      [PATCH] x86_64: Log machine checks from boot on Intel systems · e583538f
      Andi Kleen authored
      
      
      The logging for boot errors was turned off because it was broken
      on some AMD systems. But give Intel EM64T systems a chance because they are
      supposed to be correct there.
      
      The advantage is that there is a chance to actually log uncorrected
      machine checks after the reset.

      [PATCH] x86_64: New heuristics to find out hotpluggable CPUs. · 420f8f68
      Andi Kleen authored
      
      
      With a NR_CPUS==128 kernel with CPU hotplug enabled we would waste 4MB
      on per CPU data of all possible CPUs.  The reason was that HOTPLUG
      always set up possible map to NR_CPUS cpus and then we need to allocate
      that much (each per CPU data is roughly ~32k now)
      
      The underlying problem is that ACPI didn't tell us how many hotplug CPUs
      the platform supports.  So the old code just assumed all, which would
      lead to this memory wastage.
      
      This implements some new heuristics:
      
       - If the BIOS specified disabled CPUs in the ACPI/mptables assume they
         can be enabled later (this is bending the ACPI specification a bit,
         but seems like a obvious extension)
       - The user can overwrite it with a new additionals_cpus=NUM option
       - Otherwise use half of the available CPUs or 2, whatever is more.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
