    arm64/kernel: rename module_emit_adrp_veneer->module_emit_veneer_for_adrp · ed231ae3
    Kim Phillips authored
    Commit a257e025 ("arm64/kernel: don't ban ADRP to work around
    Cortex-A53 erratum #843419") introduced a function whose name ends with
    "_veneer".
    
    This clashes with commit bd8b22d2 ("Kbuild: kallsyms: ignore veneers
    emitted by the ARM linker"), which removes symbols ending in "_veneer"
    from kallsyms.
    
    The problem was manifested as 'perf test -vvvvv vmlinux' failed,
    correctly claiming the symbol 'module_emit_adrp_veneer' was present in
    vmlinux, but not in kallsyms.
    
    ...
        ERR : 0xffff00000809aa58: module_emit_adrp_veneer not on kallsyms
    ...
        test child finished with -1
        ---- end ----
        vmlinux symtab matches kallsyms: FAILED!
    
    Fix the problem by renaming module_emit_adrp_veneer to
    module_emit_veneer_for_adrp.  Now the test passes.
