    Subject[PATCH 0/9] sections: Unify kernel sections range check and use
    Date
    There are three head files(kallsyms.h, kernel.h and sections.h) which
    include the kernel sections range check, let's make some cleanup and
    unify them.

    1. cleanup arch specific text/data check and fix address boundary check in kallsyms.h
    2. make all the basic kernel range check function into sections.h
    3. update all the callers, and use the helper in sections.h to simplify the code
    4. use memory_intersects() in sections.h instead of private overlap for dma-debug

    Kefeng Wang (9):
    kallsyms: Remove arch specific text and data check
    kallsyms: Fix address-checks for kernel related range
    sections: Move and rename core_kernel_data() to is_kernel_data()
    sections: Move is_kernel_inittext() into sections.h
    kallsyms: Rename is_kernel() and is_kernel_text()
    sections: Add new is_kernel() and is_kernel_text()
    s390: kprobes: Use is_kernel() helper
    powerpc/mm: Use is_kernel_text() and is_kernel_inittext() helper
    dma-debug: Use memory_intersects() directly
