4f62f6cb93 [Bluetooth] Add reset quirk for new Targus and Belkin dongles
Targus and Belkin have come out with new Bluetooth 2.1 capable dongles
using the latest BCM2046 chip from Broadcom. Both of them are so called
HID proxy dongles and they need to send HCI_Reset before they become
fully operational.

36010ff678 [Bluetooth] Fix double frees on error paths of btusb and bpa10x drivers
The transfer buffer of an URB will be automatically freed when using
the URB_FREE_BUFFER transfer_flag. So the extra calls to kfree() will
cause a double free.

5fbcd260c2 [Bluetooth] Fix USB disconnect handling of btusb driver
The USB transport specification for Bluetooth splits the ACL and SCO
handling into two separate interfaces. In Linux it possible to probe
and disconnect these interfaces independently. So make sure that both
interfaces are tightly bound together.

This fixes the suspend regression that some people have expierenced.

e8c3c3d22b [Bluetooth] Fix wrong URB handling of btusb driver
The btusb driver contains two typos that result in some buggy behavior,
but the impact is not immediately visible.

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.

9bfa35fe42 [Bluetooth] Add SCO support to btusb driver
The new generic driver for Bluetooth USB devices was missing proper
SCO support. The driver now claims the second interface for these USB
devices to allow the flow of SCO packets. It also handles switching
of the alternate setting and re-submission of isochronous URBs.

The btusb driver is now a full replacement for hci_usb and thus the
experimental tag has been removed and this driver is promoted as
preferred one.

Move the line disciplines towards a conventional ->ops arrangement.  For
the moment the actual 'tty_ldisc' struct in the tty is kept as part of

all settles down we want to refcount ldiscs separately to the tty.

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.

a9de924806 [Bluetooth] Switch from OGF+OCF to using only opcodes
The Bluetooth HCI commands are divided into logical OGF groups for
easier identification of their purposes. While this still makes sense
for the written specification, its makes the code only more complex
and harder to read. So instead of using separate OGF and OCF values
to identify the commands, use a common 16-bit opcode that combines
both values. As a side effect this also reduces the complexity of
OGF and OCF calculations during command header parsing.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

e2d4096365 [PATCH] pcmcia: use bitfield instead of p_state and state
Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the
attachement _and_ configuration was successful.

15b99ac172 [PATCH] pcmcia: add return value to _config() functions
Most of the driver initialization isn't done in the .probe function, but in
the internal _config() functions. Make them return a value, so that .probe
can properly report whether the probing of the device succeeded or not.

fba395eee7 [PATCH] pcmcia: remove dev_link_t and client_handle_t indirection
dev_link_t * and client_handle_t both mean struct pcmcai_device * by now.
Therefore, remove all such indirections.

fd238232cd [PATCH] pcmcia: embed dev_link_t into struct pcmcia_device
Embed dev_link_t into struct pcmcia_device(), as they basically address the
same entity. The actual contents of dev_link_t will be cleaned up step by step.
This patch includes a bugfix from and signed-off-by Andrew Morton.

70294b4683 [PATCH] pcmcia: remove unneeded Vcc pseudo setting
As we do not allow setting Vcc in the pcmcia core, and Vpp1 and
Vpp2 can only be set to the same value, a lot of code can be
streamlined.

8661bb5b4a [PATCH] pcmcia: default suspend and resume handling
In all but one case, the suspend and resume functions of PCMCIA drivers
contain mostly of calls to pcmcia_release_configuration() and
pcmcia_request_configuration(). Therefore, move this code out of the
drivers and into the core.

5f2a71fcb7 [PATCH] pcmcia: add pcmcia_disable_device
pcmcia_disable_device(struct pcmcia_device *p_dev) performs the necessary
cleanups upon device or driver removal: it calls the appropriate
pcmcia_release_* functions, and can replace (most) of the current drivers'
_release() functions.

9225806386 [Bluetooth] Fix firmware loading problem of BT3C driver
Before the PCMCIA subsystem was fully integrated into the device and
driver model, the BT3C driver had to workaround this when loading the
firmware. This workaround is broken and makes the driver oops when
loading the firmware. This patch removes this workaround and uses now
the provided device structure from the PCMCIA subsystem.
