[PATCH v4 0/4] supplement of slab allocator removal

[sxwjean]

From: Xiongwei Song <xiongwei.song@xxxxxxxxxxxxx>

Hi,

Patch 1 is to remove an unused parameter. It has a longer history, please
see the change history inside the patch.

---
Patch 2 is to replace slub_$params with slab_$params.
Vlastimil Babka pointed out we should use "slab_$param" as the primary
prefix for long-term plan. Please see [1] for more information.

I did the basic tests with qemu, which passed values by sl[au]b_max_order,
sl[au]b_min_order, sl[au]b_min_objects and sl[au]b_debug in command line.
The values looks correct by printing them out before calculating orders.

---
Patch 3 is to replace slub_$params in Documentation/mm/slub.rst based on
the changes of patch 2.

---
Patch 4 is original patch 3. It is not related to slab allocator removal.
It's to correct the description of default value of slab_min_objects in
Documentation/mm/slub.rst. 

---
This series is based on [2].
