Hi,

Patch 1 is to remove an unused parameter. This patch actually is v3, but
it is not reasonable to add v3 tag in the cover letter, so I put 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.

This patch is to do that. However, the patch is big, I'm not sure if
everything is proper in it, so I added "RFC" in the patch title. For more
information please see the commit message of patch.

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.

One thing I'm not sure about the forth parameter of __setup_param(),
Is it correct to set the parameter to 0 directly?

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