Virtual Contiguous Memory Manager. The version posted by Zach can be found at: <http://article.gmane.org/gmane.linux.kernel.mm/50090>. It is an API for managing IO MMU and IO MMU mappings.

Contiguous Memory Manager. The v4 version can be found at <http://marc.info/?l=linux-mm&m=128229799415817&w=2>. It is an API for allocating large, physically contiguous blocks of memory.
I haven't expected that anyone who haven't already participated in the discussion about CMA and VCMM will get interested by this patchset so I was a bit vague in the cover letter. Sorry about that.

Ignore the code then and look just at the documentation, please. I wanted to post what I have to receive comments about the general idea and not necessarily the code itself. Code is just a mean to show how I see the implementation of the idea described in the documentation. Because of all that, I marked the patchset as a RFC rather than a PATCH.
