Subject: [PATCH 1/4] mm: percpu: Generalize percpu related config
The HAVE_SETUP_PER_CPU_AREA/NEED_PER_CPU_EMBED_FIRST_CHUNK/
NEED_PER_CPU_PAGE_FIRST_CHUNK/USE_PERCPU_NUMA_NODE_ID configs,
which have duplicate definitions on platforms that subscribe it.
Move them into mm, drop these redundant definitions and instead
just select it on applicable platforms.
