    Subject[07/26] [IA64] mca.c: Fix cast from integer to pointer warning
    2.6.33-longterm review patch.  If anyone has any objections, please let us know.


    From: Jeff Mahoney <>

    commit c1d036c4d1cb00b7e8473a2ad0a78f13e13a8183 upstream.

    ia64_mca_cpu_init has a void *data local variable that is assigned
    the value from either __get_free_pages() or mca_bootmem(). 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

    Cast the return of __get_free_pages to a void * to avoid
    the warning.
