Trusty update to 3.16.7-ckt27 stable release

[Luis Henriques]

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The 3.16.7-ckt27 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://kernel.ubuntu.com/ubuntu/linux.git

    TEST CASE: TBD

       The following patches from the 3.16.7-ckt27 stable release shall be applied:

ipv4: Don't do expensive useless work during inetdev destroy.
Input: powermate - fix oops with malicious USB descriptors
USB: iowarrior: fix oops with malicious USB descriptors
ALSA: usb-audio: Fix NULL dereference in create_fixed_stream_quirk()
ALSA: usb-audio: Add sanity checks for endpoint accesses
include/linux/poison.h: fix LIST_POISON{1,2} offset
cpu: Defer smpboot kthread unparking until CPU known to scheduler
ipr: Fix out-of-bounds null overwrite
ipr: Fix regression when loading firmware
Input: ati_remote2 - fix crashes on detecting device with invalid descriptor
USB: cdc-acm: more sanity checking
ceph: fix request time stamp encoding
cpu: Provide smpboot_thread_init() on !CONFIG_SMP kernels as well
x86/iopl/64: Properly context-switch IOPL on Xen PV
staging: comedi: ni_tiocmd: change mistaken use of start_src for start_arg
drm/radeon: hold reference to fences in radeon_sa_bo_new (3.17 and older)
Drivers: hv: vmbus: prevent cpu offlining on newer hypervisors
