  • Separate out and move chunk management (creation/desctruction and
    [de]population) code into percpu-vm.c which is included by percpu.c
    and compiled together. The interface for chunk management is defined
    as follows.

    * pcpu_populate_chunk - populate the specified range of a chunk
    * pcpu_depopulate_chunk - depopulate the specified range of a chunk
    * pcpu_create_chunk - create a new chunk
    * pcpu_destroy_chunk - destroy a chunk, always preceded by full depop
    * pcpu_addr_to_page - translate address to physical address
    * pcpu_verify_alloc_info - check alloc_info is acceptable during init

    Other than wrapping vmalloc_to_page() inside pcpu_addr_to_page() and
    dummy pcpu_verify_alloc_info() implementation, this patch only moves
    code around. This separation is to allow alternate chunk management
    implementation.
