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