[PATCH 0/2] Fix mas_alloc_cyclic retry

[Liam R. Howlett]

This is a follow-up patch and test for Yang Erkun.  lore seems to have
eaten the original email [1], so I'll add akpm's link as well [2].

Patch 1 applies on top of Yang Erkun's fix, so feel free to squash it
in.

Patch 2 adds a test to the maple tree infrastructure that will catch the
issue if it comes back.
