This patch adds IXP465 into the list of known devices and
adds IXP425 and IXP465 to the list of devices that have cfr. This
is not described in the hardware documentation, but without
it driver won't work.

Workaround (#if 1) that seemed to get rid of lost
status irqs is disabled for IXP4XX as it caused freezes
during testing of control messages. No lost irqs are
visible on IXP4XX.

Driver survived tests running over night without any
visible problems.

When closing the device, the driver acquires/release twice the

If either the driver's open() method or try_module_get() fails, we need to
set 'tty->driver_data' and 'port->tty' to NULL in serial_open(), otherwise
we'll get an OOPS in usb_device_disconnect() when the device is disconnected.

This is a new driver for the Cypress CY7C63xxx mirco controller series.
It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus
GmbH.  It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I
ported to kernel 2.6 using sysfs. I intend to support more controllers
of this family (and more features) as soon as I get hold of the required
IDs etc. Please see the source code's header for more information.

This update contains one bug fix: some lines can come out truncated,
because of the safety cutoff. This happened because I forgot to update
the size when status packets began to be printed.

The rest is:
 - Comments updates
 - Allow snooping with pkmap on x86_64, which is cache-coherent
 - Enlarge event buffers (certainly we can have a couple of pages)
 - Add event counter

This patch (as707) improves the FSBR operation in uhci-hcd by turning it
off more quickly when it isn't needed.  FSBR puts a noticeable load on a
computer's PCI bus, so it should be disabled as soon as possible when it
isn't in use.  The patch leaves it running for only 10 ms after the last
URB stops using it, on the theory that this should be long enough for a
driver to submit another URB if it wants keep FSBR going.

This patch (as706) removes the private hc_inaccessible flag from

This patch (as705) contains a small set of updates for uhci-hcd written
mostly by Dave Brownell:

  * Root hub suspend messages come out labeled as root hub messages;
    PCI messages should only come out when the pci device suspends.

  * Rename the reset() method to better match its init() role

  * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub
    suspend/resume errors.

  * When an URB fails, associate the message with the usb device not
    the host controller (it still hides endpoint and direction)

This fixes coverity Bug #390.

With the following code

	ret = ep->branch = balance(isp116x, ep->period, ep->load);
	if (ret < 0)
		goto fail;

the problem is that ret and balance are of the type int, and ep->branch is u16.
so the int balance() returns gets reduced to u16 and then converted to an int again,
which removes the sign. Maybe the following little c program can explain it better:

In ub, nobody upstream should ever see half-constructed disks before
