+Subject: i2c/tsl2550: Fix lux value in extended mode
+
+From: Michele Jr De Candia <michele.decandia@valueteam.com>
+
+commit 5f5bfb09d81c9a1d26238ae6668e584c14ae3daf upstream.
+
+According to the TAOS Application Note 'Controlling a Backlight with
+the TSL2550 Ambient Light Sensor' (page 14), the actual lux value in
+extended mode should be obtained multiplying the calculated lux value
+by 5.

+Subject: ipv6: reassembly: use seperate reassembly queues for conntrack and local delivery
+
+From: Patrick McHardy <kaber@trash.net>
+
+commit 0b5ccb2ee250136dd7385b1c7da28417d0d4d32d upstream.
+
+Currently the same reassembly queue might be used for packets reassembled
+by conntrack in different positions in the stack (PREROUTING/LOCAL_OUT),
+as well as local delivery. This can cause "packet jumps" when the fragment
+completing a reassembled packet is queued from a different position in the
+stack than the previous ones.
+
+Add a "user" identifier to the reassembly queue key to seperate the queues
+of each caller, similar to what we do for IPv4.

+Subject: S390: dasd: support DIAG access for read-only devices
+
+From: Stefan Weinhuber <wein@de.ibm.com>
+
+commit 22825ab7693fd29769518a0d25ba43c01a50092a upstream.
+
+When a DASD device is used with the DIAG discipline, the DIAG
+initialization will indicate success or error with a respective
+return code. So far we have interpreted a return code of 4 as error,
+but it actually means that the initialization was successful, but
+the device is read-only. To allow read-only devices to be used with
+DIAG we need to accept a return code of 4 as success.
+
+Re-initialization of the DIAG access is also part of the DIAG error
+recovery. If we find that the access mode of a device has been
+changed from writable to read-only while the device was in use,
+we print an error message.

+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+commit 04a1e62c2cec820501f93526ad1e46073b802dc4 upstream.
+
+The loop condition is fragile: we compare an unsigned value to zero, and
+then decrement it by something larger than one in the loop.  All the
+callers should be passing in appropriately aligned buffer lengths, but
+it's better to just not rely on it, and have some appropriate defensive
+loop limits.
