	   ftp://ftp.*.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.3/2.3.99-pre7-pre3/classzone-18.gz

Btw, the path seem to be incorrect.  It should be:

/pub/linux/kernel/people/andrea/patches/v2.3/2.3.99-pre7-pre3/classzone-18.gz

:-)

One note after initial study.  I wish we could get rid of the
"map_count" thing you added to the page struct.  Currently, when
we turn off wait queue debugging, the page struct is an exact power
of 2 on both 64-bit and 32-bit architectures.  With the map_count
there now, it will not be an exact power of two in size on 32-bit
machines :-(
