| 32 | /* The files syswrap-generic.c, syswrap-linux.c, syswrap-x86-linux.c, |
| 33 | syswrap-amd64-linux.c and syswrap-ppc32-linux.c, and associated |
| 34 | vki*.h header files, constitute Valgrind's model of how a vanilla |
| 35 | Linux kernel behaves with respect to syscalls. |
| 36 | |
| 37 | On a few occasions, it is useful to run with a kernel that has some |
| 38 | (minor) extensions to the vanilla model, either due to running on a |
| 39 | hacked kernel, or using a vanilla kernel which has incorporated a |
| 40 | custom kernel module. Rather than clutter the standard model, all |
| 41 | such variant handlers are placed in here. |
| 42 | |
| 43 | Unlike the C files for the standard model, this file should also |
| 44 | contain all constants/types needed for said wrappers. The vki*.h |
| 45 | headers should not be polluted with non-vanilla info. */ |
