            atomic_nand_32.S atomic_nand_64.S atomic_nand_8.S

Log Message:
Fix the logic operation for atomic_nand_{8,16,32,64}

>From the gcc docs the operations are as follows

 { tmp = *ptr; *ptr = ~(tmp & value); return tmp; }   // nand
 { tmp = ~(*ptr & value); *ptr = tmp; return *ptr; }   // nand

yes, this is really rather strange.
