OK thanks, I'm queueing it for 2.4.37.

OK, it makes sense. Another solution could have been to use ~0 instead of
(unsigned long)-1, but at least using -1 is easier to match with other
places. It would be kind to send the same patch for 2.6-mainline too.

Amusing. Interestingly, I mostly build my kernels with 2.95.3 too and never
got this funny thing. But I think that 2.95.3 has existed in so many flavors
that all we know is that it's based on some 2.95.[234] + more or less a ton
of patches.

I have no worries about this :-)

OK, I'm queueing your patches.

Thanks Steve!
