This should be & ~GFP_ZONEMASK
Actually, we should probably have a function to clear those bits rather
than have every driver manipulating the gfp mask like this. Maybe
#define gfp_normal(gfp) ((gfp) & ~GFP_ZONEMASK)
return (unsigned long)kmem_cache_alloc(pool->handle_cachep,
- gfp & ~(__GFP_HIGHMEM|__GFP_MOVABLE));
+ gfp_normal(gfp));
