PATCH 1/1 New zone ZONE_EASY_RECLAIM take 3. (disable gfp_easy_reclaim bit)[5/5]

This is to disable __GFP_EASY_RECLAIM flag at add_to_page_cache(). If this patch is not applied, cache_grow() checks and call BUG(), at here.

	if (flags & ~(SLAB_DMA|SLAB_LEVEL_MASK|SLAB_NO_GROW))
		BUG();

This patch is to solve it.
