| 90 | * the old pre-4.x "mmap()", which: |
| 91 | * |
| 92 | * only let you map devices with an "mmap" routine (e.g., |
| 93 | * frame buffers) in; |
| 94 | * |
| 95 | * required you to specify the mapping address; |
| 96 | * |
| 97 | * returned 0 on success and -1 on failure; |
| 98 | * |
| 99 | * memory and which, and the 4.x "mmap()" which: |
| 100 | * |
| 101 | * can map plain files; |
| 102 | * |
| 103 | * can be asked to pick where to map the file; |
| 104 | * |
| 105 | * returns the address where it mapped the file on success |
| 106 | * and -1 on failure. |
| 107 | * |
| 108 | * It's not actually used in source code that calls "mmap()"; the |
| 109 | * "mmap()" routine adds it for you. |
| 110 | * |
| 111 | * It'd be nice to come up with some way of eliminating it from |
| 112 | * the flags, e.g. reporting calls *without* it as "old_mmap()" |
| 113 | * and calls with it as "mmap()". |
