This patch stops warning message introduced by the "[patch 25/44]
ia64: use generic bitops" which replaces __set_bit() family to
generic one.
But I realize that I can't replace to generic one for ia64.
Because __set_bit() family are using the pointer to __u32, but
generic __set_bit() family are using the pointer to unsigned long.
So the patch 25/44 is wrong and the change above is unnessesary.
Thanks
