I applied this, thanks.

General note to everybody: When sending patches, it makes my life easier
if they apply with "patch -p1" and if you copy the linux-ia64 list.

And though it doesn't apply in this case because 2.5 has perfmon2, it
never hurts to diff the files you touch with the corresponding files
in linux-2.5.  (I do that routinely, and if your patch introduces
spurious whitespace differences, I have to clean them up by hand.)
