    You are missing the point. There are several macros that use
    __ex_table. Unless it can be guaranteed that no current or future use
    of *any* of those macros will be in an __init section then we must not
    assume that the exception table is sorted.

    Exception table is not the only one that is assumed to be sorted,
    get8_unaligned_check is not the only macro that uses __ex_table. Both
    are examples of tables and code where we assume, but do not validate, a
    sorted table.
