Subject: [PATCH v4 0/2] mm/highmem: make kmap cache coloring aware

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.

  mm/highmem: make kmap cache coloring aware
  xtensa: support aliasing cache in kmap
