/*
* NOTE-cpg-040217:
- *
+ *
* - when compiled as a module, after loading the module,
* it will refuse to unload, indicating it is in use,
* when it is not.
* 8: Present
* 7:6: reserved, write as zero
* 5:0: GATT directory index: which 1st-level entry
- *
+ *
* The Efficeon AGP spec requires pages to be WB-cacheable
* but to be explicitly CLFLUSH'd after any changes.
