[PATCH] move_pages: fix 32 -> 64 bit compat function

The definition of the third parameter is a pointer to an array of virtual
addresses which give us some trouble.  The existing code calculated the
wrong address in the array since I used void to avoid having to specify a
type.

I now use the correct type "compat_uptr_t __user *" in the definition of
the function in kernel/compat.c.

However, I used __u32 in syscalls.h.  Would have to include compat.h there
in order to provide the same definition which would generate an ugly
include situation.

On both ia64 and x86_64 compat_uptr_t is u32. So this works although
parameter declarations differ.
