Subject: [PATCH 0/2] dma-mapping: update default segment_boundary_mask

These two patches are to update default segment_boundary_mask.

PATCH-1 fixes overflow issues in callers of dma_get_seg_boundary.
Previous version was a series: https://lkml.org/lkml/2020/8/31/1026

Then PATCH-2 sets default segment_boundary_mask to ULONG_MAX.

Nicolin Chen (2):
  dma-mapping: introduce dma_get_seg_boundary_nr_pages()
  dma-mapping: set default segment_boundary_mask to ULONG_MAX
