Building an arm64 defconfig with clang's integrated assembler, this error occurs: <instantiation>:2:2: error: unrecognized instruction mnemonic _ASM_EXTABLE 9999b, 9f ^ arch/arm64/mm/cache.S:50:1: note: while in macro instantiation user_alt 9f, "dc cvau, x4", "dc civac, x4", 0 ^ While GNU as seems fine with case-sensitive macro instantiations, clang doesn't, so use the actual macro name (_asm_extable) as in the rest of the file. Also checked that the generated assembly matches the GCC output. Reviewed-by:
