7fcd36fbd3 Lock when setting PTE for kernel virual address 
We didn't have any lock variable to guard the manipulation of a PTE for
kernel virual address space. Note that we have one for user virtual
address space.

19fa391d4f Implement vfork system call 
It's implemented by making it issue clone system call internally with
the arguments of (SIGCHLD, 0, 0, 0, 0). The feature in which the caller
of vfork blocks until the child issues exit/execve is not implemented.
Refer to #233.

6dd5407b5f Return error when no core is available 
clone returns -EAGAIN when there is no vacant core.
In addition, clone tries to use the next vacant hyper-threading
core instead of trying to use next vacant hyper-threading core
of the next vacant physical core.
