I was trying to backport the following commit to RHEL-6

    Subject: [PATCH] btusb: add device entry for Broadcom SoftSailing

and noticed it wasn't working on an HP Elitebook.  Looking into the patch I
noticed a very subtle typo in the ids.  The patch has '0x05ac' instead of
'0x0a5c'.  A snippet of the lsusb -v output also shows this:

Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp.
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass          255 Vendor Specific Class
  bDeviceSubClass         1
  bDeviceProtocol         1
  bMaxPacketSize0        64
  idVendor           0x0a5c Broadcom Corp.
  idProduct          0x21e1
  bcdDevice            1.12
  iManufacturer           1 Broadcom Corp
  iProduct                2 BCM20702A0
  iSerial                 3 60D819F0338C
  bNumConfigurations      1

Looking at other Broadcom ids, the fix matches them whereas the original patch
matches Apple's ids.

Tested on an HP Elitebook 8760w.  The btusb binds and the userspace stuff loads
correctly.

Johan Hovold 33b69bf80a Bluetooth: hci_ldisc: fix NULL-pointer dereference on tty_close
Do not close protocol driver until device has been unregistered.

This fixes a race between tty_close and hci_dev_open which can result in
a NULL-pointer dereference.

The line discipline closes the protocol driver while we may still have
hci_dev_open sleeping on the req_lock mutex resulting in a NULL-pointer
dereference when lock is acquired and hci_init_req called.

Bug is 100% reproducible using hciattach and a disconnected serial port:

0. # hciattach -n ttyO1 any noflow

1. hci_dev_open called from hci_power_on grabs req lock
2. hci_init_req executes but device fails to initialise (times out
   eventually)
3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock
4. hci_uart_tty_close detaches protocol driver and cancels init req
5. hci_dev_open (1) releases req lock
6. hci_dev_open (3) grabs req lock, calls hci_init_req, which triggers oops
   when request is prepared in hci_uart_send_frame

After unregistering an hci_dev object a bluetooth driver does not have
any callbacks in the hci_dev structure left over. Therefore, there is no
need to keep a reference to the module.

Previously, we needed this to protect the hci-destruct callback.
However, this callback is no longer available so we do not need this
owner field, anymore.  Drivers now call hci_unregister_dev() and they
are done with the object.

We currently leak the hci_uart object if HCI_UART_PROTO_SET is never set
because the hci-destruct callback will then never be called.  This fix
removes the hci-destruct callback and frees the driver internal private
hci_uart object directly on tty-close. We call hci_unregister_dev() here
so the hci-core will never call our callbacks again (except destruct).
Therefore, we can safely free the driver internal data right away and
set the destruct callback to NULL.

This frees the private driver data on USB shutdown instead of using the
hci-destruct callback. We already call usb_set_intfdata(intf, NULL) but
we do not do the same with the hci object. This would be totally safe,
though.

After calling hci_unregister_dev()/hci_free_dev() the hdev object will
never call any callback of us again except the destruct callback.
Therefore, we can safely set the destruct callback to NULL and free the
driver data right away.  This allows to unload the module without
waiting for the hdev device to be released.

David Herrmann bf18c7118c Bluetooth: vhci: Free driver_data on file release
This removes the hci-destruct callback and instead frees the private
driver data in the vhci_release file release function. There is no
reason to keep private driver data available if the driver has already
shut down.

After vhci_release is called our module can be unloaded. The only reason
it is kept alive is the hci-core having a module-ref on us because of
our destruct callback. However, this callback only frees
hdev->driver_data. That is, we wait for the hdev-device to get destroyed
to free our internal driver-data. In fact, the hci-core does never touch
hdev->driver_data so it doesn't care if it is NULL. Therefore, we simply
free it when unloading the driver.

Another important fact is that the hdev core does not call any callbacks
other than the destruct-cb after hci_unregister_dev() has been called.
So there is no function of our module that will be called nor does the
hci-core touch hdev->driver_data. Hence, no other code can touch
hdev->driver_data after our cleanup so the destruct callback is
definitely unnecessary here.

Greg Kroah-Hartman ff4b8a57f0 Merge branch 'driver-core-next' into Linux 3.2
This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.

The microcode_core.c patch was provided by Stephen Rothwell
<sfr@canb.auug.org.au> who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

Tejun Heo 3a7cbd50f7 freezer: don't unnecessarily set PF_NOFREEZE explicitly
Some drivers set PF_NOFREEZE in their kthread functions which is
completely unnecessary and racy - some part of freezer code doesn't
consider cases where PF_NOFREEZE is set asynchronous to freezer
operations.

In general, there's no reason to allow setting PF_NOFREEZE explicitly.
Remove them and change the documentation to note that setting
PF_NOFREEZE directly isn't allowed.

-v2: Dropped change to twl4030-irq.c as it no longer uses PF_NOFREEZE.

When loading the usb-configuration we do not signal the end of configuration on

This also replaces GFP_ATOMIC with GFP_KERNEL as we are allowed to sleep here.

"device got disconnected" aren't things to worry about).

Paul Bolle 5a9b80e2cd Bluetooth: btusb: also be quiet when suspending
usb_submit_urb() returns -ENODEV when a usb device is disconnected. In
commit 4935f1c164 ("Bluetooth: btusb: be
quiet on device disconnect") I stopped treating that return as an error
in the three btusb_*_complete() functions.

It turns out btusb_send_frame() generates a similar error if the system
is suspended while the bluetooth usb device is enabled. The sensible
thing to do here seems to be to treat -ENODEV (and -EPERM) just like the
btusb_*_complete() functions now do.

Peter Hurley 9fd481e03c Bluetooth: Allow ACL packets over USB in HCI_RAW mode
Removed tests which prevent transmission of ACL packets
when the device is in HCI_RAW mode. These tests verified that
there are ACL or LE links currently tracked by the HCI
connection manager. However, a HCI_RAW mode device does not
use the connection manager. In these circumstances, the connection
counts will be zero, and thus, transmitted ACL packets dropped.

The acl_num test is actually a vestige of a previous bulk URB
scheme that is no longer used by this driver (bulk URBs were not
started until at least one ACL connection was created). This was
incompatible with some endpoint implementations and was dropped -
see commit 43c2e57f94.

The utility of these tests is marginal - currently, the hci tx
scheduler cannot send an ACL or LE packet for an untracked connection
(except if the device is in HCI_RAW mode).

Lastly, no other transport layer driver enforces these same tests.

Reordered the BT ST channel registration, to make sure that the

situation where incoming events may cause kernel panic in the ST
driver if the event channel is not yet registered to handle
incoming events.In addition, the deregistration of the channels
was also modified, to be in the reversed order of the registration,
to allow the event channel to be the last one unregistered.

Paul Bolle 4935f1c164 Bluetooth: btusb: be quiet on device disconnect
Disabling the bluetooth usb device embedded in (some) ThinkPads tends to
lead to errors like these:
    btusb_bulk_complete: hci0 urb ffff88011b9bfd68 failed to resubmit (19)
    btusb_intr_complete: hci0 urb ffff88011b46a318 failed to resubmit (19)
    btusb_bulk_complete: hci0 urb ffff88011b46a000 failed to resubmit (19)

That is because usb_disconnect() doesn't "quiesces" pending urbs.

Disconnecting a device is a normal thing to happen so it's no big deal
that usb_submit_urb() returns -ENODEV. The simplest way to get rid of
these errors is to stop treating that return as an error. Trivial,
actually.

While we're at it, add comments to be explicit about the reasons we're
not complaining about -EPERM and -ENODEV.

Linus Torvalds 55db4c64ed Revert "tty: make receive_buf() return the amout of bytes received"
This reverts commit b1c43f82c5.

It was broken in so many ways, and results in random odd pty issues.

It re-introduced the buggy schedule_work() in flush_to_ldisc() that can
cause endless work-loops (see commit a5660b41af6a: "tty: fix endless
work loop when the buffer fills up").

It also used an "unsigned int" return value fo the ->receive_buf()
function, but then made multiple functions return a negative error code,
and didn't actually check for the error in the caller.

And it didn't actually work at all.  BenH bisected down odd tty behavior
to it:
  "It looks like the patch is causing some major malfunctions of the X
   server for me, possibly related to PTYs.  For example, cat'ing a
   large file in a gnome terminal hangs the kernel for -minutes- in a
   loop of what looks like flush_to_ldisc/workqueue code, (some ftrace
   data in the quoted bits further down).

   ...

   Some more data: It -looks- like what happens is that the
   flush_to_ldisc work queue entry constantly re-queues itself (because
   the PTY is full ?) and the workqueue thread will basically loop
   forver calling it without ever scheduling, thus starving the consumer
   process that could have emptied the PTY."

which is pretty much exactly the problem we fixed in a5660b41af.

Milton Miller pointed out the 'unsigned int' issue.

an Bluetooth Intermec scanner) to just stop responding after a while
with messages like

  [ 4533.361959] btusb 8-1:1.0: no reset_resume for driver btusb?

Pavan Savoy 363907af85 Bluetooth: btwilink driver
This is the bluetooth protocol driver for the TI WiLink7 chipsets.
Texas Instrument's WiLink chipsets combine wireless technologies
like BT, FM, GPS and WLAN onto a single chip.

This Bluetooth driver works on top of the TI_ST shared transport
line discipline driver which also allows other drivers like
FM V4L2 and GPS character driver to make use of the same UART interface.

Kconfig and Makefile modifications to enable the Bluetooth
driver for Texas Instrument's WiLink 7 chipset.

Rogério Brito 84f0e17f78 Bluetooth: ath3k: Avoid duplication of code
In commit 86e09287e4, to reduce memory
usage, the functions of the ath3k module were rewritten to release the
firmware blob after it has been loaded (successfully or not).

The resuting code has some redundancy and the compiler can potentially
produce better code if we omit a function call that is unconditionally
executed in

,----
|     if (ath3k_load_firmware(udev, firmware)) {
|             release_firmware(firmware);
|             return -EIO;
|     }
|     release_firmware(firmware);
|
|     return 0;
| }
`----

It may also be argued that the rewritten code becomes easier to read,
and also to see the code coverage of the snippet in question.

Arnd Bergmann 6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

===== begin semantic patch =====
// This adds an llseek= method to all file operations,
// as a preparation for making no_llseek the default.
//
// The rules are
// - use no_llseek explicitly if we do nonseekable_open
// - use seq_lseek for sequential files
// - use default_llseek if we know we access f_pos
// - use noop_llseek if we know we don't access f_pos,
//   but we still want to allow users to call lseek

fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
accordinly. Drivers wishing to override certain settings may do so in
the callback function, but they no longer need to parse the CIS entries
stored in cistpl_cftable_entry_t themselves.

IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
(all other drivers). As this flags seems to relate to ioport access, make
it conditional to the driver having requested IO port access. There are two
drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

Amitkumar Karwar d1d10d7830 Bluetooth: Process interrupt in main thread of btmrvl driver as well
When driver is sending a command or data and the firmware is also
sending a sleep event, sometimes it is observed that driver will
continue to send the command/data to firmware right after processing
sleep event. Once sleep event is processed driver is not supposed to
send anything because firmware is in sleep state after that. Previously
interrupt processing was done in SDIO interrupt callback handler.
Now it is done in btmrvl driver main thread to solve the
cross-sending properly.

Dominik Brodowski 317b6d6300 pcmcia: dev_node removal (write-only drivers)
dev_node_t was only used to transport some minor/major numbers
from the PCMCIA device drivers to deprecated userspace helpers.
However, only a few drivers made use of it, and the userspace
helpers are deprecated anyways. Therefore, get rid of dev_node_t .

As a first step, remove any usage of dev_node_t from drivers which
only wrote to this typedef/struct, but did not make use of it.

Dominik Brodowski eb14120f74 pcmcia: re-work pcmcia_request_irq()
Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:

- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.

- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
  clean up automatically on calls to pcmcia_disable_device() or
  device ejection.

- drivers still not capable of IRQF_SHARED (or not telling us so) may
  use the deprecated pcmcia_request_exclusive_irq() for the time
  being; they might receive a shared IRQ nonetheless.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Dominik Brodowski 5fa9167a1b pcmcia: rework the irq_req_t typedef
Most of the irq_req_t typedef'd struct can be re-worked quite
easily:

(1) IRQInfo2 was unused in any case, so drop it.

(2) IRQInfo1 was used write-only, so drop it.

(3) Instance (private data to be passed to the IRQ handler):
	Most PCMCIA drivers using pcmcia_request_irq() to actually
	register an IRQ handler set the "dev_id" to the same pointer
	as the "priv" pointer in struct pcmcia_device. Modify the two
	exceptions (ipwireless, ibmtr_cs) to also work this waym and
	set the IRQ handler's "dev_id" to p_dev->priv unconditionally.

(4) Handler is to be of type irq_handler_t.

(5) Handler != NULL already tells whether an IRQ handler is present.
	Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
	irq_req_t.Attributes.

Linus Torvalds 404291ac9e btusb bluetooth driver: wait for 'waker' work too before closing
Rafael debugged a resume-time hang (with oopses in workqueue handling)
on his laptop that was due to the 'waker' workqueue entry being
disconnected and then released without the workqueue entry having been
synchronized.

Several people were involved, with Oleg Nesterov doing a debugging patch
showing what workqueue entry was corrupt etc.

This was a regression introduced by commit 7bee549e19 ("Bluetooth: Add
USB autosuspend support to btusb driver") as Rafael points out (not
actually bisected, but it became clear once the bug was found).

Oliver Neukum 7bee549e19 Bluetooth: Add USB autosuspend support to btusb driver
This patch adds support of USB autosuspend to the btusb driver.

If the device doesn't support remote wakeup, simple support based on
up/down is provided. If the device supports remote wakeup, additional
support for autosuspend while the interface is up is provided. This is
done by queueing URBs in an anchor structure and waking the device up
from a work queue on sending. Reception triggers remote wakeup.

The last busy facility of the USB autosuspend code is used. To close
a race between autosuspend and transmission, a counter of ongoing
transmissions is maintained.

Add #ifdefs for CONFIG_PM as necessary.

Alan Cox c65c9bc3ef tty: rewrite the ldisc locking
There are several pretty much unfixable races in the old ldisc code, especially
with respect to pty behaviour and also to hangup. It's easier to rewrite the
code than simply try and patch it up.

This patch
- splits the ldisc from the tty (so we will be able to refcount it more cleanly
  later)
- introduces a mutex lock for ldisc changing on an active device
- fixes the complete mess that hangup caused
- implements hopefully correct setldisc/close/hangup locking

There are still some problems around pty pairs that have always been there but
at least it is now possible to understand the code and fix further problems.

This fixes the following known bugs
- hang up can leak ldisc references
- hang up may not call open/close on ldisc in a matched way
- pty/tty pairs can deadlock during an ldisc change
- reading the ldisc proc files can cause every ldisc to be loaded

and probably a few other of the mysterious ldisc race reports.

I'm sure it also adds the odd new one.

Marcel Holtmann 7a9d402053 Bluetooth: Send HCI Reset command by default on device initialization
The Bluetooth subsystem was not using the HCI Reset command when doing
device initialization. The Bluetooth 1.0b specification was ambiguous
on how the device firmware was suppose to handle it. Almost every device
was triggering a transport reset at the same time. In case of USB this
ended up in disconnects from the bus.

All modern Bluetooth dongles handle this perfectly fine and a lot of
them actually require that HCI Reset is sent. If not then they are
either stuck in their HID Proxy mode or their internal structures for
inquiry and paging are not correctly setup.

To handle old and new devices smoothly the Bluetooth subsystem contains
a quirk to force the HCI Reset on initialization. However maintaining
such a quirk becomes more and more complicated. This patch turns the
logic around and lets the old devices disable the HCI Reset command.

The only device where the HCI_QUIRK_NO_RESET is still needed are the
original Digianswer devices and dongles with an early CSR firmware.

CSR reported that they fixed this for version 12 firmware. The last
official release of version 11 firmware is build ID 115. The first
version 12 candidate was build ID 117.

The btusb driver contains two typos that result in some buggy behavior,

During initialization the submitting of interrupt URBs might fail and
then make sure to remove the correct flag and not one of the hci_dev
flags.

When closing down the interface make sure to kill the anchor for the
ISOC URBs and not kill the interrupt URBs twice.

Also cancel any scheduled work when closing down the interface.

David Newall 3611f4d2a5 hci_ldisc: fix null pointer deref
Arjan:

  With the help of kerneloops.org I've spotted a nice little interaction
  between the TTY layer and the bluetooth code, however the tty layer is not
  something I'm all too familiar with so I rather ask than brute-force fix the
  code incorrectly.

  The raw details are at:
  http://www.kerneloops.org/search.php?search=uart_flush_buffer

  What happens is that, on closing the bluetooth tty, the tty layer goes
  into the release_dev() function, which first does a bunch of stuff, then
  sets the file->private_data to NULL, does some more stuff and then calls the
  ldisc close function.  Which in this case, is hci_uart_tty_close().

  Now, hci_uart_tty_close() calls hci_uart_close() which clears some
  internal bit, and then calls hci_uart_flush()...  which calls back to the
  tty layers' uart_flush_buffer() function.  (in drivers/bluetooth/hci_tty.c
  around line 194) Which then WARN_ON()'s because that's not allowed/supposed
  to be called this late in the shutdown of the port....

  Should the bluetooth driver even call this flush function at all??

David:

  This seems to be what happens: Hci_uart_close() flushes using
  hci_uart_flush().  Subsequently, in hci_dev_do_close(), (one step in
  hci_unregister_dev()), hci_uart_flush() is called again.  The comment in
  uart_flush_buffer(), relating to the WARN_ON(), indicates you can't flush
  after the port is closed; which sounds reasonable.  I think hci_uart_close()
  should set hdev->flush to NULL before returning.  Hci_dev_do_close() does
  check for this.  The code path is rather involved and I'm not entirely clear
  of all steps, but I think that's what should be done.
