __initdata = { 0x32, 0x36, ... };
+ *
+ * For initialized data not at file scope, i.e. within a function,
+ * you should use __initlocaldata instead, due to a bug in GCC 2.7.
+ */
+
+/*
+ * Disable the __initfunc macros if a file that is a part of a
+ * module attempts to use them. We do not want to interfere
+ * with module linking.
