Glibc trunk, 2.12, 2.11 has
if (__cpu_features.family == 0x0f)
{
family += extended_family;
model += extended_model;
}
else if (__cpu_features.family == 0x06)
{
model += extended_model;
switch (__cpu_features.model)
...
__cpu_features.family = family;
__cpu_features.model = model;
__cpu_features.family and __cpu_features.family are checked
before they are set. A patch is posted at
http://sourceware.org/ml/libc-alpha/2010-05/msg00048.html
It should be applied cleanly to trunk and 2.12. 2.11 needs
small changes.

In principle, there should be no need to reopen the bug for that, keywords
should be enough. Unfortunately, there is no glibc_2.12 keyword, Andreas, can
you look into that please?

Don't reopen bugs for this. The branch maintainers will in any case have to
look at each bug and backport them in turn.
