[Bluetooth] Add open and close callbacks for HID device
The open and close callbacks for the HID device are not optional, but
for the Bluetooth HID report mode support it is enough to add empty

move_native_irqs tries to do the right thing when migrating irqs
by disabling them. However disabling them is a software logical
thing, not a hardware thing. This has always been a little flaky
and after Ingo's latest round of changes it is guaranteed to not
mask the apic.
So this patch fixes move_native_irq to directly call the mask and
unmask chip methods to guarantee that we mask the irq when we
are migrating it. We must do this as it is required by
all code that call into the path.
Since we don't know the masked status when IRQ_DISABLED is
set so we will not be able to restore it. The patch makes the code
just give up and trying again the next time this routing is called.

[PATCH] x86_64 irq: Safely cleanup an irq after moving it.
The problem: After moving an interrupt when is it safe to teardown
the data structures for receiving the interrupt at the old location?
With a normal pci device it is possible to issue a read to a device
to flush all posted writes. This does not work for the oldest ioapics
because they are on a 3-wire apic bus which is a completely different
data path. For some more modern ioapics when everything is using
front side bus delivery you can flush interrupts by simply issuing a
read to the ioapic. For other modern ioapics emperical testing has
shown that this does not work.
So it appears the only reliable way to know the last of the irqs from an
ioapic have been received from before the ioapic was reprogrammed is to
received the first irq from the ioapic from after it was reprogrammed.
Once we know the last irq message has been received from an ioapic
into a local apic we then need to know that irq message has been
processed through the local apics.

V4L/DVB (5166): Remove obsolete alias defines of CONFIG_* settings
The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly. To work around
this, makefiles would define some new macro based on the setting of a
config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary. This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

V4L/DVB (5164): Compat: Handle input_register_device() change and some others
input_register_device() was changed to return an error code instead of
being void in 2.6.15. Handle it with a macro wrapper in config.h. For
this to work, linux/input.h must be included before config.h. This
required some trivial header re-ordering in budget-ci.c and ttusb_dec.c.
In kernel 2.6.15-rc1 a helper function called setup_timer() was added to
linux/timer.h. Add to compat.h, but require that linux/timer.h be
included first to give the definition of struct timer_list.
A new 4GB DMA zone, __GFP_DMA32, was added in 2.6.15-rc2. Alias it to
__GFP_DMA on older kernels.
Handle another 2.6.15 "input_dev->dev to input_dev->cdev.dev" change for
some recently added code in cinergyT2.c.

V4L/DVB (5163): Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTER
Before, root privileges were only needed to set hardware registers, not
to read them. On some hardware, reading from the wrong place at the
wrong time can hang the machine. So, to be consistent, root privileges
are required to read registers on all hardware.

V4L/DVB (5162): Change VIDIOC_DBG_[SG]_REGISTER ioctls' reg address to 64 bits
Maybe someday there will be a device with a register address space >
32-bits, or maybe an i2c device which uses a protocol > 4 bytes long to
address its registers.
V4L/DVB (5157): Set phys, bustype, version, vendor and product for input device
Add phys-string, bustype, version, vendor and product to help udev and
others using EVIOCPHYS ioctl to identify the input device node.
