[PATCH 0/4] refine mas_end of mas_mab_cp()

[Wei Yang]

mas_mab_cp() copy range [mas_start, mas_end] inclusively. For some usage, the
mas_end passed could be refined.

Patch 1: if we know the end of a maple_node, we don't need to copy end + 1.
Patch 2: this one tries to leverage mt_pivot_count() for optimize the code.
Patch 3: the maximum end of a maple_node is mt_pivot_count() instead of
         mt_slot_count()
Patch 4: after above cleanup, we are sure mas_end won't exceed mt_pivots[], so
         we can remove the check in mas_mab_cp()

Wei Yang (4):
  maple_tree: not necessary to copy mas->end + 1
  maple_tree: use mt_pivot_count() to replace mt_slot_count() - 1
  maple_tree: copy to mt_pivot_count() instead of mt_slot_count()
  maple_tree: now we are sure mas_end wouldn't exceed mt_pivots[mt]
