From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Mahoney Date: Thu, 24 Feb 2011 22:23:09 +0000 Subject: [PATCH] ia64/mca: Fix cast from integer to pointer warning Message-Id: <4D66DA4D.4020609@suse.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Linux Kernel Mailing List Cc: linux-ia64@vger.kernel.org, Tony Luck 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 This patch casts the return of __get_free_pages to a void * to avoid the warning.
