[Xen-users] Link to kernelcap documentation?

[Tomas Kouba <tomas@xxxxxxxx>]

Hi,

Fedora has a nice solution for glibc performance problems. They have 
libraries compiled with nosegneg and they let dynamic linker to choose 
according to running kernel.
Does anybody know where a documentation for this feature is? (is it 
fedora specific or already included in vanilla kernel/linker?)
I would like to know more about this but couldn't google anything 
valuable. The problem is, that I don't know the exact name of th feature 
:) (i tried 'kernelcap vdso xen fedora' and some combinations).
Thanks
