Subject: [PATCH 0/3] crypto: allow users to specify acomp hardware from a desired NUMA node

For a typical Linux server, probably there are several hardware modules.
For example, numa node0 has a compressor, numa node2 has a same module.
Some drivers are automatically using the module near the CPU calling
acomp_alloc.
But it isn't necessarily correct. Just like memory allocation API like
kmalloc and kmalloc_node. Similar optimization may be done for crypto.

Barry Song (3):
  crypto: permit users to specify numa node of acomp hardware
  crypto: hisilicon/zip - permit users to specify NUMA node
  mm/zswap: specify the NUMA node of acomp to use local compressors
  [mm/zswap patch is on top of linux-next tree]
