I've been running the patches on the 6.12.11 kernel for over 24 hours
now.  Going very well and, in particular, I would like to note that:

The thread-test in the pixman package which has been failing for over
year 10 years on real Alpha hardware now passes!

I have now successfully built guile-3.0 with threading support!
Previously guile would lock up on Alpha if threading support was
enabled.

So there are some very long-standing bugs seen in user space that are
fixed by this patch series.

Cheers,
Michael.
