Public bug reported:

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 following upstream
       stable patches should be included in the Ubuntu kernel:

       v4.4.247 upstream stable release
       from git://git.kernel.org/

btrfs: tree-checker: Enhance chunk checker to validate chunk profile
btrfs: inode: Verify inode mode to avoid NULL pointer dereference
HID: cypress: Support Varmilo Keyboards' media hotkeys
Input: i8042 - allow insmod to succeed on devices without an i8042 controller
HID: hid-sensor-hub: Fix issue with devices with no report ID
x86/xen: don't unbind uninitialized lock_kicker_irq
proc: don't allow async path resolution of /proc/self components
dmaengine: pl330: _prep_dma_memcpy: Fix wrong burst size
scsi: libiscsi: Fix NOP race condition
scsi: target: iscsi: Fix cmd abort fabric stop race
scsi: ufs: Fix race between shutdown and runtime resume flow
bnxt_en: fix error return code in bnxt_init_board()
video: hyperv_fb: Fix the cache type when mapping the VRAM
bnxt_en: Release PCI regions when DMA mask setup fails during probe.
IB/mthca: fix return value of error branch in mthca_init_cq()
nfc: s3fwrn5: use signed integer for parsing GPIO numbers
efivarfs: revert "fix memory leak in efivarfs_create()"
perf probe: Fix to die_entrypc() returns error correctly
USB: core: Change %pK for __user pointers to %px
x86/speculation: Fix prctl() when spectre_v2_user={seccomp,prctl},ibpb
USB: core: add endpoint-blacklist quirk
USB: core: Fix regression in Hercules audio card
btrfs: fix lockdep splat when reading qgroup config on mount
Linux 4.4.247
UBUNTU: upstream stable to v4.4.247
