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".

fix.

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().

a9bebf1e14 Make idle loop not miss a chance to schedule 
Prevents the case where McKernel misses one chance to schedule a
task when an interrupt occurs just after enabling interrupt and
just before executing "halt" in the idle loop (in kernel/process.c).
