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 ] * tag 'asm-generic-alpha' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: alpha: drop pre-EV56 support alpha: cabriolet: remove EV5 CPU support alpha: remove LCA and APECS based machines alpha: sable: remove early machine support alpha: remove DECpc AXP150 (Jensen) support alpha: trim the unused stuff from asm-offsets.c alpha: jensen, t2 - make __EXTERN_INLINE same as for the rest alpha: core_lca: take the unused functions out alpha: missing includes alpha: sys_sio: fix misspelled ifdefs alpha: don't make functions public without a reason alpha: add clone3() support alpha: fix modversions for strcpy() et.al. alpha: sort scr_mem{cpy,move}w() out
