Add two quirks to make it possible for usbhid module options to
override whether a device is ignored (HID_QUIRK_NO_IGNORE) and
whether to connect a hiddev device (HID_QUIRK_HIDDEV_FORCE).
Passing HID_QUIRK_NO_IGNORE for your device means that it will
not be ignored by the HID layer, even if present in a blacklist.
HID_QUIRK_HIDDEV_FORCE will force the creation of a hiddev for that
device, making it accessible from user-space.
Tested with an Apple IR Receiver, switching it from using appleir
to using lirc's macmini driver.

From my review of the way the unused bits of report are being zeroed,
it seems like there must be a bug. Currently, the zeroing is done
in hid_output_field and it covers any bits between the last used bit
and the end of the byte. But in case of, say, my keyboard, NumLock is
mask 0x01 and CapsLock is 0x02. Invoking hid_output_field for NumLock
definitely zeroes across CapsLock. The only reason this works is that
the fields are sorted by the offset.
It would be more correct and simpler to zero-fill the buffer into
which the fields are set.
The patch is tested with an IBM keyboard that is improperly sensitive
to out-of-report pad bits, the extra bits are still zeroed and the
fields continue to work as expected. It is also tested with good
keyboards.
In case, a related bug in RHEL 5 is tracked with Red Hat bug 513934.

This patch (as1365) enables remote wakeup by default for USB keyboard
devices. Keyboards in general are supposed to be wakeup devices, but
the correct place to enable it depends on the device's bus; no single
approach will work for all keyboard devices. In particular, this
covers only USB keyboards (and then only those supporting the boot
protocol).

The attribute allows to change reporting speed of tablet from userspace through

High speed is the default setting. Using low speed is a workaround if you

Register debugfs entries before calling device_add() so debugfs entries are
already present when HID driver's probe function gets called on device hotplug.
Also undo debugfs entry registration if device_add() fails so status
HID_STAT_ADDED and debugfs registration status remain consistent and we don't
leak the debugfs entries.

This fixes corrupted CIPSO packets when SELinux categories greater than 127
are used. The bug occured on the second (and later) loops through the

is twice as long as the SELinux bitmap.

ahci: disable FPDMA auto-activate optimization on NVIDIA AHCI
|
|
Mike Cui reported that his system with an NVIDIA MCP79 (aka MCP7A)
chipset stopped working with 2.6.32. The problem appears to be that
2.6.32 now enables the FPDMA auto-activate optimization in the ahci
driver. The drive works fine with this enabled on an Intel AHCI so
this appears to be a chipset bug. Since MCP79 is a fairly recent
NVIDIA chipset and we don't have any info on whether any other NVIDIA
chipsets have this issue, disable FPDMA AA optimization on all NVIDIA
AHCI controllers for now.
Should address http://bugzilla.kernel.org/show_bug.cgi?id=14922

This commit adds a new feature, MULTIPORT. If the host supports this
feature as well, the config space has the number of ports defined for
that device. New ports are spawned according to this information.
The config space also has the maximum number of ports that can be
spawned for a particular device. This is useful in initializing the
appropriate number of virtqueues in advance, as ports might be
hot-plugged in later.
Using this feature, generic ports can be created which are not tied to
hvc consoles.
We also open up a private channel between the host and the guest via
which some "control" messages are exchanged for the ports, like whether
the port being spawned is a console port, resizing the console window,
etc.
Next commits will add support for hotplugging and presenting char
devices in /dev/ for bi-directional guest-host communication.
