    [PATCH] x86_64: Clean and enhance up K8 northbridge access code · a32073bf
    Andi Kleen 提交于
     - Factor out the duplicated access/cache code into a single file
       * Shared between i386/x86-64.
     - Share flush code between AGP and IOMMU
       * Fix a bug: AGP didn't wait for end of flush before
     - Drop 8 northbridges limit and allocate dynamically
     - Add lock to serialize AGP and IOMMU GART flushes
     - Add PCI ID for next AMD northbridge
     - Random related cleanups
    
    The old K8 NUMA discovery code is unchanged. New systems
    should all use SRAT for this.
