mm: Kconfig: reorganize misplaced mm options
After commits 7b42f1041c98 ("mm: Kconfig: move swap and slab config options to the MM section") and 519bcb797907 ("mm: Kconfig: group swap, slab, hotplug and thp options into submenus") we now have nicely organized mm related config options. I have noticed some that were still misplaced, so this moves them from various places into the new structure: VM_EVENT_COUNTERS, COMPAT_BRK, MMAP_ALLOW_UNINITIALIZED to mm/Kconfig and general MM section. SLUB_STATS to mm/Kconfig and the slab submenu. DEBUG_SLAB, SLUB_DEBUG, SLUB_DEBUG_ON to mm/Kconfig.debug and the Kernel hacking / Memory Debugging submenu.

-config DEBUG_SLAB
- bool "Debug slab memory allocations"
- depends on DEBUG_KERNEL && SLAB
- help
- Say Y here to have the kernel do limited verification on memory
- allocation as well as poisoning memory on free to catch use of freed
- memory. This can make kmalloc/kfree-intensive workloads much slower.

-config SLUB_DEBUG_ON
- bool "SLUB debugging on by default"
- depends on SLUB && SLUB_DEBUG
- default n
- help
- Boot with debugging on by default. SLUB boots by default with
- the runtime debug capabilities switched off. Enabling this is
- equivalent to specifying the "slub_debug" parameter on boot.
- There is no support for more fine grained debug control like
- possible with slub_debug=xxx. SLUB debugging may be switched
- off in a kernel built with CONFIG_SLUB_DEBUG_ON by specifying
- "slub_debug=-".
-
-config SLUB_STATS
- default n
- bool "Enable SLUB performance statistics"
- depends on SLUB && SYSFS
- help
- SLUB statistics are useful to debug SLUBs allocation behavior in
- order find ways to optimize the allocator. This should never be
- enabled for production use since keeping statistics slows down
- the allocator by a few percentage points. The slabinfo command
- supports the determination of the most active slabs to figure
- out which slabs are relevant to a particular load.
- Try running: slabinfo -DA
