I've got one of these devices on my desk and it seems that it suffers from
the ABS_Z/ABS_RX issue that we've seen in other devices before. This patch
uses the same reasoning as 9db630b4 ("HID: add multi-input quirk for NextWindow
Touchscreen").

The Behavior Tech. Computer Corp. (BTC) remote branded as "Emprex 3009URF III
Vista Remote Controller" uses non-standard mappings for all of its 'special
purpose' keys (0xffbc usage page).  This patch modifies the existing
hid-topseed quirky driver to support both remotes in order to prevent
proliferation of in-kernel quirky drivers until such a time that udev remapping
works with these devices.  Tested successfully with both the "Emprex" remote
and the "CyberLink" remote originally supported by the hid-topseed driver.

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.

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

covers only USB keyboards (and then only those supporting the boot
protocol).

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.

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.
