  updated to 4.4.126 to receive various security and bugfixes.

  The following security bugs were fixed:

  - CVE-2018-1091: In the flush_tmregs_to_thread function in
  arch/powerpc/kernel/ptrace.c, a guest kernel crash can be triggered from
  unprivileged userspace during a core dump on a POWER host due to a
  missing processor feature check and an erroneous use of transactional
  memory (TM) instructions in the core dump path, leading to a denial of
  service (bnc#1087231).

  - CVE-2018-8043: The unimac_mdio_probe function in
  drivers/net/phy/mdio-bcm-unimac.c did not validate certain resource
  availability, which allowed local users to cause a denial of service
  (NULL pointer dereference) (bnc#1084829).

  - CVE-2018-7740: The resv_map_release function in mm/hugetlb.c allowed
  local users to cause a denial of service (BUG) via a crafted application
  that made mmap system calls and has a large pgoff argument to the
  remap_file_pages system call (bnc#1084353).


  The following non-security bugs were fixed:

  - acpica: Add header support for TPM2 table changes (bsc#1084452).

  - acpica: Add support for new SRAT subtable (bsc#1085981).

  - acpica: iasl: Update to IORT SMMUv3 disassembling (bsc#1085981).

  - acpi/IORT: numa: Add numa node mapping for smmuv3 devices (bsc#1085981).

  - acpi, numa: fix pxm to online numa node associations (bnc#1012382).

  - acpi / PMIC: xpower: Fix power_table addresses (bnc#1012382).

  - acpi/processor: Fix error handling in __acpi_processor_start()
  (bnc#1012382).

  - acpi/processor: Replace racy task affinity logic (bnc#1012382).

  - agp/intel: Flush all chipset writes after updating the GGTT
  (bnc#1012382).

  - ahci: Add pci-id for the Highpoint Rocketraid 644L card (bnc#1012382).

  - alsa: aloop: Fix access to not-yet-ready substream via cable
  (bnc#1012382).

  - alsa: aloop: Sync stale timer before release (bnc#1012382).

  - alsa: firewire-digi00x: handle all MIDI messages on streaming packets
  (bnc#1012382).

  - alsa: hda: Add a power_save blacklist (bnc#1012382).

  - alsa: hda: add dock and led support for HP EliteBook 820 G3
  (bnc#1012382).

  - alsa: hda: add dock and led support for HP ProBook 640 G2 (bnc#1012382).

  - alsa: hda/realtek - Always immediately update mute LED with pin VREF
  (bnc#1012382).

  - alsa: hda/realtek - Fix dock line-out volume on Dell Precision 7520
  (bnc#1012382).

  - alsa: hda/realtek - Fix speaker no sound after system resume
  (bsc#1031717).

  - alsa: hda - Revert power_save option default value (git-fixes).

  - alsa: pcm: Fix UAF in snd_pcm_oss_get_formats() (bnc#1012382) ...
