You can enable COMPAT_VDSO, recompile your kernel, and echo 0 >
/proc/sys/kernel/vdso; or you can add vdso=0 in the kernel boot
options. This will possibly make things slower... how much? I have no
idea, people have given me different answers.

There doesn't seem to be a lot of information regarding vdso, but this
is what I've found so far:

* vDSO = Virtual Dynamically Shared Object
* Without COMPAT_VDSO there's no /proc/sys/kernel/vdso
* linux-gate.so.1 is a vDSO
* Linus Torvalds is a disgusting pig and proud of it


Best regards.
