| /* Below comes the architecture-specific code. For each architecture, we have |
| * the syscall declarations and the _start code definition. This is the only |
| * global part. On all architectures the kernel puts everything in the stack |
| * before jumping to _start just above us, without any return address (_start |
| * is not a function but an entry pint). So at the stack pointer we find argc. |
| * Then argv[] begins, and ends at the first NULL. Then we have envp which |
| * starts and ends with a NULL as well. So envp=argv+argc+1. |
