The changelog of the commit below explains that.
commit 1dbf527c51c6c20c19869c8125cb5b87c3d09506 Author: Jeremy Fitzhardinge <jeremy@goop.org> Date: Wed May 2 19:27:12 2007 +0200
[PATCH] i386: Make COMPAT_VDSO runtime selectable.
Now that relocation of the VDSO for COMPAT_VDSO users is done at runtime rather than compile time, it is possible to enable/disable compat mode at runtime.
This patch allows you to enable COMPAT_VDSO mode with "vdso=2" on the kernel command line, or via sysctl. (Switching on a running system shouldn't be done lightly; any process which was relying on the compat VDSO will be upset if it goes away.)
The COMPAT_VDSO config option still exists, but if enabled it just makes vdso_enabled default to VDSO_COMPAT.
