Greg,
Here are the backports of the patches for the maple tree fixes from
6.3-rc6 for 6.1 and 6.2.
The patches differ with a few extra patches for the maple tree, and
changes to the mm code patch to work without the vma iterator change.

maple_tree: remove GFP_ZERO from kmem_cache_alloc() and
kmem_cache_alloc_bulk()
maple_tree: fix potential rcu issue
maple_tree: reduce user error potential
maple_tree: fix handle of invalidated state in mas_wr_store_setup()
maple_tree: fix mas_prev() and mas_find() state handling
maple_tree: fix mas_skip_node() end slot detection
maple_tree: be more cautious about dead nodes
maple_tree: refine ma_state init from mas_start()
maple_tree: detect dead nodes in mas_start()
maple_tree: fix freeing of nodes in rcu mode
maple_tree: remove extra smp_wmb() from mas_dead_leaves()
maple_tree: add smp_rmb() to dead node detection
