Hi,

	This turns hard coded limit on maximum physical pages
per-zspage into a config option. It also increases the default
limit from 4 to 8.

Sergey Senozhatsky (4):
  zsmalloc: rework zspage chain size selection
  zsmalloc: skip chain size calculation for pow_of_2 classes
  zsmalloc: make zspage chain size configurable
  zsmalloc: set default zspage chain size to 8
