+Subject: drivers/net/b44: Change to non-atomic bit operations on pwol_mask
+
+From: Fenghua Yu <fenghua.yu@intel.com>
+
+[ Upstream commit f11421ba4af706cb4f5703de34fa77fba8472776 ]
+
+Atomic operations that span cache lines are super-expensive on x86
+(not just to the current processor, but also to other processes as all
+memory operations are blocked until the operation completes). Upcoming
+x86 processors have a switch to cause such operations to generate a #AC
+trap. It is expected that some real time systems will enable this mode
+in BIOS.
+
+In preparation for this, it is necessary to fix code that may execute
+atomic instructions with operands that cross cachelines because the #AC
+trap will crash the kernel.
+
+Since "pwol_mask" is local and never exposed to concurrency, there is
+no need to set bits in pwol_mask using atomic operations.
+
+Directly operate on the byte which contains the bit instead of using
+__set_bit() to avoid any big endian concern due to type cast to
+unsigned long in __set_bit().

+
+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit 8f18eca9ebc57d6b150237033f6439242907e0ba ]
+
+The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad
+which is connected to an ITE 8595 USB keyboard controller chip.
+
+This keyboard has the same quirk for its rfkill / airplane mode hotkey as
+other keyboards with the ITE 8595 chip, it only sends a single release
+event when pressed and released, it never sends a press event.
+
+This commit adds this keyboards USB id to the hid-ite id-table, fixing
+the rfkill key not working on this keyboard.

+Subject: phy: cpcap-usb: Prevent USB line glitches from waking up modem
+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit 63078b6ba09e842f09df052c5728857389fddcd2 ]
+
+The micro-USB connector on Motorola Mapphone devices can be muxed between
+the SoC and the mdm6600 modem. But even when used for the SoC, configuring
+the PHY with ID pin grounded will wake up the modem from idle state. Looks
+like the issue is probably caused by line glitches.
+
+We can prevent the glitches by using a previously unknown mode of the
+GPIO mux to prevent the USB lines from being connected to the moden while
+configuring the USB PHY, and enable the USB lines after configuring the
+PHY.
+
+Note that this only prevents waking up mdm6600 as regular USB A-host mode,
+and does not help when connected to a lapdock. The lapdock specific issue
+still needs to be debugged separately.

+Subject: spi: spi-dw: Add lock protect dw_spi rx/tx to prevent concurrent
+ calls
+
+From: wuxu.wu <wuxu.wu@huawei.com>
+
+[ Upstream commit 19b61392c5a852b4e8a0bf35aecb969983c5932d ]
+
+dw_spi_irq() and dw_spi_transfer_one concurrent calls.
+
+I find a panic in dw_writer(): txw = *(u8 *)(dws->tx), when dw->tx==null,
+dw->len==4, and dw->tx_end==1.
+
+When tpm driver's message overtime dw_spi_irq() and dw_spi_transfer_one
+may concurrent visit dw_spi, so I think dw_spi structure lack of protection.
+
+Otherwise dw_spi_transfer_one set dw rx/tx buffer and then open irq,
+store dw rx/tx instructions and other cores handle irq load dw rx/tx
+instructions may out of order.
