include\asm-i386\Pgtable.h中
/* Caches aren't brain-dead on the intel. */ //这句话什么意思 :ask ?
#define flush_cache_all() do { } while (0)
#define flush_cache_mm(mm) do { } while (0)
#define flush_cache_range(mm, start, end) do { } while (0)
#define flush_cache_page(vma, vmaddr) do { } while (0)
#define flush_page_to_ram(page) do { } while (0)
#define flush_icache_range(start, end) do { } while (0)
