Pretty much the final flush here. Mel's "Drain remote per-cpu
directly" series might be stabilized later in the merge window.
There's a merge conflict in init/Kconfig. We resolved that by removing
the VM_EVENT_COUNTERS..MMAP_ALLOW_UNINITIALIZED entries.
And another in lib/Kconfig.debug. Similarly resolved by removing the
DEBUG_SLAB..SLUB_STATS entries.
I'll shortly be resurrecting Liam's maple-tree patchset for additional
stabilization and a view to merge that up for 5.20. And shortly after
that I'll bring in Yu Zhau's multigen LRU work to get that some
linux-next testing and hopefully reviewer provocation.
