Merge tag 'omap-for-v3.8/cleanup-headers-prepare-multiplatform-v3-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/headers

From Tony Lindgren <tony@atomide.com>:

These changes deal with the issues of relative includes
introduced by the earlier clean-up and clean up few more
things for enabling multiplatform support.

The multiplatform kernel has been booted on omaps on
top of this branch with the work-in-progress patches
applied manually.

We cannot yet enable the multiplatform support though.
We still need the common clock framework patches, some
solution for dma-omap.h, and serial-omap.h moved before
we can enable it.

* tag 'omap-for-v3.8/cleanup-headers-prepare-multiplatform-v3-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP: Remove omap_init_consistent_dma_size()
