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.

-v2:
  * fix kern-doc and some codingstyle issues according to Jonathan's comment
  * patch 3/3 is rebased againest "[PATCH] mm/zswap: careful error path
    implementation in comp_prepare"[1]

  crypto: permit users to specify numa node of acomp hardware
  crypto: hisilicon/zip - permit users to specify NUMA node
  mm/zswap: allocate acomp on the numa node committing acomp_req
