2884fce165 drivers/rtc/rtc-rx8581.c: fix setdatetime
Fix the logic while writing new date/time to the chip.  The driver
incorrectly wrote back register values to different registers and even
with wrong mask.  The patch adds clearing of the VLF register, which
should be cleared if all date/time values are set.

c222fb2efa USB: usb-storage: fix initializations of urb fields
Commit 0ede76fcec, "USB: remove uses of
URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing
initialization of the transfer flags.  This caused initialization
failures in the ums-karma driver.  Fix the regression by zeroing it.

While at it, as Alan Stern points out, the initializers for
actual_length and status are handled by the core and error_count
only matters for isochronous urbs, so they don't need to be set here.
Remove them.

c30c791c94 USB: xhci: Set Mult field in endpoint context correctly.
The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has
different meanings, depending on the endpoint type.  If the endpoint is
isochronous, the bmAttributes field is the maximum number of packets
within a service interval that this endpoint supports.  If the endpoint is
bulk, it's the number of stream IDs this endpoint supports.

Only set the Mult field of the xHCI endpoint context using the
bmAttributes field if the endpoint is isochronous, and the device is a
SuperSpeed device.

47f19c0eed USB: adds Artisman USB dongle to list of quirky devices
When an attempt is made to read the interface strings of the Artisman
Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written
to the dmesg log (uhci_result_common: failed with status 440000) and the
dongle resets itself, resulting in a disconnect/reconnect loop.

Adding the dongle to the list of devices in quirks.c, with the same
quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D
joystick, stops the device from resetting and allows it to be used with
no problems.

2d1ee5904b USB: xhci: Set EP0 dequeue ptr after reset of configured device.
When a configured device is reset, the control endpoint's ring is reused.
If control transfers to the device were issued before the device is reset,
the dequeue pointer will be somewhere in the middle of the ring.  If the
device is then issued an address with the set address command, the xHCI
driver must provide a valid input context for control endpoint zero.

The original code would give the hardware the original input context,
which had a dequeue pointer set to the top of the ring.  This would cause
the host to re-execute any control transfers until it reached the ring's
enqueue pointer.  When issuing a set address command for a device that has
just been configured and then reset, use the control endpoint's enqueue
pointer as the hardware's dequeue pointer.

Assumption:  All control transfers will be completed or cancelled before
the set address command is issued to the device.  If there are any
outstanding control transfers, this code will not work.

809cd1cb80 USB: Fix USB3.0 Port Speed Downgrade after port reset
Without this fix, a USB 3.0 port is downgraded to full speed after a port
reset of a configured device.  The USB 3.0 terminations will be disabled
permanently, and USB 3.0 devices will always enumerate as full speed
devices, until the host controller is unplugged (if it is an ExpressCard)
or the computer is rebooted.

Fajun Chen traced this traced the speed downgrade issue to the port reset
and the interpretation of port status in USB hub driver code.  The hub
code was not testing for the port being a SuperSpeed port, and it fell
through to the else case of Full Speed.

The following patch adds SuperSpeed mapping from the port status, and
fixes the speed downgrade issue.

d1dc908a25 USB: xHCI: Fix another bug in link TRB activation change.
Commit 6c12db90f1 also seems to have
introduced a bug that is triggered when the command ring is about to wrap.
The inc_enq() function will not have moved the enqueue pointer past the
link TRB.  It is supposed to be moved past the link TRB in prepare_ring(),
which should be called before a TD is enqueued.  However, the
queue_command() function never calls the prepare_ring() function because
prepare_ring() is only supposed to be used for endpoint rings.  That means
the enqueue pointer will not be moved past the link TRB, and will get
overwritten.

The fix is to make queue_command() call prepare_ring() with a fake
endpoint status (set to running).  Then the enqueue pointer will get moved
past the link TRB.

f7512e7c4b serial: fix rs485 for atmel_serial on avr32
This patch fixes a build failure [1-4] in the atmel_serial code introduced by
patch the patch ARM: 6092/1: atmel_serial: support for RS485
communications (e8faff7330)

The build failure was caused by missing struct field and missing defines
for the avr32 board - the patch fixes this.

[2] http://kisskb.ellerman.id.au/kisskb/buildresult/2816418/ - still exists as of today
[3] http://kisskb.ellerman.id.au/kisskb/buildresult/2617511/ - first failure in Linus' tree - May 20th - did really no one notice this?!

e7b96f28c5 agp/intel: Use the correct mask to detect i830 aperture size.
BugLink: https://bugs.launchpad.net/bugs/597075

commit f1befe71fa introduced a
regression when detecting aperture size of some i915 adapters, e.g.,
those on the Intel Q35 chipset.

The original report: https://bugzilla.kernel.org/show_bug.cgi?id=15733
The regression report: https://bugzilla.kernel.org/show_bug.cgi?id=16294

According to the specification found at
http://intellinuxgraphics.org/VOL_1_graphics_core.pdf, the PCI config
space register I830_GMCH_CTRL is a mirror of GMCH Graphics
Control. The correct macro for isolating the aperture size bits is
therefore I830_GMCH_GMS_MASK along with the attendant changes to the
case statement.

127bd2ac91 drm/i915: Use the correct scanout alignment for fbcon.
This fixes a potential modesetting error during boot with plymouth on
Broadwater and Crestline introduced with 9df47c. The framebuffer was
hard-coding an alignment of 64K, but the modesetting code required the
documented alignment of 128K. The result was that we would attempt to
unbind the pinned fbcon buffer, triggering an ERROR and ultimately
failing the mode change.

9934c13298 drm/i915: make sure eDP panel is turned on
When enabling the eDP port, we need to make sure the panel is turned on
after training the link.  If we don't, it likely won't come back after
suspend or may not come up at all.

For unknown reasons, unlocking the panel regs before initiating a power
on sequence is necessary.  There are known bugs in the PCH panel
sequencing logic, apparently this is one possible workaround.

6ba770dc5c drm/i915: Make G4X-style PLL search more permissive
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC
reference clock.

More generally, the 0.488% tolerance used before is just too tight to
reliably find a PLL setting.  I extracted the search algorithm and
modified it to find the dot clocks with maximum error over the valid
range for the given output type:

http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c

This gave:

Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571)
Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524)
Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488)
Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529)
Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488)
Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448)
Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478)
Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449)
Worst dotclock for G4X DL-LVDS refclk is 224000kHz (error 0.00510)
