<DIV><SPAN class=054063616-12022008><FONT face=Arial size=2>Instead of searching
some workaround, i'm going to perform the following "drastic"
solution:</FONT></SPAN></DIV>
<DIV><SPAN class=054063616-12022008> <FONT face=Arial size=2>-
remove __ptr64 attribute from all the functions of the
stack;</FONT></SPAN></DIV>
<DIV><SPAN class=054063616-12022008> <FONT face=Arial size=2>-
remove __ptr64 attribute from all the structures except the Ioctl
ones;</FONT></SPAN></DIV>
<DIV><SPAN class=054063616-12022008> <FONT face=Arial size=2>-
use PtrToPtr64 function while the assignment of __ptr64 Ioctl fields (only in
user space);</FONT></SPAN></DIV>
<DIV><SPAN class=054063616-12022008> <FONT face=Arial size=2>-
remove unnecessary castings, related to __ptr64 attriubute all over the code, if
any;</FONT></SPAN></DIV>
