kernel - Make the x86-64 double-fault exception operational
* Finish implementing the double-fault exception. Only cpu0 implemented
the proper interrupt stack configuration before. Now all cpus implement
the proper interrupt stack.
* For x86-64 use the idle thread stack for the double-fault exception
stack for now (probably not the best idea but better than nothing).
* For both i386 and x86-64, when a double fault occurs, report whether
it is a generic double fault or whether it is due to a kernel stack
guard.
