I had investigated dropping support for alpha EV5 and earlier a while
ago after noticing that this is the only supported CPU family
in the kernel without native byte access and that Debian has already
dropped support for this generation last year [1] after it turned
out to be broken.

This topic came up again when Paul E. McKenney noticed that
parts of the RCU code already rely on byte access and do not
work on alpha EV5 reliably, so I refreshed my series now for
inclusion into the next merge window.

Al Viro did another series for alpha to address all the known build
issues. I rebased his patches without any further changes and included
it as a baseline for my work here to avoid conflicts.
