Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

- * module_param - typesafe helper for a module/cmdline parameter
- * @value: the variable to alter, and exposed parameter name.
- * @type: the type of the parameter
- * @perm: visibility in sysfs.
- *
- * @value becomes the module parameter, or (prefixed by KBUILD_MODNAME and a
- * ".") the kernel commandline parameter. Note that - is changed to _, so
- * the user can use "foo-bar=1" even for variable "foo_bar".
- *
- * @perm is 0 if the the variable is not to appear in sysfs, or 0444
- * for world-readable, 0644 for root-writable, etc. Note that if it
- * is writable, you may need to use kparam_block_sysfs_write() around
- * accesses (esp. charp, which can be kfreed when it changes).
- *
- * The @type is simply pasted to refer to a param_ops_##type and a
- * param_check_##type: for convenience many standard types are provided but
- * you can create your own by defining those variables.
- *
- * Standard types are:
- * byte, short, ushort, int, uint, long, ulong
- * charp: a character pointer
- * bool: a bool, values 0/1, y/n, Y/N.
- * invbool: the above, only sense-reversed (N = true).
