arm64/kernel: rename module_emit_adrp_veneer->module_emit_veneer_for_adrp
Commit a257e02579e ("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 bd8b22d2888e ("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.
