这段代码是用于在AGP中分配一个页面的函数。具体来说，它使用GFP_KERNEL和GFP_DMA32标志分配了一个页面，并将其清零。然后将页面映射到AGP孔中，并递增了页面的引用计数。最后，它返回指向分配的页面的指针。

为了注释掉这个函数，可以将整个函数体的代码用 /* 和 */ 包围起来，或者将函数名和花括号之间的代码删除。例如：

/*
struct page *agp_generic_alloc_page(struct agp_bridge_data *bridge) {

// This function is used to allocate one page of memory for use by AGP.

// It allocates a page with GFP_KERNEL and GFP_DMA32 flags and zeroes it out.

// It then maps the page into the AGP aperture and increments the reference count.

// Finally, it returns a pointer to the allocated page.

	struct page * page;

	page = alloc_page(GFP_KERNEL | GFP_DMA32 | __GFP_ZERO);

	if (page == NULL)

		return NULL;

	map_page_into_agp(page);

	get_page(page);

	atomic_inc(&agp_bridge->current_memory_agp);

	return page;

}
