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-2018-7740: 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).
- 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-2017-18257: The __get_data_block function in fs/f2fs/data.c allowed
 local users to cause a denial of service (integer overflow and loop) via
 crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP
 ioctl. (bnc#1088241)
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel
 function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious
 NCPFS servers to crash the kernel or execute code (bnc#1086162).
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).
- add mainline tag to various patches to be able to get further work done
- af_iucv: enable control sends in case of SEND_SHUTDOWN (bnc#1085507,
 LTC#165135).
- 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).
