| The files in ``/proc/sys/abi`` can be used to see and modify |
| ABI-related settings. |

| Currently, these files might (depending on your configuration) |
| show up in ``/proc/sys/kernel``: |

| vsyscall32 (x86) |
| ================ |
| |
| Determines whether the kernels maps a vDSO page into 32-bit processes; |
| can be set to 1 to enable, or 0 to disable. Defaults to enabled if |
| ``CONFIG_COMPAT_VDSO`` is set, disabled otherwide. |
| |
| This controls the same setting as the ``vdso32`` kernel boot |
| parameter. |
