kmem_cache is a frequently used data in kernel. During the code reading, I
found maybe we could save some space in some cases.

1. On 64bit arch, type int will occupy a word if it doesn't sit well.
2. cpu_slab->partial is just used when CONFIG_SLUB_CPU_PARTIAL is set
3. cpu_partial is just used when CONFIG_SLUB_CPU_PARTIAL is set, while just
save some space on 32bit arch.

Wei Yang (3):
  mm/slub: pack red_left_pad with another int to save a word
  mm/slub: wrap cpu_slab->partial in CONFIG_SLUB_CPU_PARTIAL
  mm/slub: wrap kmem_cache->cpu_partial in config
    CONFIG_SLUB_CPU_PARTIAL
