For the record I'm posting here the final version of this patch, in case 
it gets applied. It adds minor stylistic fixes, plus a small change in 
alloc_pool sizes. Any further testing I do will be posted under this 
thread.

  The previously posted Changelog applies, with the following addition:

 	(df_scan_alloc): Rounded up allocation pools size, reduced the
 	mw_reg_pool size, it was unnecessarily large.

Paolo, did I assume correctly that the mw_reg_pool is significantly 
smaller than the rest? That was the case on i386, I assumed it would be 
similar in other arch as well.


Thanks,
Dimitris
