From bb3ec6b08396bbd631b6441102dd1c3d89cbc576 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 22 May 2013 12:18:47 +0200 Subject: [PATCH] mm: Fix virt_to_page() warning MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit virt_to_page() is typically implemented as a macro containing a cast so that it will accept both pointers and unsigned long without causing a warning. But MIPS virt_to_page() uses virt_to_phys which is a function so passing an unsigned long will cause a warning: CC mm/page_alloc.o mm/page_alloc.c: In function ‘free_reserved_area’: mm/page_alloc.c:5161:3: warning: passing argument 1 of ‘virt_to_phys’ makes pointer from integer without a cast [enabled by default] arch/mips/include/asm/io.h:119:100: note: expected ‘const volatile void *’ but argument is of type ‘long unsigned int’ All others users of virt_to_page() in mm/ are passing a void *.
