0942bf0ce0 make dkprintf() evaluate its parameters always 
Parameters of dkprintf() should be evaluated even if dkprintf() is
disabled.  Because this enables to find expression of parameter obsolete
and to avoid unnecessary compiler warnings such as "unused variable".

b2cab453f1 clone(): do not allow setting CLONE_THREAD and CLONE_VM separately 
XXX: When CLONE_VM is set but CLONE_THREAD is not the new thread is
meant to have its own thread group, i.e., when calling exit_group()
the cloner thread wouldn't be killed. However, this is a problem on
the Linux side because we do not invoke clone in mcexec when threads
are created. Thus, currently no support for this combination is
provided.

ea02628f2b Add reboot and shutdown script for builtin-x86 
It decides the number of cores for McKernel by looking into the
"SHIMOS: CPU Status:" line of dmesg. It sets the amount of memory for
McKernel to one urth of the total memory obtained by "free -g".

d2cb890cdd idle(): recheck runq just before cpu status check 
There is a problem which causes wait4(2) hang when wait4(2) called by a
process races with its child process termination.
This is a quick fix for this problem. See idle().
