Merge branch 'linux-linaro-lsk-v4.4' into linux-linaro-lsk-v4.4-android

Conflicts:
* arch/arm64/include/asm/assembler.h
    Pick changes from AOSP Change-Id: I450594dc311b09b6b832b707a9abb357608cc6e4
    ("UPSTREAM: arm64: include alternative handling in dcache_by_line_op").

* drivers/android/binder.c
    Pick changes from LTS commit 14f09e8e7cd8 ("ANDROID: binder: Add strong ref checks"),
    instead of AOSP Change-Id: I66c15b066808f28bd27bfe50fd0e03ff45a09fca
    ("ANDROID: binder: Add strong ref checks").

* drivers/usb/gadget/function/u_ether.c
    Refactor throttling of highspeed IRQ logic in AOSP by adding
    a check for last queue request as intended by LTS commit
    660c04e8f174 ("usb: gadget: function: u_ether: don't starve tx request queue").
    Fixes AOSP Change-Id: I26515bfd9bbc8f7af38be7835692143f7093118a
    ("USB: gadget: u_ether: Fix data stall issue in RNDIS tethering mode").
