- * IO, register, and NIC memory access functions
- *
- * NOTE on naming convention and macro usage for these
- *
- * A single _ prefix before a an access function means that no state
- * check or debug information is printed when that function is called.
- *
- * A double __ prefix before an access function means that state is checked
- * (in the case of *restricted calls) and the current line number is printed
- * in addition to any other debug output.
- *
- * The non-prefixed name is the #define that maps the caller into a
- * #define that provides the caller's __LINE__ to the double prefix version.
- *
- * If you wish to call the function without any debug or state checking,
- * you should use the single _ prefix version (as is used by dependent IO
- * routines, for example _iwl_read_restricted calls the non-check version of
- * _iwl_read32.)
- *
- * These declarations are *extremely* useful in quickly isolating code deltas
- * which result in misconfiguring of the hardware I/O. In combination with
- * git-bisect and the IO debug level you can quickly determine the specific
- * commit which breaks the IO sequence to the hardware.
