    Subject[PATCH v3 13/14] include/linux/compiler.h: remove unused KENTRY macro
    From
    This macro is not used throughout the kernel. Delete it rather than
    update the __section to be a fully spelled out
    __attribute__((__section__())) to avoid
    https://bugs.llvm.org/show_bug.cgi?id=42950.

    - * KENTRY - kernel entry point
    - * This can be used to annotate symbols (functions or data) that are used
    - * without their linker symbol being referenced explicitly. For example,
    - * interrupt vector handlers, or functions in the kernel image that are found
    - * programatically.
    - *
    - * Not required for symbols exported with EXPORT_SYMBOL, or initcalls. Those
    - * are handled in their own way (with KEEP() in linker scripts).
    - *
    - * KENTRY can be avoided if the symbols in question are marked as KEEP() in the
    - * linker script. For example an architecture could KEEP() its entire
    - * boot/exception vector code rather than annotate each function and data.
