      x86: cleanup PAT cpu validation · 8d4a4300
      Thomas Gleixner 提交于
      Move the scattered checks for PAT support to a single function. Its
      moved to addon_cpuid_features.c as this file is shared between 32 and
      64 bit.
      
      Remove the manipulation of the PAT feature bit and just disable PAT in
      the PAT layer, based on the PAT bit provided by the CPU and the
      current CPU version/model white list.
      
      Change the boot CPU check so it works on Voyager somewhere in the
      future as well :) Also panic, when a secondary has PAT disabled but
      the primary one has alrady switched to PAT. We have no way to undo
      that.
      
      The white list is kept for now to ensure that we can rely on known to
      work CPU types and concentrate on the software induced problems
      instead of fighthing CPU erratas and subtle wreckage caused by not yet
      verified CPUs. Once the PAT code has stabilized enough, we can remove
      the white list and open the can of worms.

      x86: remove NexGen support · f7f17a67
      Dmitri Vorobiev 提交于
      It is claimed that NexGen CPUs were never shipped:
      
         http://lkml.org/lkml/2008/4/20/179
      
      Also, the kernel support for these chips has been broken for
      a long time, the code intended to support NexGen thereby being
      essentially dead.
      
      As an outcome of the discussion that can be found using the URL
      above, this patch removes the NexGen support altogether.
      
      The changes in this patch survived a defconfig build for i386, a
      couple of successful randconfig builds, as well as a runtime test,
      which consisted in booting a 32-bit x86 box up to the shell prompt.

      x86: remove unused function amd_init_cpu() · f3b14a32
      Dmitri Vorobiev 提交于
      There are no users for the function amd_init_cpu() defined in
      arch/x86/kernel/cpu/amd.c. This patch removes this routine.
      
      This patch was build-tested using defconfigs for i386 and x86_64,
      and a few randconfig instances. Runtime tests were performed by
      booting 32- and 64-bit x86 boxen up to the shell prompt.

      x86-64: extend MCE CPU quirk handling · 911f6a7b
      Jan Beulich 提交于
      At least on my Barcelona, I see MCE log entries after cold boot caused
      by BIOS not properly clearing the respective registers. Therefore, this
      patch extends the workaround to families 0x10 and 0x11 (the latter just
      for completeness, I have nothing to verify this against).
      At the same time, provide a way to make these entries visible via the
      'mce=bootlog' command line option even on these machines.

      x86: fix watchdog ops for CoreDuo · 86d78f64
      Jan Beulich 提交于
      There apparently was an unnoticed conflict between an earlier patch to
      this file and mine (d1e08474), which
      I noticed only now. I suppose a change like the one below (untested) is
      needed; I didn't get any response on a confirmation request for this from
      the submitter of the first patch.
      
      The issue is the writing of the 'checkbit' member at the end of
      setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops
      rather than wd_ops.
