[Andrew Morton]

The quilt patch titled
     Subject: maple_tree: make ma_wr_states reliable for reuse in spanning store
has been removed from the -mm tree.  Its filename was
     maple_tree-make-ma_wr_states-reliable-for-reuse-in-spanning-store.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

mas_extend_spanning_null() was not modifying the range min and range max
of the resulting store operation.  The result was that the maple write
state no longer matched what the write was doing.  This was not an issue
as the values were previously not used, but to make the ma_wr_state usable
in future changes, the range min/max stored in the ma_wr_state for left
and right need to be consistent with the operation.
