The glibc vdso code for s390 uses the version string 2.6.29, the kernel uses the version string 2.6.26. No wonder the vdso code is never used. The first kernel version to contain the vdso code is 2.6.29 which makes this the correct version. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
