Andrew Morton a5176b7897 [PATCH] USB: Nokia E70 is an unusual device
Taken from http://bugzilla.kernel.org/show_bug.cgi?id=7508

When the Nokia E70 Phone is plugged in to the USB port, I get:

end_request: I/O error, dev sda, sector 1824527
sd 0:0:0:0: SCSI error: return code = 0x10070000
end_request: I/O error, dev sda, sector 1824535
sd 0:0:0:0: SCSI error: return code = 0x10070000

The fix is to add these lines to drivers/usb/storage/unusual_devs.h:

Chris Frey df251b8bfc USB: fix to usbfs_snoop logging of user defined control urbs
When sending CONTROL URB's using the usual CONTROL ioctl, logging works
fine, but when sending them via SUBMITURB, like VMWare does, the
control fields are not logged.  This patch fixes that.

I didn't see any major changes to devio.c recently, so this patch should apply
cleanly to even the latest kernel.  I can resubmit if it doesn't.

Tony Olech 4b87361d49 USB: u132-hcd/ftdi-elan: add support for Option GT 3G Quad card
ELAN's U132 is a USB to CardBus OHCI controller adapter,
    designed specifically for CardBus 3G data cards to
    function in machines without a CardBus slot.
The "ftdi-elan" module is a USB client driver, that detects
    a supported CardBus OHCI controller plugged into the
    U132 adapter and thereafter provides the conduit for
    for access by the "u132-hcd" module.
The "u132-hcd" module is a (cut-down OHCI) host controller
    that supports a single OHCI function of the CardBus 
    card inserted into the U132 adapter.

The problem with the initial implementation is that when
the CardBus card inserted into the U132 adapter has multiple
functions (and a CardBus card can support up to 4 functions),
it was the first function that was arbitrarily choosen.

The first batch of 3G cards tested, like the Merlin Qualcomm
V620, have two functions each supporting a seperate USB OHCI
host controller, of which it was that first function that is
wired up to the 3G modem.

Then along comes the Vodafone Mobile Connect 3G/GPRS data card,
aka "Option GT 3G Quad" as printed on it's rear or "Option N.V.
GlobeTrotter Fusion Quad Lite" as read with "lspci -v". And it
has the meaningful functionality in the second CardBus function.

That presents a problem because it was the "ftdi-elan" module
alone that knows how to communicate to the embedded CardBus slot
and the "u132-hcd" module alone that knows how to access the
pcmcia configuration and CardBus accessible memory space. And
of course, the information about attached (internally hardwired)
devices is contained within USB configuration embedded somewhere
within the CardBus card.

If only the "u132-hcd" module probe() interface could return a
result code that propagated back to the instigating function
platform_device_register() then the "ftdi-elan" module could
try an alternative CardBus function.     However in spite of
the recent changes to the drivers/base/ routines that moved 
device_attach() from bus_add_device() to bus_attach_device()
both of those routines lose the "failed to attach" 0 result
code and thus the calling routine, namely device_add() is
incapable of propaging the "failed to attach" condition back
to platform_device_add() and consequently back to the caller
of platform_device_register()

Experiments show that patching bus_attach_device() to return
ENODEV fails with the kernel locking up very early during
boot. But, however, if the patch is restricted to calls from
platform_device_add() then it does seem to work.

Unfortunately, until the kernel's drivers/base is properly
modified to propagate -ENODEV back to the caller of
platform_device_register(), it is necessary to "fix" the
"ftdi-elan" module by importing knowledge from the 
"u132-hcd" module. This is the reason for the duplicated
functionality introduced in this patch.

This is an update to the AT91 USB Device (Gadget) driver.

The base I/O address provided in the platform_device resources is now
ioremap()'ed instead of using a statically mapped memory area.  This
helps portability to the newer AT91sam926x processors.

The major change is that we now have to pass a 'struct at91_udc'
parameter to at91_udp_read() and at91_udp_write().

Takamasa Ohtake 23d10a9e37 USB: ohci handles hardware faults during root port resets
I have found a problem where the root_port_reset() goes into an infinite
loop and stalls the kernel.

This happens when a hardware fault inside the machine occurs during a small
timing window.  In case of USB device connection, if a USB device responds to
hcd_submit_urb(), and later the controller fails before root_port_reset(),
root_port_reset() will loop infinitely because ohci_readl() will always
return "-1".  Such a failure can include ejecting a CardBus OHCI controller.

The probability of this problem is low, but it will increase if PnP type
usage is frequent.  The attached patch can solve this problem and I believe
that it is better to fix this problem.

Similarly, provide consistent/simpler handling for a should-not-happen

driver is still loaded.  Such code dates back to early versions of the
first implementation of the gadget API, and has never been triggered.

Includes relevant section annotation fixs for gmidi.c, file_storage.c,

Alan Stern 5f8364b7d6 UHCI: module parameter to ignore overcurrent changes
Certain boards seem to like to issue false overcurrent notifications,
for example on ports that don't have anything connected to them.  This
looks like a hardware error, at the level of noise to those ports'
overcurrent input signals (or non-debounced VBUS comparators).  This
surfaces to users as truly massive amounts of syslog spam from khubd
(which is appropriate for real hardware problems, except for the
volume from multiple ports).

Using this new "ignore_oc" flag helps such systems work more sanely,
by preventing such indications from getting to khubd (and spamming
syslog).  The downside is of course that true overcurrent errors will
be masked; they'll appear as spontaneous disconnects, without the
diagnostics that will let users troubleshoot issues like
short-circuited cables.  In addition, controllers with no devices
attached will be forced to poll for new devices rather than relying on
interrupts, since each overcurrent event would generate a new
interrupt.

This patch (as826) is essentially a copy of David Brownell's ignore_oc
patch for ehci-hcd, ported to uhci-hcd.

Jeff Garzik abc9404bb0 USB: fix ohci.h over-use warnings
When u132-hcd is built, it includes local header ohci.h, which appears
to have been intended only for use by ohci-hcd.

This throws warnings about functions which are defined and not used.
The warnings thrown are because three small functions are implemented in
the header, but not declared 'inline', a rather strange affair.

Since these functions are small, let's go ahead and define them as
'inline', just like the inline functions surrounding them.  This makes
things more consistent, and kills the warnings.

This patch is for 2.6.17 or later kernels.

When "hwinfo --modem" is executed it opens the funsoft USB serial device and
disables canonical mode.  The device is kept this way until hwininfo has
finished probing any modems on a system.  The funsoft device expects to be

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current

Alan Stern 94fcda1f8a usbcore: remove unused argument in autosuspend
Thanks to several earlier patches, usb_autosuspend_device() and
usb_autoresume_device() are never called with a second argument other
than 1.  This patch (as819) removes the now-redundant argument.

It also consolidates some common code between those two routines,
putting it into a new subroutine called usb_autopm_do_device().  And
it includes a sizable kerneldoc update for the affected functions.

Alan Stern ee49fb5dc8 USB: keep count of unsuspended children
This patch (as818b) simplifies autosuspend processing by keeping track
of the number of unsuspended children of each USB hub.  This will
permit us to avoid a good deal of unnecessary work all the time; we
will no longer have to create a bunch of workqueue entries to carry
out autosuspend requests, only to have them fail because one of the
hub's children isn't suspended.

The basic idea is simple.  There already is a usage counter in the
usb_device structure for preventing autosuspends.  The patch just
increments that counter for every unsuspended child.  There's only one
tricky part: When a device disconnects we need to remember whether it
was suspended at the time (leave the counter alone) or not (decrement
the counter).

Alan Stern d25450c687 USB hub: simplify remote-wakeup handling
This patch (as817) simplifies the remote-wakeup processing in the hub
driver.  Now instead of using a specialized code path, it relies on
the standard USB resume routines.  The hub_port_resume() function does
an initial get_port_status() to see whether the port has already
resumed itself (as it does when a remote-wakeup request is sent).
This will slow down handling of other resume events slightly, but not
enough to matter.

The patch also changes the hub_port_status() routine, making it return
an error if a short reply is received.

Alan Stern 1f9fc882d9 OHCI: make autostop conditional on CONFIG_PM
Unlike UHCI, OHCI does not exert any DMA load on the system when no
devices are connected.  Consequently there is no advantage to doing
an autostop other than the power savings, so we shouldn't compile the
necessary code unless CONFIG_PM is enabled.

This patch (as820) makes the root-hub suspend and resume routines
conditional on CONFIG_PM.  It also prevents autostop from activating
if the device_may_wakeup flag isn't set; some people use this flag to
alert the driver about Resume-Detect bugs in the hardware.

Alan Stern 8c03356a55 EHCI: Fix root-hub and port suspend/resume problems
This patch (as738b) fixes numerous problems in the controller/root-hub
suspend/resume/remote-wakeup support in ehci-hcd:

	The bus_resume() routine should wake up only the ports that
	were suspended by bus_suspend().  Ports that were already
	suspended should remain that way.

	The interrupt mask is used to detect loss of power in the
	bus_resume() routine (if the mask is 0 then power was lost).
	However bus_suspend() always sets the mask to 0.  Instead the
	mask should retain its normal value, with port-change-detect
	interrupts disabled if remote wakeup is turned off.

	The interrupt mask should be reset to its correct value at the
	end of bus_resume() regardless of whether power was lost.

	bus_resume() reinitializes the operational registers if power
	was lost.  However those registers are not in the aux power
	well, hence they can lose their values whenever the controller
	is put into D3.  They should always be reinitialized.

	When a port-change interrupt occurs and the root hub is
	suspended, the interrupt handler should request a root-hub
	resume instead of starting up the controller all by itself.

	There's no need for the interrupt handler to request a
	root-hub resume every time a suspended port sends a
	remote-wakeup request.

	The pci_resume() method doesn't need to check for connected
	ports when deciding whether or not to reset the controller.
	It can make that decision based on whether Vaux power was
	maintained.

	Even when the controller does not need to be reset,
	pci_resume() must undo the effect of pci_suspend() by
	re-enabling the interrupt mask.

	If power was lost, pci_resume() must not call ehci_run().
	At this point the root hub is still supposed to be suspended,
	not running.  It's enough to rewrite the command register and
	set the configured_flag.

Adrian Bunk 9ce8540c88 USB: ftdi-elan.c: fixes and cleanups
This patch contains the following possible cleanups:
- make the needlessly global ftdi_release_platform_dev() static
- remove the unused usb_ftdi_elan_read_reg()
- proper prototypes for the following functions:
  - usb_ftdi_elan_read_pcimem()
  - usb_ftdi_elan_write_pcimem()

Note that the misplaced prototypes for the latter ones in
drivers/usb/host/u132-hcd.c were buggy. Depending on the calling
convention of the architecture calling one of them could have turned
your stack into garbage.

David Brownell 93f1a47c4a USB: add ehci_hcd.ignore_oc parameter
Certain boards seem to like to issue false overcurrent notifications, for
example on ports that don't have anything connected to them.  This looks
like a hardware error, at the level of noise to those ports' overcurrent
input signals (or non-debounced VBUS comparators).  This surfaces to users
as truly massive amounts of syslog spam from khubd (which is appropriate
for real hardware problems, except for the volume from multiple ports).

Using this new "ignore_oc" flag helps such systems work more sanely, by
preventing such indications from getting to khubd (and spam syslog).  The
downside is of course that true overcurrent errors will be masked; they'll
appear as spontaneous disconnects, without the diagnostics that will let
users troubleshoot issues like short circuited cables.

Note that the bulk of these reports seem to be with VIA southbridges, but
I think some were with Intel ones.

EHCI hooks for high speed electrical tests of the root hub ports.

The expectation is that a usermode program actually triggers the test,
making the same control request it would make for an external hub.
Tests for peripheral upstream ports would issue a different request.
In all cases, the hardware needs re-initialization before it could
be used "normally" again (e.g. unplug/replug, rmmod/modprobe).

Alan Stern 1f26e28d3e USB: net2280: don't send unwanted zero-length packets
The net2280 driver is too eager to send zero-length packets when
IN tokens are received on ep0.  No such packet should be sent (the
driver should NAK) before the gadget driver has queued the proper
response.  Otherwise deferred responses are impossible.

This patch (as823) makes net2280 avoid sending ZLPs for IN transfers
on ep0 until a response has been submitted, and avoids stalling when an
OUT packet is received before a request has been submitted for an OUT
transfer on ep0.

Hi everyone,
Sorry for the long time response but here is the patch, I think this way should
work, if anyone has any suggestion let me know. What I do now is, in case I
don't have the tty available I reschedule the work, I have tried it and it
works with no problem, I even tried removing the device, and didn't find
anything strange.

Luiz Fernando N. Capitulino 0c1ac4f25f USB: makes usb_endpoint_* functions inline.
We have no benefits of having the usb_endpoint_* functions as functions,
but making them inline saves text and data segment sizes:

text	   data	    bss	    dec	    hex	filename
14893634	3108770	1108840	19111244	1239d4c	vmlinux.func
14893185	3108566	1108840	19110591	1239abf	vmlinux.inline

 This is the result of a 2.6.19-rc3 kernel compiled with GCC 4.1.1 without
CONFIG_MODULES, CONFIG_CC_OPTIMIZE_FOR_SIZE, CONFIG_REGPARM options set.
USB support is fully enabled (while most of the other drivers are not),
and that kernel has most of the USB code ported to use the endpoint
functions.

That happens because a call to those functions are expensive (in terms
of bytes), while the function's size is smaller or have the same 'size' of
the call.

Alan Stern 93c8bf45e0 USB core: don't match interface descriptors for vendor-specific devices
This patch (as804) makes USB driver matching ignore the interface
class, subclass, and protocol if the device class is Vendor Specific.
Drivers can override this policy by specifying a Vendor ID as part
of the match; then vendor-specific matches are allowed.

Linus Walleij has reported a problem this patch fixes.  When a
particular mass-storage device is switched from mass-storage mode to
Media Transfer Protocol, the interface class remains set to mass-storage
and usb-storage binds to it erroneously, even though the device class
changes to Vendor-Specific.

This may cause a problem for some drivers until their match records can
be updated to include Vendor IDs.  But if it does, then those records
were broken to begin with.

inaky@linux.intel.com 88fafff9d7 usb hub: fix root hub code so it takes more than 15 devices per root hub
Wireless USB Host Controllers accept a large number of devices per
host, which shows up as a large number of ports in its root hub.

When the number of ports in a hub device goes over 16, the activation
of the hub fails with the cryptic message in klogd.

hub 2-0:1.0: activate --> -22

Following this further, it was seen that:

hub_probe()
  hub_configure()
    generates pipe number

    pseudo allocates buffer 'maxp' bytes in size using usb_maxpacket()

      The endpoint descriptor for a root hub interrupt endpoint is
      declared in
      drivers/usb/core/hcd.c:hs_rh_config_descriptor and declares it
      to be size two (supporting 15 devices max).

    hub_activate()
      usb_hcd_submit_urb()
        rh_urb_enqueue()
          urb->pipe is neither int nor ctl, so it errors out
            rh_queue_status()
              Returns -EINVAL because the buffer length is smaller
              than the minimum needed to report all the hub port
              bits as in accordance with USB2.0[11.12.3]. There has
              to be trunc((PORTS + 1 + 7) / 8) bytes of space at
              least.

Alan Stern confirmed that the reason for reading maxpktsize and not
the right amount is because some hubs are known to return more data
and thus cause overflow. 

So this patch simply changes the code to make the interrupt endpoint's
max packet size be at least the minimum required by USB_MAXCHILDREN
(instead of a fixed magic number) and add documentation for that. This
way we are always ahead of the limit.

inaky@linux.intel.com 4370525167 usb/hub: allow hubs up to 31 children
Current Wireless USB host hardware (Intel i1480 for example) allows up
to 22 devices to connect, thus bringing up the max number of children
in the WUSB Host Controller to 22 'fake' ports. Upcoming hardware
might raise that limit.

Makes almost no difference to go to 31, as the bit arrays are
byte-aligned (plus an extra bit in general), so 22 bits fit in 4 bytes
as 31 do.

As well, the only other array that depends on USB_MAXCHILDREN is
'struct usb_hub->indicator'. By declaring it 'u8' instead of 'enum
hub_led_mode', we reduce the size of each entry from 4 bytes (in i386)
to 1, which will add as we when are doubling USB_MAXCHILDREN
(with 16 the size of that array is 64 bytes, with 31 would be 128; by
using u8 that goes down to 31 bytes).

Jason Parekh 00081d3729 Input: appletouch - verious updates for MacBooks
Change a bit the finger detection method used by the appletouch
driver to reduce touchpad "jumpiness":

 - Adjust the method for detecting multiple fingers. Previously, it
   recognized a new finger when a low sensor reading is followed by
   a high sensor reading. The new method checks for 'humps' in the
   sensor readings, so there doesn't necessarily have to be a low
   sensor between two high sensors for two fingers to be triggered.
   This allows detecting presence of two fingers on the touchpad
   even when they touch each other.

 - Change absolute coordinate calculation to us to get rid of "jumps".
   Instead of using full value from a sensor once it passes the
   threshold subtract theshold value from the reading.

 - Allow adjusting threshold value via module parameter.

The patch doesn't seem to affect the Powerbooks but does greatly improve
the touchpad behaviour on the MacBooks.

Anssi Hannula 41ad5fbabd Input: HID - add a quirk for the Logitech USB Receiver
Logitech USB Receiver (046d:c101) has two interfaces. The first one
contains fields from HID_UP_KEYBOARD and HID_UP_LED, and the other one
contains fields from HID_UP_CONSUMER and HID_UP_LOGIVENDOR. This device
is used with multiple wireless Logitech products, including UltraX Media
Remote.

All fields on both interfaces are either keys or leds. All fields in the
first interface are marked as Absolute, while the fields in the second
interface are marked as Relative. Marking the keys as relative causes
hidinput_hid_event() to send release events right after key press
events.

The device has EV_REP set, so the userspace expects the device to send
repeat events if a key is held down. However, as hidinput_hid_event()
sends release events immediately, repeat events are not sent at all. In
fact, the userspace has no way of knowing if a key is being held down.

Fix this by adding a quirk for 046d:c101 which changes relative keys to
absolute ones.

Fix mcs7830 patch

The recent mcs7830 update to make the MII support sharable goofed various
pre-existing configurations in two ways:

  - it made the usbnet infrastructure reference MII symbols even
    when they're not needed in the kernel being built

  - it didn't enable MII along with the mcs7830 minidriver

This patch fixes these two problems.

However, there does seem to be a Kconfig reverse dependency bug in that MII
gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think
I've noticed that same problem in other situations too.  So the result can
mean kernels being bloated by stuff that's needlessly enabled ... better
than wrongly being disabled, but contributing to bloat.

Dominic Cerquetti deb8ee43a2 USB: xpad: dance pad support
Adds support for dance pads to the xpad driver. Dance pads require the
d-pad to be mapped to four buttons instead of two axes, so that
combinations of up/down and left/right can be hit simultaneously.
Known dance pads are detected, and there is a module parameter added
to default unknown xpad devices to map the d-pad to buttons if this is
desired. (dpad_to_buttons). Minor modifications were made to port the
changes in the original patch to a newer kernel version.

This patch was originally from Dominic Cerquetti originally written
for kernel 2.6.11.4, with minor modifications (API changes for USB,
spelling fixes to the documentation added in the original patch) made
to apply to the current kernel. I have modified Dominic's original
patch per some suggestions from Dmitry Torokhov. (There was nothing
in the patch format description about multiple From: lines, so I
haven't added myself.)

Grant Grundler 4550718f6c USB: input: extract() and implement() are bit field manipulation routines
extract() and implement() have brain damaged attempts to handle 32-bit wide
"fields".

The problem is the index math in the original code didn't clear all the
relevant bits.  (offset >> 5) only compensated for 32-bit index.  We need
(offset >> 6) if we want to use 64-bit loads.

But it was also wrong in that it tried to use quasi-aligned loads.  Ie
"report" was only incremented in multiples of 4 bytes and then the offset
was masked off for values greater than 4 bytes.  The right way is to
pretend "report" points at a byte array.  And offset is then only minor
adjustment for < 8 bits of offset.  "n" (field width) can then be as big as
24 (assuming 32-bit loads) since "offset" will never be bigger than 7.

If someone needs either function to handle more than 24-bits, please
document why - point at a specification or specific USB hid device - in
comments in the code.

extract/implement() are also an eyesore to read.  Please banish whoever
wrote it to read CodingStyle 3 times in a row to a classroom full of 1st
graders armed with rubberbands.  Or just flame them.  Whatever.  Globbing
all the code together on two lines does NOT make it faster and is Just
Wrong.

I've tested this patch on j6000 (dual 750Mhz PA-RISC, 32-bit 2.6.12-rc5). 
Kyle McMartin tested on c3000 (up 400Mhz PA-RISC, same kernel).  "p2-mate"

When working on the mcs7830, I noticed the need for a mutex in its
mdio_read/mdio_write functions. A related problem seems to be present
in the asix driver in the respective functions.

This introduces a mutex in the common usbnet driver and uses it
from the two hardware specific drivers.

This driver adds support for the DeLOCK USB ethernet adapter
and potentially others based on the MosChip MCS7830 chip.

It is based on the usbnet and asix drivers as well as the
original device driver provided by MosChip, which in turn
was based on the usbnet driver.

It has been tested successfully on an OHCI, but interestingly
there seems to be a problem with the mcs7830 when connected to
the ICH6/EHCI in my thinkpad: it keeps receiving lots of
broken packets in the RX interrupt. The problem goes away when
I'm using an active USB hub, so I assume it's not related to
the device driver, but rather to the hardware.

Duncan Sands 6a4f1b4135 speedtch: "extended reach"
The speedtouch modem setup code was reverse engineered many years
ago from a prehistoric windows driver. Less ancient windows drivers,
even those from a few years ago, perform extra initialization steps
which this patch adds to the linux driver.  David Woodhouse observed
that this initialization along with the firmware bin/sachu3/zzzlp2.eni
from the driver at
http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip
improves line sync speeds by about 20%.  He provided the original
patch, which I've modified to use symbolic names (BMaxDSL, ModemMode,
ModemOption) rather than magic numbers.  These names may not seem like
much of an improvement (after all, what is "ModemOption" exactly?),
but they do have one big advantage: they are the names used in the
windows registry.  I've made them available as module parameters.
Thanks are due to Aurelio Arroyo, who noticed the relationship
between these magic numbers and the entries in Phonebook.ini.

David Brownell 8442ae00d4 USB: ohci-pnx4008 build fixes
The OHCI bus glue for the Philips PNX chips is missing a few calls.

 - Bus suspend/resume were wrongly omitted in the original submission.
 - Two new calls were added since that glue was submitted:
     * Root hub irq enable call
     * Shutdown hook for usbcore

Plus usb_bus.hcpriv has now been removed from usbcore.

Chris Malley 91a9c9214e USB: Support for BT On-Air USB modem in cdc-acm.c
The patch below is a necessary workaround to support the BT On-Air USB modem, which
fails to initialise properly during normal probing thus:

Sep 30 17:34:57 sled kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
Sep 30 17:34:57 sled kernel: cdc_acm: probe of 1-1.2:1.0 failed with error -22

Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

David Howells 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.

Mark Assad 77dc2db6d1 [PATCH] itmtouch: fix inverted flag to indicate touch location correctly, correct white space
There is a bug in the current version of the itmtouch USB touchscreen
driver.  The if statment that checks if pressure is being applied to the
touch screen is now missing a ! (not), so events are no longer being
reported correctly.

The original source code for this line was as follows:

	#define UCP(x) ((unsigned char*)(x))
	#define UCOM(x,y,z) ((UCP((x)->transfer_buffer)[y]) & (z))

	...
	if (!UCOM(urb, 7, 0x20)) {

And was cleaned to:

	unsigned char *data = urb->transfer_buffer;
	....
	 if (data[7] & 0x20) {

(note the lack of '!')

This has been tested on an LG L1510BF and an LG1510SF touch screen.

Eric W. Biederman 2425c08b37 [PATCH] usb: fixup usb so it uses struct pid
The problem with remembering a user space process by its pid is that it is
possible that the process will exit, pid wrap around will occur.
Converting to a struct pid avoid that problem, and paves the way for
implementing a pid namespace.

Also since usb is the only user of kill_proc_info_as_uid rename
kill_proc_info_as_uid to kill_pid_info_as_uid and have the new version take
a struct pid.

Jeff Dike b68e31d0eb [PATCH] const struct tty_operations
As part of an SMP cleanliness pass over UML, I consted a bunch of
structures in order to not have to document their locking.  One of these
structures was a struct tty_operations.  In order to const it in UML
without introducing compiler complaints, the declaration of
tty_set_operations needs to be changed, and then all of its callers need to
be fixed.

This patch declares all struct tty_operations in the tree as const.  In all
cases, they are static and used only as input to tty_set_operations.  As an
extra check, I ran an i386 allyesconfig build which produced no extra
warnings.

53 drivers are affected.  I checked the history of a bunch of them, and in
most cases, there have been only a handful of maintenance changes in the
last six months.  serial_core.c was the busiest one that I looked at.

When a filesystem decrements i_nlink to zero, it means that a write must be

We're shortly going to have keep filesystems from being remounted r/o between
the time that this i_nlink decrement and that write occurs.

So, add a little helper function to do the decrements.  We'll tie into it in a
bit to note when i_nlink hits zero.
