cgroup/cpuset-v1: Add deprecation messages to memory_spread_page and memory_spread_slab
There is MPOL_INTERLEAVE for user explicit allocations.
Deprecate spreading of allocations that users carry out unwittingly.
Use straight warning level for slab spreading since such a knob is
unnecessarily intertwined with slab allocator.
