This is a rebuild to remove nopl instructions on i686 so those "i686" processors (e.g. Via C3 Nehemiah) that do not support it do not crash a lot. This issue was supposed to be fixed upstream in binutils-2.21 so the old work around for this was removed from our glibc package. Turns out, the binutils fix was not as much of a fix as was previously thought...
binutils-2.21-4: - new snapshot from 2.21 branch - add upstream patch to stop nopl usage on i686
glibc-2.13-3: - rebuild to remove nopl instructions
Before:
objdump -d /lib/ld-2.13.so | grep nopl | wc -l

After
objdump -d /lib/ld-2.13.so | grep nopl | wc -l

glibc is probably the only package that needed rebuilt to remove those instructions as its build forces --mtune=i686 when --march=i686 is used. Those package that listen to --mtune=generic are fine.
As an FYI for people who were affected by this. I have had reports that a Via C3 Nehemiah now works and that an AMD Geode required a kernel rebuild with these to no have a kernel panic on boot but then seemed fine.
Allan Hi i rebuilt the kernel-26 and kernel26-lts packages with latest gcc and binutils, shall i push them to testing?
Sure. Allan
