93cffffc18 [media] media: rc: fix decoder module unloading
Currently, if a decoder module is unloadad, the respective protocol
is still shown as enabled (if it was enabled before).
Fix this by resetting the respective protocol bits if a decoder
module is unloaded.

1efc21701d [media] Add support for dvb usb stick Hauppauge WinTV-soloHD
This patch adds support for the DVB-T/C/T2 usb stick WinTV-soloHD from
Hauppauge. It adds the usb ID 2040:0264 Hauppauge to the cards of the
driver em28xx.

I successfully tested DVB-T/C and the IR remote control with the
firmware dvb-demod-si2168-b40-01.fw.

769161fd2d [media] media: omap4iss: csi2: Fix IRQ handling when stopping module
When stopping the CSI2 receiver the s_stream handler will wait for the
IRQ handler to notice the stop request. The receiver, automatically
disabled by the hardware after each frame, is then not reenabled by the
IRQ handler as it returns immediately.

As the IRQ handler check is performed before handling the context IRQ,
the context IRQ source isn't cleared, and the CSI2 IRQ is then fired
again immediately. The IRQ handler then fails to notice that the module
is being stopped, processes the IRQ normally and reenables the CSI2
hardware.

The problem goes unnoticed at stream stop time, but depending on the IRQ
and s_stream scheduling timings, the CSI2 receiver can end up being
hanged and will not produce any interrupt the next time it gets enabled,
despite being soft-reset then.

Fix this by checking for module stop after clearing the context IRQ
source.

8afe97be37 [media] uvcvideo: Enable UVC 1.5 device detection
UVC 1.5 devices report a bInterfaceProtocol value set to 1 in their
interface descriptors. The uvcvideo driver only matches on
bInterfaceProtocol 0, preventing those devices from being detected.

More changes to the driver are needed for full UVC 1.5 compatibility.
However, at least the UVC 1.5 Microsoft Surface Pro 3 cameras have been
reported to work out of the box with the driver with an updated match
table.

Enable UVC 1.5 support in the match table to support the devices that
can work with the current driver implementation. Devices that can't will
fail, but that's hardly a regression as they're currently not detected
at all anyway.

LEDs and force-feedback on controllers can persist even when the system is in
standby.  Additionally, the state of the controllers on resume may be different
from the state they were in at the time when they were suspended (ie. LEDs are
cleared on resume).

This implements the suspend and resume callbacks which saves and clears the
state of the LEDs on suspend and restores them on resume.  Force-feedback is
stopped on suspend but not automatically restored on resume until a new event is
received to avoid potentially damaging hardware.

USB Sixaxis and navigation controllers must be reinitialized when the hardware
is reset on resume or they won't send any input reports.

22bc862568 [media] rcar_vin: Remove obsolete platform data support
Since commit 3d7608e4c1 ("ARM: shmobile: bockw: remove legacy
board file and config"), Renesas R-Car SoCs are only supported in
generic DT-only ARM multi-platform builds.  The driver doesn't need to
use platform data anymore, hence remove platform data configuration.

a71daaa10e [media] move media platform data to linux/platform_data/media
Now that media has its own subdirectory inside platform_data,
let's move the headers that are already there to such subdir.

After moving those files, the references were adjusted using this
script:

    MAIN_DIR="linux/platform_data/"
    PREV_DIR="linux/platform_data/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);
	echo "Handling documentation..." >&2;
	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done"
	);
    ) >script && . ./script

03c02807e2 KVM: s390: fix pfmf intercept handler
The pfmf intercept handler should check if the EDAT 1 facility
is installed in the guest, not if it is installed in the host.

5967c17b11 KVM: s390: enable SIMD only when no VCPUs were created
We should never allow to enable/disable any facilities for the guest
when other VCPUs were already created.

kvm_arch_vcpu_(load|put) relies on SIMD not changing during runtime.
If somebody would create and run VCPUs and then decides to enable
SIMD, undefined behaviour could be possible (e.g. vector save area
not being set up).

581b7f158f x86/cpu: Fix SMAP check in PVOPS environments
There appears to be no formal statement of what pv_irq_ops.save_fl() is
supposed to return precisely.  Native returns the full flags, while lguest and
Xen only return the Interrupt Flag, and both have comments by the
implementations stating that only the Interrupt Flag is looked at.  This may
have been true when initially implemented, but no longer is.

To make matters worse, the Xen PVOP leaves the upper bits undefined, making
the BUG_ON() undefined behaviour.  Experimentally, this now trips for 32bit PV
guests on Broadwell hardware.  The BUG_ON() is consistent for an individual
build, but not consistent for all builds.  It has also been a sitting timebomb
since SMAP support was introduced.

Use native_save_fl() instead, which will obtain an accurate view of the AC
flag.
