Yes, sorry. I messed it up. For now the patch can be ignored. I will 
re-send it once, all appearances of '__get_unaligned_cpu32' are removed. 
I have already send according patches for the 2 remaining files that 
still use it, namely 'include/linux/jhash.h' and 
'tools/include/linux/jhash.h'.

Sorry again.
