I'm announcing the release of the 4.14.315 kernel. All users of the 4.14 kernel series must upgrade. The updated 4.14.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.14.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 2 arch/arm/boot/dts/exynos4412-itop-elite.dts | 2 arch/arm/boot/dts/s5pv210.dtsi | 2 arch/arm64/include/asm/debug-monitors.h | 1 arch/arm64/kernel/debug-monitors.c | 5 arch/arm64/kernel/kgdb.c | 2 arch/ia64/mm/contig.c | 2 arch/mips/fw/lib/cmdline.c | 2 arch/parisc/kernel/real2.S | 5 arch/powerpc/kernel/rtas.c | 2 arch/powerpc/platforms/512x/clock-commonclk.c | 2 arch/powerpc/platforms/embedded6xx/flipper-pic.c | 2 arch/powerpc/platforms/embedded6xx/hlwd-pic.c | 2 arch/powerpc/platforms/embedded6xx/wii.c | 4 arch/powerpc/sysdev/tsi108_pci.c | 5 arch/sh/kernel/cpu/sh4/sq.c | 2 arch/sh/kernel/nmi_debug.c | 4 arch/sh/math-emu/sfp-util.h | 4 arch/x86/kernel/apic/apic.c | 5 arch/x86/kernel/apic/io_apic.c | 14 - drivers/block/drbd/drbd_receiver.c | 2 drivers/bluetooth/btsdio.c | 1 drivers/clk/clk-conf.c | 12 - drivers/clk/rockchip/clk-rk3399.c | 2 drivers/dma/at_xdmac.c | 5 drivers/gpu/drm/drm_probe_helper.c | 5 drivers/gpu/drm/rockchip/rockchip_drm_gem.c | 3 drivers/gpu/drm/vgem/vgem_fence.c | 1 drivers/hid/wacom_wac.c | 12 - drivers/i2c/busses/i2c-omap.c | 2 drivers/iio/adc/palmas_gpadc.c | 2 drivers/infiniband/hw/hfi1/mmu_rb.c | 13 - drivers/infiniband/sw/rdmavt/qp.c | 2 drivers/macintosh/Kconfig | 1 drivers/macintosh/windfarm_smu_sat.c | 1 drivers/md/dm-flakey.c | 4 drivers/md/dm-integrity.c | 8 drivers/md/dm-ioctl.c | 7 drivers/md/raid10.c | 23 + drivers/media/pci/dm1105/dm1105.c | 1 drivers/media/pci/ttpci/av7110_av.c | 4 drivers/media/platform/sti/bdisp/bdisp-v4l2.c | 2 drivers/mtd/ubi/eba.c | 19 + drivers/net/ethernet/amd/nmclan_cs.c | 2 drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c | 23 + drivers/net/wireless/ath/ath5k/eeprom.c | 2 drivers/net/wireless/ath/ath6kl/bmi.c | 2 drivers/net/wireless/ath/ath6kl/htc_pipe.c | 4 drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c | 5 drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c | 10 drivers/net/wireless/intel/iwlwifi/pcie/trans.c | 3 drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_8192e.c | 1 drivers/of/device.c | 7 drivers/phy/tegra/xusb.c | 2 drivers/power/supply/generic-adc-battery.c | 3 drivers/s390/block/dasd.c | 2 drivers/scsi/megaraid.c | 1 drivers/spi/spi-fsl-spi.c | 12 - drivers/spmi/spmi.c | 3 drivers/staging/iio/resolver/ad2s1210.c | 2 drivers/staging/rtl8192e/rtl8192e/rtl_core.c | 1 drivers/target/iscsi/iscsi_target.c | 16 - drivers/tty/serial/8250/8250.h | 12 + drivers/tty/serial/8250/8250_port.c | 16 + drivers/tty/serial/fsl_lpuart.c | 2 drivers/tty/tty_io.c | 4 drivers/tty/tty_ioctl.c | 45 ++- drivers/usb/chipidea/core.c | 2 drivers/usb/dwc3/core.c | 1 drivers/usb/serial/option.c | 6 fs/btrfs/ctree.c | 32 ++ fs/btrfs/ioctl.c | 5 fs/btrfs/print-tree.c | 6 fs/cifs/smb2ops.c | 2 fs/ext4/inline.c | 14 + fs/ext4/mballoc.c | 6 fs/ext4/super.c | 19 + fs/ext4/xattr.c | 5 fs/fs-writeback.c | 2 fs/nfs/nfs4state.c | 4 fs/nilfs2/bmap.c | 16 + fs/nilfs2/segment.c | 5 fs/pstore/pmsg.c | 7 fs/reiserfs/xattr_security.c | 8 fs/ubifs/dir.c | 1 fs/ubifs/tnc.c | 9 include/linux/printk.h | 19 + include/linux/sunrpc/sched.h | 3 include/linux/tty.h | 2 include/linux/vt_buffer.h | 2 include/net/netfilter/nf_tables.h | 30 ++ include/net/scm.h | 13 + include/uapi/linux/btrfs.h | 1 include/uapi/linux/const.h | 2 kernel/events/core.c | 4 kernel/trace/ring_buffer.c | 4 mm/page_alloc.c | 16 + net/8021q/vlan_dev.c | 2 net/bluetooth/hci_sock.c | 9 net/core/skbuff.c | 3 net/ipv4/ip_output.c | 16 + net/ipv6/sit.c | 8 net/netfilter/nf_tables_api.c | 139 ++++++++---- net/netfilter/nft_dynset.c | 22 + net/netfilter/nft_immediate.c | 6 net/netfilter/nft_lookup.c | 21 + net/netfilter/nft_objref.c | 21 + net/netfilter/nft_set_hash.c | 2 net/packet/af_packet.c | 20 - net/packet/diag.c | 4 net/packet/internal.h | 26 +- net/sched/act_mirred.c | 2 net/sunrpc/clnt.c | 3 net/sunrpc/sched.c | 1 security/selinux/Makefile | 4 sound/usb/caiaq/input.c | 1 tools/perf/bench/bench.h | 4 tools/perf/bench/futex-hash.c | 12 - tools/perf/bench/futex-lock-pi.c | 11 tools/perf/builtin-sched.c | 2 tools/perf/pmu-events/arch/powerpc/power9/other.json | 4 tools/perf/pmu-events/arch/powerpc/power9/pipeline.json | 2 tools/perf/util/auxtrace.c | 5 tools/perf/util/sort.c | 3 tools/perf/util/symbol-elf.c | 2 125 files changed, 705 insertions(+), 277 deletions(-) Adrian Hunter (1): perf auxtrace: Fix address filter entire kernel size Alexander Mikhalitsyn (1): scm: fix MSG_CTRUNC setting condition for SO_PASSSEC Alexey V.

[PATCH v8 2/2] EDAC/qcom: Get rid of hardcoded register offsets

by Manivannan Sadhasivam

The LLCC EDAC register offsets varies between each SoC. Hardcoding the register offsets won't work and will often result in crash due to accessing the wrong locations. Hence, get the register offsets from the LLCC driver matching the individual SoCs.

[PATCH v2 2/9] PCI: pciehp: Use RMW accessors for changing LNKCTL

[PATCH v2 1/9] PCI: Add locking to RMW PCI Express Capability Register accessors

by Ilpo Järvinen

Many places in the kernel write the Link Control and Root Control PCI Express Capability Registers without proper concurrency control and this could result in losing the changes one of the writers intended to make. Add pcie_cap_lock spinlock into the struct pci_dev and use it to protect bit changes made in the RMW capability accessors. Protect only a selected set of registers by differentiating the RMW accessor internally to locked/unlocked variants using a wrapper which has the same signature as pcie_capability_clear_and_set_word(). As the Capability Register (pos) given to the wrapper is always a constant, the compiler should be able to simplify all the dead-code away. The RMW locking is only added to pcie_capability_clear_and_set_word() because so far only the Link Control Register (ASPM, hotplug, various drivers) and the Root Control Register (AER & PME) require RMW locking. Fixes: c7f486567c1d ("PCI PM: PCIe PME root port service driver") Fixes: f12eb72a268b ("PCI/ASPM: Use PCI Express Capability accessors") Fixes: 7d715a6c1ae5 ("PCI: add PCI Express ASPM support") Fixes: affa48de8417 ("staging/rdma/hfi1: Add support for enabling/disabling PCIe ASPM") Fixes: 849a9366cba9 ("misc: rtsx: Add support new chip rts5228 mmc: rtsx: Add support MMC_CAP2_NO_MMC") Fixes: 3d1e7aa80d1c ("misc: rtsx: Use pcie_capability_clear_and_set_word() for PCI_EXP_LNKCTL") Fixes: c0e5f4e73a71 ("misc: rtsx: Add support for RTS5261") Fixes: 3df4fce739e2 ("misc: rtsx: separate aspm mode into MODE_REG and MODE_CFG") Fixes: 121e9c6b5c4c ("misc: rtsx: modify and fix init_hw function") Fixes: 19f3bd548f27 ("mfd: rtsx: Remove LCTLR defination") Fixes: 773ccdfd9cc6 ("mfd: rtsx: Read vendor setting from config space") Fixes: 8275b77a1513 ("mfd: rts5249: Add support for RTS5250S power saving") Fixes: 5da4e04ae480 ("misc: rtsx: Add support for RTS5260") Fixes: 0f49bfbd0f2e ("tg3: Use PCI Express Capability accessors") Fixes: 5e7dfd0fb94a ("tg3: Prevent corruption at 10 / 100Mbps w CLKREQ") Fixes: b726e493e8dc ("r8169: sync existing 8168 device hardware start sequences with vendor driver") Fixes: e6de30d63eb1 ("r8169: more 8168dp support.")

[PATCH v2 6/9] net/mlx5: Use RMW accessors for changing LNKCTL

by Ilpo Järvinen

Don't assume that only the driver would be accessing LNKCTL of the upstream bridge. ASPM policy changes can trigger write to LNKCTL outside of driver's control. Use RMW capability accessors which do proper locking to avoid losing concurrent updates to the register value.

[PATCH v2 7/9] wifi: ath11k: Use RMW accessors for changing LNKCTL

by Ilpo Järvinen

Don't assume that only the driver would be accessing LNKCTL. ASPM policy changes can trigger write to LNKCTL outside of driver's control. Use RMW capability accessors which do proper locking to avoid losing concurrent updates to the register value. On restore, clear the ASPMC field properly.
