+Subject: [PATCH] ath9k: fix max noise floor threshold
+
+From: Rajkumar Manoharan <rmanohar@qca.qualcomm.com>
+
+commit 2ee0a07028d2cde6e131b73f029dae2b93c50f3a upstream.
+
+Currently the maximum noise floor limit is set as too high (-60dB). The
+assumption of having a higher threshold limit is that it would help
+de-sensitize the receiver (reduce phy errors) from continuous
+interference. But when we have a bursty interference where there are
+collisions and then free air time and if the receiver is desensitized too
+much, it will miss the normal packets too. Lets make use of chips
+specific min, nom and max limits always. This patch helps to improve the
+connection stability in congested networks.

+Subject: fcaps: clear the same personality flags as suid when fcaps are used
+
+From: Eric Paris <eparis@redhat.com>
+
+commit d52fc5dde171f030170a6cb78034d166b13c9445 upstream.
+
+If a process increases permissions using fcaps all of the dangerous
+personality flags which are cleared for suid apps should also be cleared.
+Thus programs given priviledge with fcaps will continue to have address space
+randomization enabled even if the parent tried to disable it to make it
+easier to attack.

+Subject: serial: PL011: clear pending interrupts
+
+From: Linus Walleij <linus.walleij@linaro.org>
+
+commit 9b96fbacda34079dea0638ee1e92c56286f6114a upstream.
+
+Chanho Min reported that when the boot loader transfers
+control to the kernel, there may be pending interrupts
+causing the UART to lock up in an eternal loop trying to
+pick tokens from the FIFO (since the RX interrupt flag
+indicates there are tokens) while in practice there are
+no tokens - in fact there is only a pending IRQ flag.
+
+This patch address the issue with a combination of two
+patches suggested by Russell King that clears and mask
+all interrupts at probe() and clears any pending error
+and RX interrupts at port startup time.
+
+We suspect the spurious interrupts are a side-effect of
+switching the UART from FIFO to non-FIFO mode.

+Subject: xHCI: add XHCI_RESET_ON_RESUME quirk for VIA xHCI host
+
+From: Elric Fu <elricfu1@gmail.com>
+
+commit 457a4f61f9bfc3ae76e5b49f30f25d86bb696f67 upstream.
+
+The suspend operation of VIA xHCI host have some issues and
+hibernate operation works fine, so The XHCI_RESET_ON_RESUME
+quirk is added for it.
+
+This patch should base on "xHCI: Don't write zeroed pointer
+to xHC registers" that is released by Sarah. Otherwise, the
+host system error will ocurr in the hibernate operation
+process.
+
+This should be backported to stable kernels as old as 2.6.37,
+that contain the commit c877b3b2ad5cb9d4fe523c5496185cc328ff3ae9
+"xhci: Add reset on resume quirk for asrock p67 host".
