Subject: [PATCH] mips: Fix compilation warning


Fix the following compilation warning:

mm/page_alloc.c: In function 'free_reserved_area':
mm/page_alloc.c:5162: warning: passing argument 1 of 'virt_to_phys' makes pointer from integer without a cast
/home/ebsong/backup/linux_git/linux/arch/mips/include/asm/io.h:119: note: expected 'const volatile void *' but argument is
of type 'long unsigned int'
