similar to: [RFCv2 0/5] enable migration of driver pages

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

I sent a patch about page allocation for less fragmentation. http://permalink.gmane.org/gmane.linux.kernel.mm/130599 It proposes a page allocator allocates pages in the same pageblock for the drivers to move their unmovable pages. Some drivers which comsumes many pages and increases system fragmentation use the allocator to move their pages to decrease fragmentation. I think I can try another

Recently, I got many reports about perfermance degradation in embedded system(Android mobile phone, webOS TV and so on) and easy fork fail. The problem was fragmentation caused by zram and GPU driver mainly. With memory pressure, their pages were spread out all of pageblock and it cannot be migrated with current compaction algorithm which supports only LRU pages. In the end, compaction cannot
