From 1ad8267b5d86dce44f538953dab1944c0b6bf032 Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Thu, 24 Feb 2011 17:23:09 -0500 Subject: [PATCH] mca.c: Fix cast from integer to pointer warning 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.
