Retaining Alpha support means placing data dependency barriers (Linux kernel
term) where the Alpha memory model requires them. I doubt enough users will
stress Alpha builds for us to distinguish a missing barrier from hardware
flakiness, so we'd never find out whether we did it right. That's why I favor
removing Alpha-specific code completely, and it is an OS-independent and
compiler-independent motive.
