Put the flag after the spinlock, not after the "list_head".

Also, we'd need to make it 

	unsigned short flag:1;

_and_ change spinlock_types.h to make the spinlock size actually match the 
required size (right now we make it an "unsigned int slock" even when we 
actually only use 16 bits). See the 

	#if (NR_CPUS < 256)

code in <asm-x86/spinlock.h>.
