  [PATCH] x86_64: Try harder to allocate memory in pci_alloc_consistent()
  
  Try harder to allocate memory in pci_alloc_consistent()
  
  First try to allocate without GFP_DMA and see if we were lucky
  and the memory fits into the requested physical range. Only
  if that fails fall back to swiotlb. This makes pci_alloc_consistent
  more reliable, especially on systems without hardware IOMMU
  (Intel systems)
  
  Increase the default swiotlb window size to 64MB.
