[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.
