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 otherwise.
This controls the same setting as the vdso32 kernel boot
parameter.
