   [IA64] cyclone.c: Add includes for build on uni-processor.
   
   Small patch to fix the includes for the cyclone timer.  We just happen to be
   getting these if CONFIG_SMP is on, but if it's turned off the build breaks.

   [IA64-SGI] report coherence id in /proc/sgi_sn/coherence_id
   
   Current SGI Altix systems have a NUMAlink domain size of 1024
   compute nodes and are fully cache coherent up to 256 compute
   nodes (compute nodes are even-numbered).  Systems larger than
   256 nodes are partitioned into multiple cache coherent systems.
   This patch exports a partition's coherence id to users via the
   /proc/sgi_sn/coherence_id file.

   [IA64] time.c: Downgrade printk of cpu speed to KERN_DEBUG
   
   This patch turns the per-CPU frequency printk into a KERN_DEBUG instead of a
   KERN_INFO so it'll show up in the system log but won't be printed at boot,
   since it's a big pain on system with a lot of CPUs.

   [IA64-SGI] bte.c: kill expression as lvalue warning
   
   A recent patch caused a warning about not using expressions as lvalues
   to crop up in bte.c (or maybe it's just that I'm using gcc-3.4.1 now).
   This patch fixes it by creating a temporary to store the register whose
   address we want to get and stuff into the per-bte info structure.

   [IA64-SGI] Assign parent to PCI devices.
   
   In working on the patch to export PCI ROM space via sysfs, I found that the
   sn2 PCI code doesn't assign a parent resource to any of the PCI device
   resources as it builds them.  This provides a simple fix for that problem.

   [IA64] various issues in the IA64 swiotlb code
   
   The biggest change is better overflow handling, partly ported from the AMD64 
   IOMMU  code.  This is important for some 3d drivers who make use of this and can 
   map a lot of memory.
   
   First it increases the default memory usage of swiotlb to 64MB.
   This was the value used in production systems in 2.4 (e.g. in SLES8) and the default
   was far too small.  Note this is only allocated when the swiotlb is needed.
   
   pci_map_single will not panic anymore on an overflow. Instead it returns
   a pointer to a scratch area and allows the caller to check using 
   dma_mapping_error(). It still panics when the overflow buffer is exceeded.
   
   dma_mapping_error support is implemented.
   
   pci_map_sg will never panic now, but just return 0. Near all callers 
   of it seem to have proper error checking for this (IDE will even handle
   it without erroring out) 
   
   The handling of passing a NULL device is improved, previously it would 
   never map in this case. i386 and other architectures assume NULL means a 4GB
   limit instead.   This code does this now too.
   
   I added support for swiotlb=force for easier testing.
