Clean up irq urb when not enough memory is available.

This patch for the UHCI driver changes the test for over current inputs,
which can cause false Resume indications with some of Intel's USB
controllers.  Previously the code only checked for one specific controller
chip, but now another one has turned up that exhibits the same flaw.  It
seems best just to check for Intel being the manufacturer, especially
since it doesn't hurt to check for the condition when it isn't present or
is only temporary.

This patch makes the sddr55 subdriver use proper DMA I/O buffering.

This patch makes the sddr09 subdriver use proper DMA I/O buffering.

usblcd registers a device before all buffers are allocated leading
to a race resulting in NULL pointers being followed.
This fixes it.

  - #ifdefs out some code that never runs on the pxa
  - catches "alloc_etherdev Jihad" changes I somehow missed

registering a device only partially initialised is quite bad an
idea.

this fixes the completion handler for the interrupt urb in hpusbscsi.

Here are more user-reported updates for unusual_devs.h.

writing urb->status is a no go area for drivers.

registering the device before setting the interface data can lead
to a null pointer being followed in open(). This patch fixes that.

this patch adds new vendor/product ids for Avision, Canon, HP,
Microtek and Relisys scanners.

This patch from Oliver Neukum fixes a race between open and
probe.

The original code needed some updates to work properly with
the USB Device Controller found in Intel's PXA 2xx processors.

  - SET_INTERFACE and SET_CONFIGURATION involve hardware
    automagic:  all endpoints get reset.  This is a PITA,
    and will likely get more work.  (Seems like the reset
    is only partial, hosts need to CLEAR_HALT themselves...)

    What this does is to handle -ECONNABORTED notifications
    from pxa2xx_udc, in those cases.  In general, gadget
    drivers need to reset endpoints themselves, since the
    lower levels (hardware!) won't know how the endpoints
    are allocated between interfaces and altsettings.

  - The config symbol will be CONFIG_USB_PXA2XX, since the
    same controller (modulo errata) is in several processors
    other than the "older" pxa250.

  - This also adds an "i/o pattern" parameter, so that it
    can continue to use the "all zeroes" pattern or switch
    to something else.  The initial "something else" is an
    easily predicted "mod63" pattern.

Not all gadget controllers support ep2in-bulk and ep2out-bulk,
unlike the EZ-USB (non-FX2) devices or the net2280.

So this patch teaches "usbtest" how to look at the descriptors
it's given, and use the appropriate endpoints.  This helps
support Linux test devices using hardware like the pxa2xx UDC,
and other controllers.

The original code needed some updates to work properly with
the USB Device Controller found in Intel's PXA 2xx processors.

   - SET_INTERFACE is effectively unusable.  So the driver
     now has a "minimalist" mode, with none of the bells and
     whistles of CDC.

   - The config symbol will be CONFIG_USB_PXA2XX, since the
     same controller (modulo errata) is in several processors
     other than the "older" pxa250.

For the record, that "minimalist" mode was the original idea
behind this driver ... implementing CDC was a win for interop
since most non-MSFT host operating systems support it already,
without needing a new driver.

There were also a few other minor updates:

   - Net2280:  queue depth shrank a bit, don't use the same
     endpoint numbers for the IN and OUT sides.  (CATC doesn't
     let filters consider direction, just numbers.)

   - Join the Jihad!  Abolish register_netdev()!!  This just
     nests the gadget-private data structures inside the
     netdev data structure, instead of the other way around.

   - Minor cleanups.

I noticed that Viro's "use alloc_etherdev" patch left a
small problem:  only "usbnet" did SET_NETDEV_DEV, and
that used the wrong driver model device.

This has all the usb network drivers use SET_NETDEV_DEV,
so the /sys/class/net/*/{device,driver} files link to the
relevant usb interface and to its device driver.

Two small updates:

  - Report short control reads correctly in an exotic case
    that our regression tests cover.  (Haven't run them with
    ohci for a long time, it seems...)

  - IRQ non-delivery bugs (ACPI, APIC, etc) can prevent urbs
    from unlinking.  This prints a warning when that sort of
    non-USB bug is biting.

This solves the module unload problem for some usb-serial drivers
(like visor.c and ftdi_sio.c), and makes usb drivers much simpler.

This patch removes all of the mode-translation logic.  It's no longer
needed, as the upper-level drivers now all issue the proper 10-byte
commands.  This is a large patch, but what it's doing is removing a great
deal of unneeded code -- about 650+ lines removed, according to diffstat.

Those of you who are having some trouble getting your DVD-RAMs detected
properly should have all your problems solved by an upcoming patch from the
SCSI folks.  It may look like that problem is related to this patch, but it
isn't -- it's a side-effect of another SCSI patch to consolidate code.

Special thanks to James Bottomley for being patient enough to work with me
on these issues on the SCSI layer.

This, BTW, makes US_FL_MODE_XLATE a NOP.  The symbol is kept for the
purpose of allowing unusual_devs.h to be consistent between 2.4 and 2.5

There are still a few places where more code could (potentially) be
removed.  I need to mull over the UFI specification to be sure, tho.

This patch converts the ISD200 and Jumpshot drivers to use the new DMA-safe
buffer.


I'd also like to take a moment to thank Alan Stern, who writes many of
these patches.  Without his help, many of the improvements everyone has
seen over the 2.5.x series would not have been possible.

This patch includes quite a few changes and updates for the shwdt driver (which
brings it in sync with LinuxSH CVS HEAD). This fixes up support for the SH-2,
and also fixes up some timer brain-damage.

This patch updates the sh-specific hd64465 pcmcia driver for the new API, as
well as fixing up some other issues (such as remap_page_range() abuse -- we
remap through P3 area instead) which caused it not to compile. Changes by
Dominik Brodowski and myself.

Here's an update for pvr2fb (with a patch this time), which makes it compile
again.

ppc64 machines can have PCI bus numbers larger than 8 bits, but it looks
like pci_device_to_OF_node already handles this case, in both 2.4 and
2.5.

We just need the space to store them.

This solves the unresolved symbol problem with modular intermezzo.  Also
update the MAINTAINERS entry.

send_IPI_self is needed to resend irqs with IRQ_PENDING status when
enabled.

Checked with Ingo, and it's in 2.4-ac for some time.

This should fix ide lost interrupts on UP with IO-APIC

Ide trigers it this way:
 - disable_irq
 - do stuff that triggers IRQ.
 - irq is IRQ_PENDING
 - enable_irq
 - IRQ is lost, needs to be resend.

I'll send the patch to fixup IDE disable_irq logic to Bart.

From Flavio B. Leitner. <fbl@netbank.com.br>

Fix a memory leak and an unchecked return code in the busmouse driver.

From Daniele Bellucci <bellucda@tiscali.it>.

Check the copy_to_user() return code in read_profile().

From Jorn Engel <joern@wohnheim.fh-wedel.de> and Randy Dunlap.

It reduces stack usage in the WAN router by about 0x500 bytes
(from 0x520 to 0x24 when I did it in April).

This fixes this warning:

  syncppp.c:165: warning: function declaration isn't a prototype

by adding "void" as the function parameter list.

This fixes one place where I missed the replacing dcache_lock with
vfsmount_lock in put_namespace().

Tested with CLONE_NEWNS flag also.
