Geert Uytterhoeven 24f1c13fa5 dt-bindings: thermal: rcar-gen3-thermal: All variants use 3 interrupts
RZ/G2M also has 3 interrupts routed to the TSC, but the list was not
updated to reflect this.

Just drop the list, as this is the case for this TSC variant in all
R-Car Gen3 and RZ/G2 SoCs.

Matthias Brugger d56c19d07e thermal: bcm2835: enable hwmon explicitly
By defaul of-based thermal driver do not enable hwmon.
This patch does this explicitly, so that the temperature can be read

Richard Zhu 75cb8d20c1 PCI: imx: Enable MSI from downstream components
The MSI Enable bit in the MSI Capability (PCIe r4.0, sec 7.7.1.2) controls
whether a Function can request service using MSI.

i.MX6 Root Ports implement the MSI Capability and may use MSI to request
service for events like PME, hotplug, AER, etc.  In addition, on i.MX6, the
MSI Enable bit controls delivery of MSI interrupts from components below
the Root Port.

Prior to f3fdfc4ac3 ("PCI: Remove host driver Kconfig selection of
CONFIG_PCIEPORTBUS"), enabling CONFIG_PCI_IMX6 automatically also enabled
CONFIG_PCIEPORTBUS, and when portdrv claimed the Root Ports, it set the MSI
Enable bit so it could use PME, hotplug, AER, etc.  As a side effect, that
also enabled delivery of MSI interrupts from downstream components.

The imx6q-pcie driver itself does not depend on portdrv, so set MSI Enable
in imx6q-pcie so MSI from downstream components works even if nobody uses
MSI for the Root Port events.

Including (in no particular order):
 
 	- Page table code for AMD IOMMU now supports large pages where
 	  smaller page-sizes were mapped before. VFIO had to work around
 	  that in the past and I included a patch to remove it (acked by
 	  Alex Williamson)
 
 	- Patches to unmodularize a couple of IOMMU drivers that would
 	  never work as modules anyway.
 
 	- Work to unify the the iommu-related pointers in
 	  'struct device' into one pointer. This work is not finished
 	  yet, but will probably be in the next cycle.
 
 	- NUMA aware allocation in iommu-dma code
 
 	- Support for r8a774a1 and r8a774c0 in the Renesas IOMMU driver
 
 	- Scalable mode support for the Intel VT-d driver
 
 	- PM runtime improvements for the ARM-SMMU driver
 
 	- Support for the QCOM-SMMUv2 IOMMU hardware from Qualcom
 
 	- Various smaller fixes and improvements

Linus Torvalds fcf010449e kgdb patches for 4.20-rc1
Mostly clean ups although whilst Doug's was chasing down a odd
 lockdep warning he also did some work to improved debugger resilience
 when some CPUs fail to respond to the round up request.
 
 The main changes are:
 
  * Fixing a lockdep warning on architectures that cannot use an NMI for
    the round up plus related changes to make CPU round up and all CPU
    backtrace more resilient.
 
  * Constify the arch ops tables
 
  * A couple of other small clean ups
 
 Two of the three patchsets here include changes that spill over into
 arch/.  Changes in the arch space are relatively narrow in scope
 (and directly related to kgdb). Didn't get comprehensive acks but
 all impacted maintainers were Cc:ed in good time.

Willem de Bruijn cb9f1b7838 ip: validate header length on virtual device xmit
KMSAN detected read beyond end of buffer in vti and sit devices when
passing truncated packets with PF_PACKET. The issue affects additional
ip tunnel devices.

Extend commit 76c0ddd8c3 ("ip6_tunnel: be careful when accessing the
inner header") and commit ccfec9e5cb ("ip_tunnel: be careful when
accessing the inner header").

Move the check to a separate helper and call at the start of each
ndo_start_xmit function in net/ipv4 and net/ipv6.

Minor changes:
- convert dev_kfree_skb to kfree_skb on error path,
  as dev_kfree_skb calls consume_skb which is not for error paths.
- use pskb_network_may_pull even though that is pedantic here,
  as the same as pskb_may_pull for devices without llheaders.
- do not cache ipv6 hdrs if used only once
  (unsafe across pskb_may_pull, was more relevant to earlier patch)

Takashi Iwai 3e9ad24b0e ALSA: hda - Revert DSP detection on legacy HD-audio driver
This essentially reverts the commits
  c337104b1a ("ALSA: HD-Audio: SKL+: abort probe if DSP is present
  and Skylake driver selected")
and
  d82b51c855 ("ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+
  driver selection")
for the path of legacy HD-audio controller (snd-hda-intel).

The automatic DSP detection and skip of binding with the legacy driver
caused regressions on several machines like Dell XPS13.  They give the
PCI class 0x40380 indicating the availability of DSP while they don't
work with ASoC SKL driver (yet).

As the support of ASoC driver for such devices isn't available, it's
better to revert the whole DSP-detection-and-skip behavior of the
legacy driver, so that we can get the old good driver working on such
devices.

The pci_binding option for ASoC SKL driver is still kept so that it
can work without blacklisting.

Deepa Dinamani 3a0ed3e961 sock: Make sock->sk_stamp thread-safe
Al Viro mentioned (Message-ID
<20170626041334.GZ10672@ZenIV.linux.org.uk>)
that there is probably a race condition
lurking in accesses of sk_stamp on 32-bit machines.

sock->sk_stamp is of type ktime_t which is always an s64.
On a 32 bit architecture, we might run into situations of
unsafe access as the access to the field becomes non atomic.

Use seqlocks for synchronization.
This allows us to avoid using spinlocks for readers as
readers do not need mutual exclusion.

Another approach to solve this is to require sk_lock for all
modifications of the timestamps. The current approach allows
for timestamps to have their own lock: sk_stamp_lock.
This allows for the patch to not compete with already
existing critical sections, and side effects are limited
to the paths in the patch.

The addition of the new field maintains the data locality
optimizations from
commit 9115e8cd2a ("net: reorganize struct sock for better data
locality")

Note that all the instances of the sk_stamp accesses
are either through the ioctl or the syscall recvmsg.

Linus Torvalds e1ef035d27 ARM: SoC defconfig updates
Most changes here are to enable new drivers and platforms in the various
 configs that affect them. Most of these have been covered and described
 in the other branches, we mostly keep defconfig separate to avoid
 conflicts between SoC/dt/driver updates that they otherwise would be
 grouped with.
 
 One thing worth mentioning here is that OMAP changes from using their
 own UART driver, to 8250, for the multi_v7_defconfig shared config on
 32-bit. This means that the console is now named ttyS* instead of ttyO*.
 This change was already done for omap2_defconfig a while back, so most
 users of these configs have either already updated, or can easily follow
 the same patterns as they did at that time. This makes platform support
 slightly easier for distros, since they no longer need to keep track of
 a separate console prefix for these platforms.

Linus Torvalds b7badd1d7a ARM: Device-tree updates
As usual, this is where the bulk of our changes end up landing each
 merge window.
 
 The individual updates are too many to enumerate, many many platforms
 have seen additions of device descriptions such that they are
 functionally more complete (in fact, this is often the bulk of updates
 we see).
 
 Instead I've mostly focused on highlighting the new platforms below as
 they are introduced. Sometimes the introduction is of mostly a fragment,
 that later gets filled in on later releases, and in some cases it's
 near-complete platform support. The latter is more common for derivative
 platforms that already has similar support in-tree.
 
 Two SoCs are slight outliers from the usual range of additions. Allwinner
 support for F1C100s, a quite old SoC (ARMv5-based) shipping in the
 Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A,
 a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at
 infrastructure/networking.
 
 TI updates stick out in the diff stats too, in particular because they
 have moved the description of their L4 on-chip interconnect to devicetree,
 which opens up for removal of even more of their platform-specific
 'hwmod' description tables over the next few releases.
 
 SoCs:
  - Qualcomm QCS404 (4x Cortex-A53)
  - Allwinner T3 (rebranded R40) and f1c100s (armv5)
  - NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4)
  - NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72)
 
 New platforms:
  - Rockchip: Gru Scarlet (RK3188 Tablet)
  - Amlogic: Phicomm N1 (S905D), Libretech S805-AC
  - Broadcom: Linksys EA6500 v2 Wi-Fi router (BCM4708)
  - Qualcomm: QCS404 base platform and EVB
  - Qualcomm: Remove of Arrow SD600
  - PXA: First PXA3xx DT board: Raumfeld
  - Aspeed: Facebook Backpack-CMM BMC
  - Renesas iWave G20D-Q7 (RZ/G1N)
  - Allwinner t3-cqa3t-bv3 (T3/R40) and Lichee Pi Nano (F1C100s)

Pull ARM Device-tree updates from Olof Johansson:
 "As usual, this is where the bulk of our changes end up landing each
  merge window.

  The individual updates are too many to enumerate, many many platforms
  have seen additions of device descriptions such that they are
  functionally more complete (in fact, this is often the bulk of updates
  we see).

  Instead I've mostly focused on highlighting the new platforms below as
  they are introduced. Sometimes the introduction is of mostly a
  fragment, that later gets filled in on later releases, and in some
  cases it's near-complete platform support. The latter is more common
  for derivative platforms that already has similar support in-tree.

  Two SoCs are slight outliers from the usual range of additions.
  Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping
  in the Lychee Pi Nano platform. At the other end is NXP Layerscape
  LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O
  aimed at infrastructure/networking.

  TI updates stick out in the diff stats too, in particular because they
  have moved the description of their L4 on-chip interconnect to
  devicetree, which opens up for removal of even more of their
  platform-specific 'hwmod' description tables over the next few
  releases.

  SoCs:
   - Qualcomm QCS404 (4x Cortex-A53)
   - Allwinner T3 (rebranded R40) and f1c100s (armv5)
   - NXP i.MX7ULP (1x Cortex-A7 + 1x Cortex-M4)
   - NXP LS1028A (2x Cortex-A72), LX2160A (16x Cortex-A72)

  New platforms:
   - Rockchip: Gru Scarlet (RK3188 Tablet)
   - Amlogic: Phicomm N1 (S905D), Libretech S805-AC
   - Broadcom: Linksys EA6500 v2 Wi-Fi router (BCM4708)
   - Qualcomm: QCS404 base platform and EVB
   - Qualcomm: Remove of Arrow SD600
   - PXA: First PXA3xx DT board: Raumfeld
   - Aspeed: Facebook Backpack-CMM BMC
   - Renesas iWave G20D-Q7 (RZ/G1N)

Linus Torvalds 0922275ef1 ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms,
 but also a few more things:
 
 New SoC support this release:
  - NXP/Freescale i.MX7ULP (1x Cortex-A7, Cortex-M4, graphics, etc)
  - Allwinner F1C100, older platform with an ARM926-EJS (ARMv5) core
 
 Cleanups of various platforms:
  - OMAP1 ams-delta does some GPIO cleanups
  - Davinci removes of at24 platform data
  - Samsung cleans up old wakeup, PM debug and secondary core boot code
  - Renesas moves around config options and PM code to drivers/soc for
    sharing with 64-bit and more consistency
  - i.MX, Broadcom and SoCFPGA all have tweaks to lowlevel debug console setups
  - SoCFPGA adds explicit selection of ARM errata and removes some unused code
 
 This tag also contains a few patches that I had queued up as fixes for
 4.20 but didn't send in before the release.

Tyrel Datwyler 756af9c642 ibmveth: fix DMA unmap error in ibmveth_xmit_start error path
Commit 33a48ab105 ("ibmveth: Fix DMA unmap error") fixed an issue in the
normal code path of ibmveth_xmit_start() that was originally introduced by
Commit 6e8ab30ec6 ("ibmveth: Add scatter-gather support"). This original
fix missed the error path where dma_unmap_page is wrongly called on the
header portion in descs[0] which was mapped with dma_map_single. As a
result a failure to DMA map any of the frags results in a dmesg warning
when CONFIG_DMA_API_DEBUG is enabled.

- It contains the initial device tree support for i.MX8MQ - the first
    ARM64 i.MX processor.  It features a quad Cortex-A53 core that
    operates at speeds of up to 1.3 GHz, a Cortex-M4 core for
    low-power processing, a DRAM controller that supports 32-bit/16-bit
    LPDDR4/DDR4/DDR3L memory, and hardware acceleration for 4K video
    playback.
  - A couple of patches from Baruch that add watchdog device for i.MX8MQ
    enable it for imx8mq-evk board.
