    Infrastructure to detect sleep-inside-spinlock bugs.  Really only
    useful if compiled with CONFIG_PREEMPT=y.  It prints out a whiny
    message and a stack backtrace if someone calls a function which might
    sleep from within an atomic region.
    
    This patch generates a storm of output at boot, due to
    drivers/ide/ide-probe.c:init_irq() calling lots of things which it
    shouldn't under ide_lock.
    
    It'll find other bugs too.
