The biggest change here is the updates to kprobes
Back in January I posted patches to create function based events. These were
the events that you suggested I make to allow developers to easily create
events in code where no trace event exists. After posting those changes for
review, it was suggested that we implement this instead with kprobes.
The problem with kprobes is that the interface is too complex and needs to
be simplified. Masami Hiramatsu posted patches in March and I've been
playing with them a bit. There's been a bit of clean up in the kprobe code
that was inspired by the function based event patches, and a couple of
enhancements to the kprobe event interface.
- If the arch supports it (we added support for x86), you can place a
kprobe event at the start of a function and use $arg1, $arg2, etc
to reference the arguments of a function. (Before you needed to know
what register or where on the stack the argument was).
- The second is a way to see array of events. For example, if you reference
a mac address, you can add:
echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events
And this will produce:
mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec}
Other changes include
- Exporting trace_dump_stack to modules
- Have the stack tracer trace the entire stack (stop trying to remove
tracing itself, as we keep removing too much).
- Added support for SDT in uprobes

remoteproc updates for v4.20
This contains a series of patches that reworks the memory carveout handling in remoteproc, in order to allow this to be reused for statically allocated memory regions to be used for e.g. firmware. It adds support for audio DSP (both TZ-assisted and non-TZ assisted) and compute DSP on Qualcomm SDM845, TZ-assisted audio DSP, compute DSP and WiFi processor on Qualcomm QCS404 and through some renaming of the drivers cleans up the naming situation. Finally support for custom coreudmp segment handlers is added and is used in the Qualcomm modem remoteproc driver to gather memory dumps of the firmware. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAlvXlhMbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FvvUP/j5M7fvB1kJnd6NUJ1Hz CKTw05eYeC4Z9d6nBIso6jcYbf6QfBwtBmdEPfa8Yzhc+Mkr91dR85ylzjd1+PXm qcCEOrofMMHQ2CSPO0dfdii4zvQRdo2CvMShJqdc/PUo0G4QPQR8Pdb6fLW5S4uL zb0K0CqS8KBzY382r6QyV5riv+8nsuTKLWTzPHL/mmXD0aW5YCVgxG56DScFJVu3 HD9YzbsECzIBuB0k1UufdYxb2FkRy2pOWttiKDQAlB2q7AxOwEV/oqWQKpmHVb2k F94zRWlttuMabjtRajDDSqfG8DUse7zpCgakk+oehEZq1WmcVfLKs+asqELBLNc7 J/3N1g2+cE+VQUqBiew6WUR6zgMFMfyqucnp8t0KRgZvpQPxfpiRqynoFxEj8MXl z4lptuk7DMhYphrwWhA+D/Jqc1prMmX7smCDou3b43DFVYZ06c2gI7aO9VPVhT4m SUFhzznTn6FUfnFWzDAuDKt51WaRIFemgvvprsNHrl24rtQhYdel+12U9ySiFq8q Z7Bqb3jNcZ6qHjLy4+6jtnQSZoyf6bbcvF2++85m16i4vElu1X1TQ6HXMmrXpBZ9 z454/jVacZ2vtiAzustBlu86QQZtQhVHenn7j34AWkqIBCF3PiHuZqVfaw0R/pZq 3/HkgfsgudLRu4+qIclHDX+X =mM8w -----END PGP SIGNATURE----- Merge tag 'rproc-v4.20' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This contains a series of patches that reworks the memory carveout handling in remoteproc, in order to allow this to be reused for statically allocated memory regions to be used for e.g. firmware.

ARM: SoC platform updates for 4.20
A couple of platforms change hands in the MAINTAINERS file:
- Linus Walleij lists himself for the ARM Reference platforms:
versatile, vexpress, integrator and realview. He has been the main
contributor for these for a while, and makes it official now.
- Vladimir Zapolskiy takes over the LPC18xx platform from Joachim Eastwood
- Manivannan Sadhasivam becomes a secondary maintainer for the
Actions Semi machines
- Nicolas Ferre lists updates the MAINTAINER listing for the AT91
platform: Ludovic Desroches is now a co-maintainer for the platform, and
several other people (Claudiu Beznea, Cristian Birsan, Eugen Hristev,
Codrin Ciubotariu) take over individual device drivers.
Thanks everyone for working on this, and welcome to the new maintainers!
The "virt" platform on qemy or kvm can now be used in big-endian mode
without additional tricks, thanks to Jason Donenfeld.
Once again, we gain support for another NXP i.MX6 variant, this time
it's the i.MX 6ULZ 32-bit single-core version.
On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
and RZ/G2M (r8a774a1). These are described as microcontrollers on the
manufacturer website, but appear to be rather powerful. The RZ/G2M is
used on the reference board for the CIP Super Long Term Support (SLTS)
Linux Kernels.

ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl" interface
that was a little controversial at first, but the version we merged
solved that by not exposing arbitrary firmware calls to user space.
- The Amlogic Meson platform gains a "canvas" driver that is used
for video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for
their respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in particular
a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem"
device driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

ARM: SoC device tree updates for 4.20
There are close to 800 indivudal changesets in this branch again, which feels like a lot. There are particularly many changes for the NVIDIA Tegra platform this time, in fact more than it has seen in the two years since the v4.9 merge window. Aside from this, it's been fairly normal, with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP. Most of the changes are for adding new features into existing boards, for brevity I'm only mentioning completely new machines and SoCs here. For the first time I think we have (slightly) more new 64-bit hardware than 32-bit: Two boards get added for TI OMAP: Moxa UC-2101 is an industrial computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a minor variation of the motherboards of the GTA04 phone, see https://shop.goldelico.com/wiki.php?page=GTA04A5 Clearfog is a nice little board for quad-core Marvell Armada 8040 network processor, see https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/ Two additional server boards come with the Aspeed baseboard management controllers: Stardragon4800 is an arm64 reference platform made by HXT (based on Qualcomm's server chips), and TiogaPass is an Open Compute mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the BMC. NXP i.MX usually sees a lot of new boards each release. This time there we only add one minor variant: ConnectCore 6UL SBC Pro uses the same SoM design as the ConnectCore 6UL SBC Express added later. However, there is a new chip, the i.MX6ULZ, which is an even smaller variant of the i.MX6ULL, with features removed. There is also support for the reference board design, the i.MX6ULZ 14x14 EVK. A new Raspberry Pi variant gets added, this one is the CM3 compute module based on bcm2837, it was launched in early 2017 but only now added to the kernel, both as 32-bit and as 64-bit files, as we tend to do for Raspberry Pi. On the Allwinner side, everything is again about cheap development boards, usually of the "Fruit Pi" variety. The new ones this time are: Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/ Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/ Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html The last one of these is now a 64-bit version of the earlier Banana Pi M2+ H3, with the same board layout. Similarly, for Rockchips, get get another variant of the 32-bit Asus Tinker board, the model 'S' based on rk3288, and three now boards based on the popular RK3399 chip: ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/ Rock960: https://www.96boards.org/product/rock960/ RockPro64: https://www.pine64.org/?page_id=61454 These are all quite powerful boards with lots of RAM and I/O, and the RK3399 is the same chip used in several Chromebooks. Finally, we get support for the PX30 (aka rk3326) chip, which is based on the low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board is supported. One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based on the MT7622 WiFi router platform, and the first product I've seen with a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370 development board, which are similar to the Hi3660 and Hikey 360 respectively, but add support for an NPU. Amlogic gets initial support for the Meson-G12A chip (S905D2), another quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit side, we gain support for an actual end-user product, the Endless Computers Endless Mini based on Meson8b (S805), see https://endlessos.com/computers/ Qualcomm adds support for their MSM8998 SoC and evaluation platform. This chip is commonly known as the Snapdragon 835, and is used in high-end phones as well as low-end laptops. For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added, but no boards for this one. However, we do add boards for the previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB Starter Kit Pro.

There are particularly many changes for the NVIDIA Tegra platform this time, in fact more than it has seen in the two years since the v4.9 merge window. Aside from this, it's been fairly normal, with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP. Most of the changes are for adding new features into existing boards, for brevity I'm only mentioning completely new machines and SoCs here. For the first time I think we have (slightly) more new 64-bit hardware than 32-bit: Two boards get added for TI OMAP: Moxa UC-2101 is an industrial computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a minor variation of the motherboards of the GTA04 phone, see https://shop.goldelico.com/wiki.php?page=GTA04A5 Clearfog is a nice little board for quad-core Marvell Armada 8040 network processor, see https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/ Two additional server boards come with the Aspeed baseboard management controllers: Stardragon4800 is an arm64 reference platform made by HXT (based on Qualcomm's server chips), and TiogaPass is an Open Compute mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the BMC. NXP i.MX usually sees a lot of new boards each release. This time there we only add one minor variant: ConnectCore 6UL SBC Pro uses the same SoM design as the ConnectCore 6UL SBC Express added later. However, there is a new chip, the i.MX6ULZ, which is an even smaller variant of the i.MX6ULL, with features removed. There is also support for the reference board design, the i.MX6ULZ 14x14 EVK. A new Raspberry Pi variant gets added, this one is the CM3 compute module based on bcm2837, it was launched in early 2017 but only now added to the kernel, both as 32-bit and as 64-bit files, as we tend to do for Raspberry Pi. On the Allwinner side, everything is again about cheap development boards, usually of the "Fruit Pi" variety. The new ones this time are: - Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/ - Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/ - Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts - Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html The last one of these is now a 64-bit version of the earlier Banana Pi M2+ H3, with the same board layout. Similarly, for Rockchips, get get another variant of the 32-bit Asus Tinker board, the model 'S' based on rk3288, and three now boards based on the popular RK3399 chip: - ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/ - Rock960: https://www.96boards.org/product/rock960/ - RockPro64: https://www.pine64.org/?page_id=61454 These are all quite powerful boards with lots of RAM and I/O, and the RK3399 is the same chip used in several Chromebooks. Finally, we get support for the PX30 (aka rk3326) chip, which is based on the low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board is supported. One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based on the MT7622 WiFi router platform, and the first product I've seen with a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370 development board, which are similar to the Hi3660 and Hikey 360 respectively, but add support for an NPU. Amlogic gets initial support for the Meson-G12A chip (S905D2), another quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit side, we gain support for an actual end-user product, the Endless Computers Endless Mini based on Meson8b (S805), see https://endlessos.com/computers/ Qualcomm adds support for their MSM8998 SoC and evaluation platform. This chip is commonly known as the Snapdragon 835, and is used in high-end phones as well as low-end laptops. For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added, but no boards for this one. However, we do add boards for the previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB Starter Kit Pro. While we have lots of DT changes for NVIDIA to update the existing files, the only board that gets added is the Toradex Colibri T20 on Colibri Evaluation Board for the old Tegra2.

Staging/IIO patches for 4.20-rc1
Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.
When merging with your tree, there will be 2 merge conflicts, both files
will be simple to resolve, just delete them :)

mm: don't raise MEMCG_OOM event due to failed high-order allocation
It was reported that on some of our machines containers were restarted
with OOM symptoms without an obvious reason. Despite there were almost no
memory pressure and plenty of page cache, MEMCG_OOM event was raised
occasionally, causing the container management software to think, that OOM
has happened. However, no tasks have been killed.
The following investigation showed that the problem is caused by a failing
attempt to charge a high-order page. In such case, the OOM killer is
never invoked. As shown below, it can happen under conditions, which are
very far from a real OOM: e.g. there is plenty of clean page cache and no
memory pressure.
There is no sense in raising an OOM event in this case, as it might
confuse a user and lead to wrong and excessive actions (e.g. restart the
workload, as in my case).
Let's look at the charging path in try_charge(). If the memory usage is
about memory.max, which is absolutely natural for most memory cgroups, we
try to reclaim some pages. Even if we were able to reclaim enough memory
for the allocation, the following check can fail due to a race with
another concurrent allocation:
if (mem_cgroup_margin(mem_over_limit) >= nr_pages)
goto retry;
For regular pages the following condition will save us from triggering
the OOM:
if (nr_reclaimed && nr_pages <= (1 << PAGE_ALLOC_COSTLY_ORDER))
goto retry;
But for high-order allocation this condition will intentionally fail. The
reason behind is that we'll likely fall to regular pages anyway, so it's
ok and even preferred to return ENOMEM.
In this case the idea of raising MEMCG_OOM looks dubious.
Fix this by moving MEMCG_OOM raising to mem_cgroup_oom() after allocation
order check, so that the event won't be raised for high order allocations.
This change doesn't affect regular pages allocation and charging.

mm: provide kernel parameter to allow disabling page init poisoning
Patch series "Address issues slowing persistent memory initialization", v5. The main thing this patch set achieves is that it allows us to initialize each node worth of persistent memory independently. As a result we reduce page init time by about 2 minutes because instead of taking 30 to 40 seconds per node and going through each node one at a time, we process all 4 nodes in parallel in the case of a 12TB persistent memory setup spread evenly over 4 nodes. This patch (of 3): On systems with a large amount of memory it can take a significant amount of time to initialize all of the page structs with the PAGE_POISON_PATTERN value. I have seen it take over 2 minutes to initialize a system with over 12TB of RAM. In order to work around the issue I had to disable CONFIG_DEBUG_VM and then the boot time returned to something much more reasonable as the arch_add_memory call completed in milliseconds versus seconds. However in doing that I had to disable all of the other VM debugging on the system. In order to work around a kernel that might have CONFIG_DEBUG_VM enabled on a system that has a large amount of memory I have added a new kernel parameter named "vm_debug" that can be set to "-" in order to disable it.

psi: cgroup support
On a system that executes multiple cgrouped jobs and independent workloads, we don't just care about the health of the overall system, but also that of individual jobs, so that we can ensure individual job health, fairness between jobs, or prioritize some jobs over others. This patch implements pressure stall tracking for cgroups. In kernels with CONFIG_PSI=y, cgroup2 groups will have cpu.pressure, memory.pressure, and io.pressure files that track aggregate pressure stall times for only the tasks inside the cgroup.

psi: pressure stall information for CPU, memory, and IO
When systems are overcommitted and resources become contended, it's hard
to tell exactly the impact this has on workload productivity, or how close
the system is to lockups and OOM kills. In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency
and throughput on the individual job can be enormous.
In order to maximize hardware utilization without sacrificing individual
job health or risk complete machine lockups, this patch implements a way
to quantify resource pressure in the system.
A kernel built with CONFIG_PSI=y creates files in /proc/pressure/ that
expose the percentage of time the system is stalled on CPU, memory, or IO,
respectively. Stall states are aggregate versions of the per-task delay
accounting delays:
cpu: some tasks are runnable but not executing on a CPU
memory: tasks are reclaiming, or waiting for swapin or thrashing cache
io: tasks are waiting for io completions
These percentages of walltime can be thought of as pressure percentages,
and they give a general sense of system health and productivity loss
incurred by resource overcommit. They can also indicate when the system
is approaching lockup scenarios and OOMs.
To do this, psi keeps track of the task states associated with each CPU
and samples the time they spend in stall states. Every 2 seconds, the
samples are averaged across CPUs - weighted by the CPUs' non-idle time to
eliminate artifacts from unused CPUs - and translated into percentages of
walltime. A running average of those percentages is maintained over 10s,
1m, and 5m periods (similar to the loadaverage).

mm, proc: add KReclaimable to /proc/meminfo
The vmstat NR_KERNEL_MISC_RECLAIMABLE counter is for kernel non-slab allocations that can be reclaimed via shrinker. In /proc/meminfo, we can show the sum of all reclaimable kernel allocations (including slab) as "KReclaimable". Add the same counter also to per-node meminfo under /sys With this counter, users will have more complete information about kernel memory usage. Non-slab reclaimable pages (currently just the ION allocator) will not be missing from /proc/meminfo, making users wonder where part of their memory went. More precisely, they already appear in MemAvailable, but without the new counter, it's not obvious why the value in MemAvailable doesn't fully correspond with the sum of other counters participating in it.

For example, the following would poison all kmalloc slabs: slub_debug=P,kmalloc* and the following would apply the default flags to all kmalloc and all block IO slabs: slub_debug=,bio*,kmalloc* Please note that a similar patch was posted by Iliyan Malchev some time ago but was never merged: https://marc.info/?l=linux-mm&m=131283905330474&w=2 Link: http://lkml.kernel.org/r/20180928111139.27962-1-atomlin@redhat.com Signed-off-by: Aaron Tomlin <atomlin@redhat.com> Acked-by: Christoph Lameter <cl@linux.com> Cc: Pekka Enberg <penberg@kernel.org> Cc: David Rientjes <rientjes@google.com> Cc: Joonsoo Kim <iamjoonsoo.kim@lge.com> Cc: Iliyan Malchev <malchev@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

powerpc updates for 4.20
Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of fairly
complicated asm with much fewer lines of C.
- Following on from that, we now maintain a cache of SLB entries for each
process and preload them on context switch. Leading to a 27% speedup for our
context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print more debug
information when they occur, and try to continue running by flushing the SLB
and reloading, rather than treating them as fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on 64-bit
Book3S. We only support up to 512TB as regular system memory, otherwise the
percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are presented
to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE flags.
- Add a driver for the PAPR SCM (storage class memory) interface, allowing
guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we need to use
a trampoline to get to ftrace_caller().
Many other smaller enhancements and cleanups.

Devicetree updates for 4.20:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
- Work to get rid of direct accesses to struct device_node name and
type pointers in preparation for removing them. New helpers for
parsing DT cpu nodes and conversions to use the helpers. printk
conversions to %pOFn for printing DT node names. Most went thru
subystem trees, so this is the remainder.
- Fixes to DT child node lookups to actually be restricted to child
nodes instead of treewide.
- Refactoring of dtb targets out of arch code. This makes the support
more uniform and enables building all dtbs on c6x, microblaze, and
powerpc.
- Various DT binding updates for Renesas r8a7744 SoC
- Vendor prefixes for Facebook, OLPC
- Restructuring of some ARM binding docs moving some peripheral bindings
out of board/SoC binding files
- New "secure-chosen" binding for secure world settings on ARM
- Dual licensing of 2 DT IRQ binding headers

IOMMU Updates for Linux v4.20
These updates bring:
- Debugfs support for the Intel VT-d driver. When enabled, it
now also exposes some of its internal data structures to
user-space for debugging purposes.
- ARM-SMMU driver now uses the generic deferred flushing
and fast-path iova allocation code. This is expected to be a
major performance improvement, as this allocation path scales
a lot better.
- Support for r8a7744 in the Renesas iommu driver

- Driver updates for bnxt_re, cxgb4, hfi1, hns, mlx5, nes, qedr, and rxe
- Memory window support in hns
- mlx5 user API 'flow mutate/steering' allows accessing the full packet
mangling and matching machinery from user space
- Support inter-working with verbs API calls in the 'devx' mlx5 user API, and
provide options to use devx with less privilege
- Modernize the use of syfs and the device interface to use attribute groups
and cdev properly for uverbs, and clean up some of the core code's device list
management
- More progress on net namespaces for RDMA devices
- Consolidate driver BAR mmapping support into core code helpers and rework
how RDMA holds poitners to mm_struct for get_user_pages cases
- First pass to use 'dev_name' instead of ib_device->name
- Device renaming for RDMA devices

sound updates for 4.20
There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
TI PCM3060

SCSI misc on 20181024
This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380, qla2xxx, lpfc, libsas, hisi_sas. In addition there's a set of mostly small updates to the target subsystem a set of conversions to the generic DMA API, which do have some potential for issues in the older drivers but we'll handle those as case by case fixes. A new myrs for the DAC960/mylex raid controllers to replace the block based DAC960 which is also being removed by Jens in this merge window. Plus the usual slew of trivial changes.
