85 * __MAP - apply a macro to syscall arguments
86 * __MAP(n, m, t1, a1, t2, a2, ..., tn, an) will expand to
87 * m(t1, a1), m(t2, a2), ..., m(tn, an)
88 * The first argument must be equal to the amount of type/name
89 * pairs given. Note that this list of pairs (i.e. the arguments
90 * of __MAP starting at the third one) is in the same format as
91 * for SYSCALL_DEFINE<n>/COMPAT_SYSCALL_DEFINE<n>
