Change the idle task overslept warning printf to save stack space. The current warning uses CPRINTF which adds too much to the stack and overflows the idle stack. BUG=chrome-os-partner:33138, chrome-os-partner:36636 BRANCH=samus TEST=comment out the if (margin_us < 0) check and always print warning message. Without this CL stack overflows. With this CL, stack does not overflow and gets to 168/256, which is plenty of headroom considering the task doesn't do much.
