They are found when I try to rebase my swiotlb optimizations onto the
latest dma-mapping tree.

Patch 1 is to remove unused fields.
Patch 2-3 are to fix a corner case that area size can be smaller than the
number of slots in a segment (128). Such small areas conflict with an
implication of the mechanism used to track free slots.

Chao Gao (3):
  swiotlb: remove unused fields in io_tlb_mem
  swiotlb: consolidate rounding up default_nslabs
  swiotlb: ensure a segment doesn't cross the area boundary
