+ * This is for COMPATIBILITY with Linux/x86 only.  Linux/Alpha system

+ * mistaken as error numbers).  However, C allows to return only one
+ * value so the interface below folds the error indication passed in
+ * a3 back into v0: it sets v0 to -errno if an error occurs.  Thus,
+ * no negative 64bit numbers can be returned.  To avoid this problem,
+ * use assembly stubs wherever possible/convenient.
+ *
+ * Usage:
+ *
+ * long	syscall(syscall_number, arg1, arg2, arg3, arg4, arg5)
+ *
+ * syscall_number = the index of the system call we're invoking
+ * arg1-arg5 = up to 5 integer arguments to the system call
+ *
+ * We need to do some arg shifting: the kernel expects the
+ * syscall number in v0 and the first five args in a0-a4.
