    mm/page_alloc.c: pull out init code from build_all_zonelists · 061f67bc
    Rasmus Villemoes authored
    Pulling the code protected by if (system_state == SYSTEM_BOOTING) into
    its own helper allows us to shrink .text a little. This relies on
    build_all_zonelists already having a __ref annotation. Add a comment
    explaining why so one doesn't have to track it down through git log.
    The real saving comes in 3/5, ("mm/mm_init.c: Mark mminit_verify_zonelist
    as __init"), where we save about 400 bytes
