Hi all,
This series here implements an interface to enable cpu access from the kernel
context to dma_buf objects. The main design goal of this interface proposal is
to enable buffer objects that reside in highmem.
Comments, flames, ideas and questions highly welcome. Althouhg I might be a bit
slow in responding - I'm on conferences and vacation the next 2 weeks.
Cheers, Daniel

dma-buf: add support for kernel cpu access
dma_buf: Add documentation for the new cpu access support
