call dispatch. There are three entry points:
```
  func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
  func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
  func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)

The first and second are the standard ones; they differ only in how many
arguments can be passed to the kernel. The third is for low-level use by the
