When converting this to the new wait_for macro I inverted the wait
condition, which causes all sorts of problems. So correct it to fix
several failures caused by the bad wait (flickering, bad output
detection, tearing, etc.).

Xen events are logically edge triggered, as Xen only calls the event
upcall when an event is newly set, but not continuously as it remains set.
As a result, use handle_edge_irq rather than handle_level_irq.
This has the important side-effect of fixing a long-standing bug of
events getting lost if:
- an event's interrupt handler is running
- the event is migrated to a different vcpu
- the event is re-triggered
The most noticable symptom of these lost events is occasional lockups
of blkfront.
Many thanks to Tom Kopec and Daniel Stodden in tracking this down.

IPIs and VIRQs are inherently per-cpu event types, so treat them as such:
- use a specific percpu irq_chip implementation, and
- handle them with handle_percpu_irq
This makes the path for delivering these interrupts more efficient
(no masking/unmasking, no locks), and it avoid problems with attempts
to migrate them.

If netconsole is in use, there is a possibility for deadlock in 3c59x between
boomerang_interrupt and boomerang_start_xmit. Both routines take the vp->lock,
and if netconsole is in use, a pr_* call from the boomerang_interrupt routine
will result in the netconsole code attempting to trnasmit an skb, which can try
to take the same spin lock, resulting in deadlock.
The fix is pretty straightforward. This patch allocats a bit in the 3c59x
private structure to indicate that its handling an interrupt. If we get into
the transmit routine and that bit is set, we can be sure that we have recursed
and will deadlock if we continue, so instead we just return NETDEV_TX_BUSY, so
the stack requeues the skb to try again later.

Add ftdi product ID for Lenz LI-USB, a model train interface. This
was NOT tested against 2.6.35, but a similar patch was tested with the
CentOS 2.6.18-194.11.1.el5 kernel. It wasn't clear to me what
ordering is being used in ftdi_sio.c, so I inserted the ID after another
model train entry(SPROG_II).

This patch fixes a isoc transfer bug reported by Sander Eikelenboom.
When ep->skip is set, endpoint ring dequeue pointer should be updated
when processed every missed td. Although ring dequeue pointer will also
be updated when ep->skip is clear, leave it intact during missed tds
processing may cause two issues:
1). If the very next valid transfer following missed tds is a short
transfer, its actual_length will be miscalculated;
2). If there are too many missed tds during transfer, new inserted tds
may found the transfer ring full and urb enqueue fails.

The code to increment the TRB pointer has a slight ambiguity that could
lead to a bug on different compilers. The ANSI C specification does not
specify the precedence of the assignment operator over the postfix
operator. gcc 4.4 produced the correct code (increment the pointer and
assign the value), but a MIPS compiler that one of John's clients used
assigned the old (unincremented) value.
Remove the unnecessary assignment to make all compilers produce the
correct assembly.

The reset state of twl4030-usb is not sleeping, it starts
up awaken and we need to disable it if we have booted
with a disconnected cable to avoid over consumption on
the default state.
To avoid problems later, we read the current state of the
transceiver from the PHY_PWR_CTRL register. The bootloader
can, anyways, put the device to sleep before us.

If we can't read the firmware for a device from the disk, and yet the
device already has a valid firmware image in it, we don't want to

thing to do.

The patch with title below makes reference count of usb serial module
always more than one after driver is bound.
USB-BKL: Remove BKL use for usb serial driver probing
In fact, the patch above only replaces lock_kernel() with try_module_get()
, and does not use module_put() to do what unlock_kernel() did, so casue leak
of reference count of usb serial module and the module can not be unloaded
after serial driver is bound with device.
This patch fixes the issue, also simplifies such things:
-only call try_module_get() once in the entry of usb_serial_probe()
-only call module_put() once in the exit of usb_serial_probe

I recently bought a i-gotU USB GPS, and whilst hunting around for linux
support discovered this post by you back in 2009:
http://kerneltrap.org/mailarchive/linux-usb/2009/3/12/5148644
>Try the navman driver instead. You can either add the device id to the

> modprobe navman
> echo -n "0x0df7 0x0900" > /sys/bus/usb-serial/drivers/navman/new_id
>
> and then plug your device in and see if that works.
I can confirm that the navman driver works with the right device IDs on
my i-gotU GT-600, which has the same device IDs. Attached is a patch
adding the IDs.

The ISP1760 has some timing requirements where it has to delay a short
period after a write to a register has started. However, this delay is
from the time the write hits the USB chip (the ISP1760), not from the
time where the processor started processing the write. So on a quick
enough processor, it is sometimes possible for the write to not hit the
device before we start delaying, and we then violate the part's timing
requirements, so things stop working.
To avoid all this, insert a write barrier after the register write and
before the timing delay/register read so we can guarantee we only start
counting time after the write has hit the device.

We're trying to test for the the end of the loop here. "format" is
never NULL. We don't know what "format->fcc" is because we're past the
end of the loop and I think "fmt->fmt.pix.pixelformat" comes from the
user so we don't know what that is either. It works, but it's cleaner
to just test to see if (i == ARRAY_SIZE(uvc_formats).
