Hi, this series adds mapping color control to the generic kmap code, allowing architectures with aliasing VIPT cache to use high memory. There's also use example of this new interface by xtensa. Changes since v3: - drop #include <asm/highmem.h> from mm/highmem.c as it's done in linux/highmem.h; - add 'User-visible effect' section to changelog.
