Move the initialization of ipoib_neigh's skb_queue into
ipoib_neigh_alloc(), since commit 2745b5b7 ("IPoIB: Fix skb leak when
freeing neighbour") will make iterate over the skb_queue to free any
packets left over when freeing the ipoib_neigh structure.
This fixes a crash when freeing ipoib_neigh structures allocated in
ipoib_mcast_send(), which otherwise don't have their skb_queue
initialized.

This patch implements the interposing DMA mapping functions to allow
support for IOMMUs and remove the dependence on phys_to_virt() and

The QLogic InfiniPath HCAs use programmed I/O instead of HW DMA.
This patch allows a verbs device driver to interpose on DMA mapping
function calls in order to avoid relying on bus_to_virt() and
phys_to_virt() to undo the mappings created by dma_map_single(),
dma_map_sg(), etc.

During connection establishment, the passive side of a connection can
receive messages from the active side before the connection event has
been delivered to the user. Allow the passive side to send messages
in response to received data before the event is delivered. To handle
the case where the connection messages are lost, a new rdma_notify()
function is added that users may invoke to force a connection into the
established state.

Commit 51f65ebc ("IB/ipath - program intconfig register using new HT
irq hook"), which fixed interrupts for HyperTransport HCAs, broke PCI
Express HCAs, because for those HCAs, the driver uses the value of
pdev->irq before pci_enable_msi() and ends up getting a totally bogus
IRQ number. Fix this by using the value of pdev->irq after
pci_enable_msi().

ib_flush_fmr_pool() stashes away the request generation number
properly, but then goes ahead and rereads it every time it tests
whether the flush generation number has caught up. This means that
there is a theoretical possibility of livelock, if the request
generation number keeps getting bumped and the flush generation number
never catches up. The fix is simple: use the request generation
number read at the beginning of the function.
Also, atomic_inc() followed by atomic_read() can be replaced with
atomic_int_return(). There's no real requirement for atomicity here
but we might as well shrink the code.
This bug was discovered using David Binderman's list of "set but never
used" warnings from icc.

Modify the OCFS2 handshake to ensure essential timeouts are configured
identically on all nodes.
Only allow changes when there are no connected peers
Improves the logic in o2net_advance_rx() which broke now that
sizeof(struct o2net_handshake) is greater than sizeof(struct o2net_msg)
Included is the field for userspace-heartbeat timeout to avoid the need for
further protocol changes.
Uses a global spinlock to ensure the decisions to update configfs entries
are made on the correct value. The region covered by the spinlock when
incrementing the counter is much larger as this is the more critical case.

This allows users to format an ocfs2 file system with a special flag,
OCFS2_FEATURE_INCOMPAT_LOCAL_MOUNT. When the file system sees this flag, it
will not use any cluster services, nor will it require a cluster
configuration, thus acting like a 'local' file system.
