Patch originally written by Konrad. Rebased on current linux media tree.
Under Xen, vmalloc_32() isn't guaranteed to return pages which are really
under 4G in machine physical addresses (only in virtual pseudo-physical
addresses). To work around this, implement a vmalloc variant which
allocates each page with dma_alloc_coherent() to guarantee that each
page is suitable for the device in question.

drx39xxj_set_lna() and drx39xxj_set_frontend() set LNA. Instead of
duplicating LNA configure code, change to use drxj_set_lna_state()
which sets LNA to the caller requested state (on or off).

Some fe drivers will have to do additional initialization
in their fe ops.init interfaces when called during resume.
Without the additional initialization, fe and tuner driver
resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME
is necessary to detect resume case. This patch adds a new
define and changes dvb_frontend_resume() to set it prior to
calling fe init and tuner init calls and resets it back to
DVB_FE_NO_EXIT once fe and tuner init is done.

Change em28xx_dvb_fini() to set fe exit flag to DVB_FE_DEVICE_REMOVED
when device is disconnected. em28xx maintains device disconnect status
in em28xx device. fe drivers will be able to now check the fe exit
status to avoid accessing the device, from their release interfaces
when called from disconnect path. This change depends on dvb-core
change that exports fe exit flag by moving it from fepriv to fe.

Some fe drivers attempt to access the device for power control from
their release routines. When release routines are called after device
is disconnected, the attempts fail. fe drivers should avoid accessing
the device, from their release interfaces when called from disconnect
path. dvb-frontend maintains exit flag to keep track when fe device is
disconnected in its private data structures. Export the flag in fe to
enable drivers to check the device status from their release interfaces.

em28xx uses resume interface as its reset_resume interface.
If usb device is reset during suspend, reset_resume doesn't

Devices using resolvable private addresses are required to provide
an identity resolving key. These devices can not be found using
the current controller white list support. This means if the kernel
knows about any devices with an identity resolving key, the white
list filtering must be disabled.
However so far the kernel kept identity resolving keys around even
for devices that are not using resolvable private addresses. The
notification to userspace clearly hints to not store the key and
so it is best to just remove the key from the kernel as well at
that point.
With this it easy now to detect when using the white list is
possible or when kernel side resolving of addresses is required.

The Bluetooth controller can use a white list filter when scanning
to avoid waking up the host for devices that are of no interest.
Devices marked as reporting, direct connection (incoming) or general
connection are now added to the controller white list. The update of
the white list happens just before enabling passive scanning.
In case the white list is full and can not hold all devices, the
white list is not used and the filter policy set to accept all
advertisements.
Using the white list for scanning allows for power saving with
controllers that do not handle the duplicate filtering correctly.

Adding a function, and associated calls, to flush writes to (read) the LPIC
MAC register before entering the shutdown flow. This fixes the problem
of the PHY never negotiating a 100M link (if both sides of the link support
EEE and 100M link) when Runtime PM is enabled.

The process of shutting down the system causes a call to the close PM
callback. The reset in close causes a loss of link, and the resultant
LSC interrupt causes the Runtime PM idle callback to be called. The
check for link (while link is down) in the idle callback is wiping the
information about the EEE ability of the link partner. The information is
still gone when the PHY is powered back up in the shutdown flow. This
causes EEE in S5 to fail when Runtime PM is active.
Save the link partner's EEE ability in the idle callback so that a Runtime
PM event will not cause a loss of this information.

On I217 and newer hardware, EEE is enabled in the PHY by the software
when link is up and disabled by the hardware when link is lost.
To enable EEE in Sx (When both ends of the link support, and are enabled
for, EEE and 100Mbps), we need to disable LPLU and configure the PHY to
automatically enable EEE when link is up, since there will be no software
to complete the task.
To configure this in the PHY, the Auto Enable LPI bit in the Low Power
Idle GPIO Control register must be set. For normal operation in S0, this
bit must be cleared.

This tries to make them more like other remotes, and/or
the button labels.
Notably, the (>>) button is made KEY_FASTFORWARD, which is the
correct opposite of (<<)'s KEY_REVERSE. (It was KEY_FORWARD,
something else entirely.)
Likewise, KEY_STOP is the Sun keyboard "interrupt program" key;
the media key is KEY_STOPCD.
A restriction is that I try to avoid keycodes above 255, as the X11
client/server protocol is limited to 8-bit key codes. If not for
this, I would have used the KEY_NUMERIC_x codes for the numbers.

of actual payload. The 4 bytes are:
data[0] = 0x14
data[1] = data[2] + data[3] + 0xd5 (a checksum byte)
data[2] = the raw scancode (plus toggle bit in msbit)
data[3] = channel << 4 (the low 4 bits must be zero)

The hole point of IR_dprintk() is that, once a level is
given at debug parameter, all enabled IR parsers will show their
debug messages.
While converting it to dynamic_printk might be a good idea,
right now it just makes very hard to debug the drivers, as
one needs to both pass debug=1 or debug=2 to rc-core and
to use the dynamic printk to enable all the desired lines.
That doesn't make sense!
So, revert to the old way, as a single line is changed,
and the debug parameter will now work as expected.

In the function ixgbe_get_swfw_sync_semaphore, an incorrect
check was treating success as failure and vice-versa. This led
to manipulating the IXGBE_SWFW_SYNC register without holding
the software semaphore first, which is an error. In addition,
if getting the REGSMP bit in the IXGBE_SW_FW_SYNC register
timed out, no error code would be returned, making the caller
think that it had successfully acquired the lock. Fix both of
those issues and clean up the function a bit, such as make the
