[Patch] New zone ZONE_EASY_RECLAIM take 2[5/5]

[Patch] New zone ZONE_EASY_RECLAIM take 2[5/5]

[Yasunori Goto]

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.
