[PATCH v7 02/14] mm: add zone device coherent type memory support

2022-06-28 Thread Alex Sierra
Device memory that is cache coherent from device and CPU point of view. This is used on platforms that have an advanced system bus (like CAPI or CXL). Any page of a process can be migrated to such memory. However, no one should be allowed to pin such memory so that it can always be evicted.
