@
@ mmap takes 6 parameters - ie more than can be passed in registers via the
@ regular syscall interface. Instead, parameters are passed on the stack.
@
@ On entry, the compiler will have already placed the fifth and sixth
@ parameters on the stack - all we need do here is push the first four and
@ call the syscall.
