[PATCH] x86_64: Clean and enhance up K8 northbridge access code
- 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.
