Merge tag 'asm-generic-alpha' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull alpha updates from Arnd Bergmann:
 "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] in order to improve
  performance for the newer machines.

  This topic came up again when Paul McKenney noticed that parts of the
  RCU code already rely on byte access and do not work on alpha EV5
  reliably, so we decided on using my series to avoid the problem
  entirely.

  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 and allow
  backporting the fixes to stable kernels for the now removed hardware
  support as well"

[ I dearly loved alpha back in the days, but the lack of byte and word
  operations was a horrible mistake and made everything worse -
  including very much the crazy IO contortions that resulted from it.

  It certainly wasn't the only mistake in the architecture, but it's the
  first-order issue.

  So while it's a bit sad to see the support for my first alpha go away,
  if you want to run museum hardware, maybe you should use museum
  kernels..    - Linus ]
