      [PATCH] Update PCI IOMEM allocation start · f0eca962
      Daniel Ritz authored
      
      
      This fixes the problem with "Averatec 6240 pcmcia_socket0: unable to
      apply power", which was due to the CardBus IOMEM register region being
      allocated at an address that was actually inside the RAM window that had
      been reserved for video frame-buffers in an UMA setup.
      
      The BIOS _should_ have marked that region reserved in the e820 memory
      descriptor tables, but did not.
      
      It is fixed by rounding up the default starting address of PCI memory
      allocations, so that we leave a bigger gap after the final known memory
      location.  The amount of rounding depends on how big the unused memory
      gap is that we can allocate IOMEM from.
      
      Based on example code by Linus.

      [PATCH] x86_64: Tell VM about holes in nodes · 485761bd
      Andi Kleen authored
      
      
      Some nodes can have large holes on x86-64.
      
      This fixes problems with the VM allowing too many dirty pages because it
      overestimates the number of available RAM in a node.  In extreme cases you
      can end up with all RAM filled with dirty pages which can lead to deadlocks
      and other nasty behaviour.
      
      This patch just tells the VM about the known holes from e820.  Reserved
      (like the kernel text or mem_map) is still not taken into account, but that
      should be only a few percent error now.
      
      Small detail is that the flat setup uses the NUMA free_area_init_node() now
      too because it offers more flexibility.
      
      (akpm: lotsa thanks to Martin for working this problem out)

      [PATCH] x86_64: Port over e820 gap detection from i386 · a1e97782
      Andi Kleen authored
      
      
      Look for gaps in the e820 memory map to put PCI resources in.
      
      This hopefully fixes problems with the PCI code assigning 32bit BARs MMIO
      resources which are >32bit.

      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!
