36 | /* |
| 37 | * The COMPAT_SYSCALL_WRAP macro generates system call wrappers to be used by | |
| 38 | * compat tasks. These wrappers will only be used for system calls where only | |
| 39 | * the system call arguments need sign or zero extension or zeroing of the upper | |
| 40 | * 33 bits of pointers. | |
| 41 | * Note: since the wrapper function will afterwards call a system call which | |
| 42 | * again performs zero and sign extension for all system call arguments with | |
| 43 | * a size of less than eight bytes, these compat wrappers only touch those | |
| 44 | * system call arguments with a size of eight bytes ((unsigned) long and | |
| 45 | * pointers). Zero and sign extension for e.g. int parameters will be done by | |
| 46 | * the regular system call wrappers. | |
