  vfio: fix documentation (2013-09-05 16:36:21 -0600)

----------------------------------------------------------------
VFIO updates include safer default file flags for VFIO device fds,
an external user interface exported to allow other modules to hold
references to VFIO groups, a fix to test for extended config space
on PCIe and PCI-x, and new hot reset interfaces for PCI devices
which allows the user to do PCI bus/slot resets when all of the
devices affected by the reset are owned by the user.

For this last feature, the PCI bus reset interface, I depend on
changes already merged from Bjorn's PCI pull request.  I therefore
merged my tree up to commit cb3e433, which I think was the correct
action, but as Stephen Rothwell noted, I failed to provide a commit
message indicating why the merge was required.  Sorry for that.
Thanks,
Alex
