The following patch enables SMC911x support to work on the OMAP LDP

This is done by
1) Wake up lock waiters when we close the master file descriptor.
Not when the master structure is removed, since the latter
requires the waiters themselves to release the refcount on the
master structure -> Deadlock.
2) Send a SIGTERM to all clients waiting for the lock.
Normally these clients will get a SIGPIPE when the X server dies,
but clients may also spin trying to grab the DRM lock, without
getting any sort of notification.

The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up. This patch adds the device id to cdc_ether.c as a workaround.
Ericsson has provided a "class" driver for this device:
http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094
But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c. See also

This is 2nd attempt to implement the initialization/reading of MAC address
from EEPROM. The first used PCI's VPD and there were some problems, some
devices are not able to read EEPROM content by VPD. The 2nd one uses direct
access to EEPROM through bit-banging interface and my testing results seem
to be much better.
I tested 5 systems each with different Realtek NICs and I didn't find any
problem. AFAIK Francois's NICs also works fine.
Original description:
This fixes the problem when MAC address is set by ifconfig or by
ip link commands and this address is stored in the device after
reboot. The power-off is needed to get right MAC address.
This is problem when Xen daemon is running because it renames the device
name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF.
After reboot the device is still using FE:FF:FF:FF:FF:FF.

The musb_h_disable() routine can oops in some cases:
- It's not safe to read hep->hcpriv outside musb->lock,
since it gets changed on completion IRQ paths.
- The list iterators aren't safe to use in that way;
just remove the first element while !list_empty(),
so deletions on other code paths can't make trouble.
We need two "scrub the list" loops because only one branch
should touch hardware and advance the schedule.

The urb_dequeue() method forgets to unlink 'struct musb_qh' from the
control or bulk schedules when the URB being cancelled is the only
one queued to its endpoint. That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.
Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback). Since a QH with an empty URB
list is now supposed to be freed, do that. And remove a now-useless
check from musb_advance_schedule().

Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:
- Use clk_enable()/clk_disable() ... the "always enable USB clocks"
code this originally relied on has since been removed.
- Initialize the USB device only after the relevant I2C GPIOs are
available, so the host side can properly enable VBUS.
- Tweak init sequencing to cope with mainline's relatively late init
of the I2C system bus for power switches, transceivers, and so on.
Sanity tested on DM6664 EVM for host and peripheral modes; that system

This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter. This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor! The
usb_get_string() routine needs to check whether it got the right
type of descriptor.
Oddly enough, this sort of check is already present in
usb_get_descriptor(). The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.

Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state. This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.
This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.
This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

Disable the SSB core on device shutdown.
This has two advantages:
1) A clean device shutdown is always desired here, because we disable
the device's global crystal in the next statement.
2) This fixes a bug where the device will come up with the enable-bit
set on the next initialization (without a reboot inbetween).
This causes breakage on the second initialization due to code that
checks this bit (ssb_device_is_enabled() checks).

With (some) Technisat cards you cannot run multiple DVB applications

There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.
This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.
This patch is urgently needed to support the rev 2.8 of the hardware and solves

With the mandatory algorithm testing at registration, we have
now created a deadlock with algorithms requiring fallbacks.
This can happen if the module containing the algorithm requiring
fallback is loaded first, without the fallback module being loaded
first. The system will then try to test the new algorithm, find
that it needs to load a fallback, and then try to load that.
As both algorithms share the same module alias, it can attempt
to load the original algorithm again and block indefinitely.
As algorithms requiring fallbacks are a special case, we can fix
this by giving them a different module alias than the rest. Then
it's just a matter of using the right aliases according to what
algorithms we're trying to find.

For some reason, sata_mv doesn't clear interrupt status during init
when it's running on an SoC host adapter. If the bootloader has
touched the SATA controller before starting Linux, Linux can end up
enabling the SATA interrupt with events pending, which will cause the

breaks all further accesses to the controller.

Found that resume fails (2.6.28) with "serial number mismatch 'some

That's because the controller firmware fills different serial number in
the IDENTIFY every boot.
The patch below fixes the resume simply clearing the serial number. The
proper fix would be probably to fill in the serial number of the RAID
volume instead. I assume that there must be something like that stored on

There has been a race in raid10 and raid1 for a long time
which has only recently started showing up due to a scheduler changed.
When a sync_read request finishes, as soon as reschedule_retry
is called, another thread can mark the resync request as having
completed, so md_do_sync can finish, ->stop can be called, and
->conf can be freed. So using conf after reschedule_retry is not
safe.
Similarly, when finishing a sync_write, calling md_done_sync must be
the last thing we do, as it allows a chain of events which will free
conf and other data structures.

For raid1/4/5/6, resync (fixing inconsistencies between devices) is
very similar to recovery (rebuilding a failed device onto a spare).
The both walk through the device addresses in order.
For raid10 it can be quite different. resync follows the 'array'
address, and makes sure all copies are the same. Recover walks
through 'device' addresses and recreates each missing block.
The 'bitmap_cond_end_sync' function allows the write-intent-bitmap
(When present) to be updated to reflect a partially completed resync.
It makes assumptions which mean that it does not work correctly for
raid10 recovery at all.
In particularly, it can cause bitmap-directed recovery of a raid10 to
not recovery some of the blocks that need to be recovered.
So move the call to bitmap_cond_end_sync into the resync path, rather
than being in the common "resync or recovery" path.

When doing recovery on a raid10 with a write-intent bitmap, we only
need to recovery chunks that are flagged in the bitmap.
However if we choose to skip a chunk as it isn't flag, the code
currently skips the whole raid10-chunk, thus it might not recovery
some blocks that need recovering.
This patch fixes it.
In case that is confusing, it might help to understand that there
is a 'raid10 chunk size' which guides how data is distributed across
the devices, and a 'bitmap chunk size' which says how much data
corresponds to a single bit in the bitmap.
This bug only affects cases where the bitmap chunk size is smaller
than the raid10 chunk size.

firedtv: dvb demux: remove a bogus loop
This loop is unnecessary because
- only active channel[].pid's will be sent to the device,
- when a channel is activated, its pid is set to dvbdmxfeed->pid.

covered by the fdtv->demux_mutex.

firedtv: register input device as child of a FireWire device
Instead of one virtual input device which exists for the whole lifetime
of the driver and receives events from all connected FireDTVs, register
one input device for each firedtv device. These input devices will show
up as children of the respective firedtv devices in the sysfs hierarchy.
However, the implementation falls short because of a bug in userspace:
Udev's path_id script gets stuck with 100% CPU utilization, maybe
because of an assumption about the maximum ieee1394 device hierarchy
depth.
To avoid this bug, we use the fw-host device instead of the proper
unit_directory device as parent of the input device.
There is hope that the port to the new firewire stack won't be inhibited
by this userspace bug because there are no fw-host devices there.

While Module_Vendor_ID in the configuration ROM's root directory is
mandatory, there often aren't vendor IDs in unit directories. This
affects the new firedtv driver which is meant to be auto-loaded and
matched only for vendor-specific devices.
We now always copy ne->vendor_id into ud->vendor_id before we scan a
unit directory (and fill in a possibly present vendor ID from there).
This way, the root directory's vendor ID is used as fallback in the
"uevent" environment for modprobe'ing per module alias when a node was
plugged in, and in the driver match routine when protocol drivers are
bound to unit directories. It will however not be used as sysfs
attribute of a unit directory device.

These will be used by the firedtv driver. Like hpsb_node_write() they
are much better APIs for high-level drivers than hpsb_write() and its
siblings --- easier to use correctly and also terser.
Unlike hspb_node_write(), the two new functions will only be used by
one call site. Hence make them static inline instead of exported
symbols.

A compiler barrier (explicit on the read side, implicit on the write
side) is not quite enough for what has to be accomplished here. Use
hardware memory barriers on systems which need them.
(Of course a full fix of generation handling would require much more
than this. The ieee1394 core's bus generation counter had to be tied to
the controller's bus generation counter; cf. Kristian's stack. It's
just that I have other current business with the code around these
barrier()s, so why not do at least this small fix.)

non-functional anyway at the moment. This should be fixed eventually,
probably by turning the tasklet into a worqueue job.
Convert everything else from semaphore to mutex.
