[Linux-ia64] Integer to Pointer Cast Warnings when Building 2.4.17

["LAKSHMIPATHY,ARUN (HP-India,ex2)" <arun_lakshmipathy@hp.com>]

Hi,

I Get an integer to pointer typecast warning from some of the sources when
building the 2.4.17 kernel, I am using the base 2.4.17 kernel and the ia64
patch with no other patches, the kernel builds fine and comes up fine.
Wanted to be sure that this is not a cause for concern. Enclosed below is
the excerpt of the build o/p.

make[1]: Entering directory `/kernel/linux/arch/ia64/ia32'
sys_ia32.c: In function `sys32_brk':
sys_ia32.c:3824: warning: passing arg 1 of `__do_clear_user' makes pointer
from integer without a cast
