Hi Mauro,
This single patch fixes setting the write parameter to 1 for
get_user_pages() on writable buffers. Without this using USERPTR buffers
with the dma-contig mem type will corrupt system memory.
This is directly applicable to fixes and master branches and should be
pulled into both.
The following changes since commit 4bad5d2d25099a42e146d7b18d2b98950ed287f5:
