The problem is that __get_free_pages returns an unsigned long and mca_bootmem, via alloc_bootmem(), returns a void *. format_mca_init_stack takes the void *, and it's also used with __pa(), but that casts it to long anyway. This results in the following build warning: arch/ia64/kernel/mca.c:1898: warning: assignment makes pointer from integer without a cast This patch casts the return of __get_free_pages to a void * to avoid the warning.
