Bug Description

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 4.4.87 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

    TEST CASE: TBD

The following patches from the 4.4.87 stable release shall be applied:
* irqchip: mips-gic: SYNC after enabling GIC region
* i2c: ismt: Don't duplicate the receive length for block reads
* i2c: ismt: Return EMSGSIZE for block reads with bogus length
* ceph: fix readpage from fscache
* cpumask: fix spurious cpumask_of_node() on non-NUMA multi-node configs
* cpuset: Fix incorrect memory_pressure control file mapping
* alpha: uapi: Add support for __SANE_USERSPACE_TYPES__
* CIFS: Fix maximum SMB2 header size
* CIFS: remove endian related sparse warning
* wl1251: add a missing spin_lock_init()
* xfrm: policy: check policy direction value
* drm/ttm: Fix accounting error when fail to get pages for pool
* kvm: arm/arm64: Fix race in resetting stage2 PGD
* kvm: arm/arm64: Force reading uncached stage2 PGD
* epoll: fix race between ep_poll_callback(POLLFREE) and
  ep_free()/ep_remove()
* crypto: algif_skcipher - only call put_page on referenced and used pages
* Linux 4.4.87
