[GIT PULL] additional MM updates for 5.19-rc1

[Andrew Morton]

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.
