Currently tools like ip and ifconfig report incorrect state for cxgb4
interfaces that are up but do not have link and do so until first link
establishment. This is because the initial netif_carrier_off call is
before register_netdev and it needs to be after to be fully effective.
Fix this by moving netif_carrier_off into .ndo_open.

Commit e462c448fdc8 ("pipe: use event aware wakeups") optimized the pipe
event wakeup calls to avoid wakeups if the events do not match the
requested set.
However, the optimization was buggy, in that it didn't actually use the
correct sets for the events: when we make room for more data to be
written, the pipe poll() routine will return both the POLLOUT _and_
POLLWRNORM bits. Similarly for read.
And most critically, when a pipe is released, that will potentially
result in POLLHUP|POLLERR (depending on whether it was the last reader
or writer), not just the regular POLLIN|POLLOUT.
This bug showed itself as a hung gnome-screensaver-dialog process, stuck
forever (or at least until it was poked by a signal or by being traced)
in a poll() system call.

During system suspend, the "wait for ring buffer to empty" loop would
always time out after three seconds, because the faster cached ring
buffer head read would always return zero. Force the slow-and-careful
PIO read on all but the first iterations of the loop to fix it.
This also removes the unused (and useless) 'actual_head' variable that
tried to approximate doing this, but did it incorrectly.

If there is a receive timeout without any active
requests, we can tell the connection was idle and
ignore the timeout.
If there are active requests for which we expect
to receive a reply we close the connection.
This makes it possible to set an upper bound on
the time a usbip device may be unresponsive.
This is a workaround for the lack of heart-beat
messages in the USBIP protocol.
Extending the protocol would break compatibility
with all previous stub versions, so this seems like
the lesser evil.

The stub driver expects to access the usb interface
and usb device structures even if the device has been
disconnected in the meantime.
This change gets a reference to them in the stub probe
function using usb_get_intf()/usb_get_dev() and drops them
in the disconnect function.
This fixes an oops observed with a Logic Controls Line
display (0fa8:a030) which disconnects itself when it is

Regression since commit 10389536742c, "firewire: core: check for 1394a
compliant IRM, fix inaccessibility of Sony camcorder":
The camcorder Canon MV5i generates lots of bus resets when asynchronous
requests are sent to it (e.g. Config ROM read requests or FCP Command
write requests) if the camcorder is not root node. This causes drop-
outs in videos or makes the camcorder entirely inaccessible.
https://bugzilla.redhat.com/show_bug.cgi?id=633260
Fix this by allowing any Canon device, even if it is a pre-1394a IRM
like MV5i are, to remain root node (if it is at least Cycle Master
capable). With the FireWire controller cards that I tested, MV5i always
becomes root node when plugged in and left to its own devices.

It's possible that when we access the ByteCount that the alignment
will be off. Most CPUs deal with that transparently, but there's
usually some performance impact. Some CPUs raise an exception on
unaligned accesses.
Fix this by accessing the byte count using the get_unaligned and
put_unaligned inlined functions. While we're at it, fix the types
of some of the variables that end up getting returns from these
functions.

Invalidate inode mapping if we don't have at least Level II oplock in
cifs_strict_fsync. Also remove filemap_write_and_wait call from cifs_fsync
because it is previously called from vfs_fsync_range. Add file operations'
structures for strict cache mode.

On strict cache mode when we close the last file handle of the inode we
should set invalid_mapping flag on this inode to prevent data coherency
problem when we open it again but it has been modified on the server.

This partially reverts commit da8aeb92d4853f37e281f11fddf61f9c7d84c3cd
("ACPI / Battery: Update information on info notification and resume"),
which causes a hang on resume on at least some machines.
This bug was bisected on an ASUS EeePC 901, which hangs at resume time
if we do that "acpi_battery_refresh(battery)" in the battery resume
function.
Rafael suspects we'll still need to refresh the sysfs files upon resume,
but that that can be done from a PM notifier (that will run after
thawing user space).

Lately, mailbox callbacks have been replaced by notifier block
call chains, this needs to be changed in the users of mailbox,
otherwise compilation will break due to missing parameters.
For this new change to work, io_mbox_msg needs to be compatible
with the notifier_call definition.

The ni_labpc driver module only requests a shared IRQ for PCI devices,
requesting a non-shared IRQ for non-PCI devices.
As this module is also used by the ni_labpc_cs module for certain
National Instruments PCMCIA cards, it also needs to request a shared IRQ
for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus
controller.

IVA MMU can manage up to 4GB of address space through its page tables,
given that it's L1 is divided into 1MB sections it requires at least
16KB for its table which represents 4096 entries of 32 bits each.
Previously, only 1GB was being handled by setting the page table size
to 4KB, any virtual address beyond of the L1 size used, would fall
into memory that does not belong to L1 translation tables, leading to
unpredictable results.
So, set the L1 table size to cover the entire MMU range (4GB) whether
is meant to be used or not.

The original code called input_free_device(rmi4_data->input_dev) after
input_unregister_device(rmi4_data->input_dev) and that's a double free.
This is described in the comments to input_unregister_device().
The normal way to handle this is to make input_register_device() the
last function in the probe which can fail. That way you can avoid the
call to input_unregister_device() entirely.

Removed the call to netif_stop_queue() in netvsc_probe() as
the queue is not initialized at that point and further call
to it after queue initialization is really not necessary.
This change was prompted after an upstream change went into
2.6.37 (netif_tx_stop_queue) that now checks if netif_stop_queue
is called before register with netdev is done.
This will eliminate the warning message to the log when hv_netvsc
driver starts up.
