Hello, This series try to enable migration of non-LRU pages, such as driver's page. My ARM-based platform occured severe fragmentation problem after long-term (several days) test. Sometimes even order-3 page allocation failed. It has memory size 512MB ~ 1024MB. 30% ~ 40% memory is consumed for graphic processing and 20~30 memory is reserved for zram. I found that many pages of GPU driver
