Makes sense probably - but please send a patch against -tip as 
we've got quite many changes queued up in that area and your 
patch does not apply cleanly:

 patching file kernel/smp.c
 Hunk #1 FAILED at 222.
 Hunk #2 FAILED at 229.
 Hunk #3 FAILED at 325.
 Hunk #4 FAILED at 344.
 4 out of 4 hunks FAILED -- rejects in file kernel/smp.c

Thanks,

	Ingo
