    x86, extable: Remove open-coded exception table entries in arch/x86/um/checksum_32.S

    Remove open-coded exception table entries in arch/x86/um/checksum_32.S,
    and replace them with _ASM_EXTABLE() macros; this will allow us to
    change the format and type of the exception table entries.
