-/* Syscalls for AARCH64 :
- * - registers are 64-bit
- * - stack is 16-byte aligned
- * - syscall number is passed in x8
- * - arguments are in x0, x1, x2, x3, x4, x5
- * - the system call is performed by calling svc 0
- * - syscall return comes in x0.
- * - the arguments are cast to long and assigned into the target registers
- * which are then simply passed as registers to the asm code, so that we
- * don't have to experience issues with register constraints.
- *
- * On aarch64, select() is not implemented so we have to use pselect6().
