Christoph Lameter 906e0be197 page migration: Only migrate pages if allocation in the highest zone is possible ... Address spaces contain an allocation flag that specifies restriction on the zone for pages placed in the mapping. I.e. some device may require pages to be allocated from a DMA zone. Block devices may not be able to use pages from HIGHMEM. Memory policies and the common use of page migration works only on the highest zone. If the address space does not allow allocation from the highest zone then the pages in the address space are not migratable simply because we can only allocate memory for a specified node if we allow allocation for the highest zone on each node.
