The failure to map user-space pages leads to scsi command leak. It can
happens mostly because of user-space daemon bugs (or OOM). This patch
makes tgt just notify a LLD of the failure with sense when
blk_rq_map_user() fails.

This patch simplify the way to notify LLDs of the command completion
and addresses the following sense buffer problems:

- can't handle both data and sense.
- forces user-space to use aligned sense buffer

tgt copies sense_data from userspace to cmnd->sense_buffer (if
necessary), maps user-space pages (if necessary) and then calls
host->transfer_response (host->transfer_data is removed).

scsi tgt breaks up a command into multple scatterlists
if we cannot fit all the data in one. This was because
the block rq helpers did not support large requests and
because we can get a command of any old size so it is
hard to preallocate pages for scatterlist large enough
(we cannot really preallocate pages with the bio map
user path). In 2.6.20, we added large request support to
the block layer helper, blk_rq_map_user. And at LSF,
we talked about increasing SCSI_MAX_PHYS_SEGMENTS for
scsi tgt if we want to support really really :) large
(greater than 256 * PAGE_SIZE in the worst mapping case)
requests.

The only target currently implemented does not even support
the multiple scatterlists stuff and only supports smaller
requests, so this patch just coverts scsi tgt to use
blk_rq_map_user.

Russell King points out that it's obviously bogus, and I have to agree.
Not only does "irq" not even exist in that scope, but we obviously need
to free the irq that we actually requested, and that's IRQ_USB.

Delay the read of the EC status register until
after the event that caused it occurs -- otherwise
it is possible to read and act on stale status that was
associated with the previous event.

Do this with a perpetually incrementing "event_count" to detect
when a new event occurs and it is safe to read status.

There is no workaround for polling mode -- it is inherently
exposed to reading and acting on stale status, since it
doesn't have an interrupt to tell it the event completed.

Here is a patch adding the PID for the FT232RL to ftdi_sio. The patch
generates a warning during compilation because get_ftdi_divisor doesn't
explicitly handle the FT232RL with this patch, so I guess you don't want
to use it in its current state. It is all I could come up with with the
knowledge I have of the drivers at the moment, though, and I hope you
can have some use for it at least. It works fine with my DLP-TILT with
an FT232RL.

I encountered some problems with the airprime driver in use with a Novatel
Merlin XU870:

Closing an open Connection to e.g. /dev/ttyUSB0 doesn't reset the
RTS/DTR lines of the Modem.  Consequently, when I use minicom to
establish a connection by "ATD*99#" the modem doesn't hang up even if i
exit minicom and so I cannot reuse the modem unless I remove it and plug
it in again.

With the attached patch, the RTS/DTR lines are resetted on a close.  The
code was mainly taken from the option.c driver.

Convert all the port specific code in attach / shutdown to use the new
port_probe / port_register callbacks from device_register /
device_unregister allowing adding the sysfs attributes to be added at
the correct time and to the serial port device itself, instead of to
the unadorned usb device, avoiding a NULL dereference.

I've developed some devices with FTDI chips (FT232xx). FTDI was so kind
to give some own PID's which I can use together with their VID. Some of
the devices are already very popular here and I have customers from
universities, institutes .....

I use the FTDI VID 0x0403. My PID's are:

0xff38 - IBS US485 (USB<-->RS422/485 interface)
0xff39 - IBS PIC-Programmer
0xff3a - IBS Card reader for PCMCIA SRAM-cards
0xff3b - IBS PK1 - Particel counter
0xff3c - IBS RS232 - Monitor
0xff3d - APP 70 (dust monitoring system)
0xff3e - IBS PEDO-Modem (RF modem 868.35 MHz)
0xff3f - future device

The company is "IBS Ing.-Buero Schleusener".
