I was wrong, with the linux/bigmem.h trick all other arch should be just fine ;). I did a preliminary cleanup. mm/page_alloc.c still uses some #ifdef but they are not trivally removable, for example: +#ifdef CONFIG_BIGMEM +#define BIGMEM_LISTS_OFFSET NR_MEM_LISTS +static struct free_area_struct free_area[NR_MEM_LISTS*2]; +#else static struct free_area_struct free_area[NR_MEM_LISTS]; +#endif The cleanedup patch (bigmem-2.3.13-N) is attached. andrea@laser:~/kernel-patches/2.3.13 > ls -l bigmem-2.3.13-[NM] -rw-r--r-- 1 andrea andrea 32416 Aug 17 01:28 bigmem-2.3.13-M -rw-r--r-- 1 andrea andrea 30779 Aug 17 16:01 bigmem-2.3.13-N (2kbyte removed from the cleanup) Thanks.

bigmem without #ifdef CONFIG_BIGMEM all over the place
