Subject: [PATCH mm-unstable 0/5] Switch zswap to object read/write APIs

This patch series updates zswap to use the new object read/write APIs
defined by zsmalloc in [1], and remove the old object mapping APIs and
the related code from zpool and zsmalloc.

This depends on the zsmalloc/zram series introducing the APIs [1] and
the series removing zbud and z3fold [2].

Yosry Ahmed (5):
  mm: zpool: Add interfaces for object read/write APIs
  mm: zswap: Use object read/write APIs instead of object mapping APIs
  mm: zpool: Remove object mapping APIs
  mm: zsmalloc: Remove object mapping APIs and per-CPU map areas
  mm: zpool: Remove zpool_malloc_support_movable()
