Another merge window, another MAINTAINERS file disaster.

People have serious problems with the alphabet and sorting, and poor
Jérôme Glisse and Radim Krčmář get their names mangled by locale issues,
turning them into some mangled mess (probably others do too, but those
two stood out when sorting things again).

And we now have two copies of the same 'AS3645A LED FLASH CONTROLLER
DRIVER' in the tree and in the MAINTAINERS file, but that's a separate
issue - the duplication is real, and I left them as two entries for the
same name.

This does not try to sort the actual section pattern entries, although I
may end up doing that later.

Patch series "kmod: few code cleanups to split out umh code"

The usermode helper has a provenance from the old usb code which first
required a usermode helper.  Eventually this was shoved into kmod.c and
the kernel's modprobe calls was converted over eventually to share the
same code.  Over time the list of usermode helpers in the kernel has grown
-- so kmod is just but one user of the API.

This series is a simple logical cleanup which acknowledges the code
evolution of the usermode helper and shoves the UMH API into its own
dedicated file.  This way users of the API can later just include umh.h
instead of kmod.h.

Note despite the diff state the first patch really is just a code shove,
no functional changes are done there.  I did use git format-patch -M to
generate the patch, but in the end the split was not enough for git to
consider it a rename hence the large diffstat.

I've put this through 0-day and it gives me their machine compilation
blessings with all tests as OK.

This patch (of 4):

There's a slew of usermode helper users and kmod is just one of them.
Split out the usermode helper code into its own file to keep the logic and
focus split up.

This change provides no functional changes.

Patch series "HMM (Heterogeneous Memory Management)", v25.

Heterogeneous Memory Management (HMM) (description and justification)

Today device driver expose dedicated memory allocation API through their
device file, often relying on a combination of IOCTL and mmap calls.
The device can only access and use memory allocated through this API.
This effectively split the program address space into object allocated
for the device and useable by the device and other regular memory
(malloc, mmap of a file, share memory, â) only accessible by
CPU (or in a very limited way by a device by pinning memory).

Allowing different isolated component of a program to use a device thus
require duplication of the input data structure using device memory
allocator.  This is reasonable for simple data structure (array, grid,
image, â) but this get extremely complex with advance data
structure (list, tree, graph, â) that rely on a web of memory
pointers.  This is becoming a serious limitation on the kind of work
load that can be offloaded to device like GPU.

New industry standard like C++, OpenCL or CUDA are pushing to remove
this barrier.  This require a shared address space between GPU device
and CPU so that GPU can access any memory of a process (while still
obeying memory protection like read only).  This kind of feature is also
appearing in various other operating systems.

HMM is a set of helpers to facilitate several aspects of address space
sharing and device memory management.  Unlike existing sharing mechanism
that rely on pining pages use by a device, HMM relies on mmu_notifier to
propagate CPU page table update to device page table.

Duplicating CPU page table is only one aspect necessary for efficiently
using device like GPU.  GPU local memory have bandwidth in the TeraBytes/
second range but they are connected to main memory through a system bus
like PCIE that is limited to 32GigaBytes/second (PCIE 4.0 16x).  Thus it
is necessary to allow migration of process memory from main system memory
to device memory.  Issue is that on platform that only have PCIE the
device memory is not accessible by the CPU with the same properties as
main memory (cache coherency, atomic operations, ...).

To allow migration from main memory to device memory HMM provides a set of
helper to hotplug device memory as a new type of ZONE_DEVICE memory which
is un-addressable by CPU but still has struct page representing it.  This
allow most of the core kernel logic that deals with a process memory to
stay oblivious of the peculiarity of device memory.

When page backing an address of a process is migrated to device memory the
CPU page table entry is set to a new specific swap entry.  CPU access to
such address triggers a migration back to system memory, just like if the
page was swap on disk.  HMM also blocks any one from pinning a ZONE_DEVICE
page so that it can always be migrated back to system memory if CPU access
it.  Conversely HMM does not migrate to device memory any page that is pin
in system memory.

To allow efficient migration between device memory and main memory a new
migrate_vma() helpers is added with this patchset.  It allows to leverage
device DMA engine to perform the copy operation.

This feature will be use by upstream driver like nouveau mlx5 and probably
other in the future (amdgpu is next suspect in line).  We are actively
working on nouveau and mlx5 support.  To test this patchset we also worked
with NVidia close source driver team, they have more resources than us to
test this kind of infrastructure and also a bigger and better userspace
eco-system with various real industry workload they can be use to test and
profile HMM.

The expected workload is a program builds a data set on the CPU (from
disk, from network, from sensors, â).  Program uses GPU API (OpenCL,
CUDA, ...) to give hint on memory placement for the input data and also
for the output buffer.  Program call GPU API to schedule a GPU job, this
happens using device driver specific ioctl.  All this is hidden from
programmer point of view in case of C++ compiler that transparently
offload some part of a program to GPU.  Program can keep doing other stuff
on the CPU while the GPU is crunching numbers.

It is expected that CPU will not access the same data set as the GPU while
GPU is working on it, but this is not mandatory.  In fact we expect some
small memory object to be actively access by both GPU and CPU concurrently
as synchronization channel and/or for monitoring purposes.  Such object
will stay in system memory and should not be bottlenecked by system bus
bandwidth (rare write and read access from both CPU and GPU).

As we are relying on device driver API, HMM does not introduce any new
syscall nor does it modify any existing ones.  It does not change any
POSIX semantics or behaviors.  For instance the child after a fork of a
process that is using HMM will not be impacted in anyway, nor is there any
data hazard between child COW or parent COW of memory that was migrated to
device prior to fork.

HMM assume a numbers of hardware features.  Device must allow device page
table to be updated at any time (ie device job must be preemptable).
Device page table must provides memory protection such as read only.
Device must track write access (dirty bit).  Device must have a minimum
granularity that match PAGE_SIZE (ie 4k).

Reviewer (just hint):
Patch 1  HMM documentation
Patch 2  introduce core infrastructure and definition of HMM, pretty
         small patch and easy to review
Patch 3  introduce the mirror functionality of HMM, it relies on
         mmu_notifier and thus someone familiar with that part would be
         in better position to review
Patch 4  is an helper to snapshot CPU page table while synchronizing with
         concurrent page table update. Understanding mmu_notifier makes
         review easier.
Patch 5  is mostly a wrapper around handle_mm_fault()
Patch 6  add new add_pages() helper to avoid modifying each arch memory
         hot plug function
Patch 7  add a new memory type for ZONE_DEVICE and also add all the logic
         in various core mm to support this new type. Dan Williams and
         any core mm contributor are best people to review each half of
         this patchset
Patch 8  special case HMM ZONE_DEVICE pages inside put_page() Kirill and
         Dan Williams are best person to review this
Patch 9  allow to uncharge a page from memory group without using the lru
         list field of struct page (best reviewer: Johannes Weiner or
         Vladimir Davydov or Michal Hocko)
Patch 10 Add support to uncharge ZONE_DEVICE page from a memory cgroup (best
         reviewer: Johannes Weiner or Vladimir Davydov or Michal Hocko)
Patch 11 add helper to hotplug un-addressable device memory as new type
         of ZONE_DEVICE memory (new type introducted in patch 3 of this
         serie). This is boiler plate code around memory hotplug and it
         also pick a free range of physical address for the device memory.
         Note that the physical address do not point to anything (at least
         as far as the kernel knows).
Patch 12 introduce a new hmm_device class as an helper for device driver
         that want to expose multiple device memory under a common fake
         device driver. This is usefull for multi-gpu configuration.
         Anyone familiar with device driver infrastructure can review
         this. Boiler plate code really.
Patch 13 add a new migrate mode. Any one familiar with page migration is
         welcome to review.
Patch 14 introduce a new migration helper (migrate_vma()) that allow to
         migrate a range of virtual address of a process using device DMA
         engine to perform the copy. It is not limited to do copy from and
         to device but can also do copy between any kind of source and
         destination memory. Again anyone familiar with migration code
         should be able to verify the logic.
Patch 15 optimize the new migrate_vma() by unmapping pages while we are
         collecting them. This can be review by any mm folks.
Patch 16 add unaddressable memory migration to helper introduced in patch
         7, this can be review by anyone familiar with migration code
Patch 17 add a feature that allow device to allocate non-present page on
         the GPU when migrating a range of address to device memory. This
         is an helper for device driver to avoid having to first allocate
         system memory before migration to device memory
Patch 18 add a new kind of ZONE_DEVICE memory for cache coherent device
         memory (CDM)
Patch 19 add an helper to hotplug CDM memory

HSDK board manages its clocks using various PLLs. These PLL have same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.

Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.

We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.

As of today we add support for PLLs that generate clock for the
HSDK arc cpus, system, ddr, AXI tunnel and hdmi.

By this patch we add support for several plls (arc cpus pll and others),
so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll
and regular probing for others plls.

Add a LED flash class driver for the as3654a flash controller. A V4L2 flash
driver for it already exists (drivers/media/i2c/as3645a.c), and this driver
is based on that.

The hpsa driver now has support for all boards the cciss driver
used to support, so this patch removes the cciss driver and
make hpsa an alias to cciss.

Lguest seems to be rather unused these days. It has seen only patches
ensuring it still builds the last two years and its official state is
"Odd Fixes".

Remove it in order to be able to clean up the paravirt code.

UniPhier SoCs contain AIDET (ARM Interrupt Detector).  This is intended
to provide additional features that are not covered by GIC.  The main
purpose is to provide logic inverter to support low level and falling
edge trigger types for interrupt lines from on-board devices.

The driver is actually for T-PHY which supports USB3.0, PCIe and SATA,
and supports more SoCs now, but not just only for series of mt65xx SoCs,
so the name of file, data struct, functions etc with 'mt65xx' may cause
misunderstanding when new SoCs are supported. Here rename them to reflect
the real functions and also enhance readability.

And also update MAINTAINERS file to reflect the correct driver
