   - Clear Root Port I/O Space, Memory Space, and Bus Master Enable bits
     at startup; PCI core will set those as necessary (Pali Rohár)
   - When operating as a Root Port, set class code to "PCI Bridge"
     instead of the default "Mass Storage Controller" (Pali Rohár)

0d16cfd46b Docs/admin-guide/mm/pagemap: wordsmith page flags descriptions
Some descriptions of page flags in 'pagemap.rst' are written in
assumption of none-rst, which respects every new line, as below:

    7 - SLAB
       page is managed by the SLAB/SLOB/SLUB/SLQB kernel memory allocator
       When compound page is used, SLUB/SLQB will only set this flag on the head

Because rst ignores the new line between the first sentence and second
sentence, resulting html looks a little bit weird, as below.

    7 - SLAB
    page is managed by the SLAB/SLOB/SLUB/SLQB kernel memory allocator When
                                                                       ^
    compound page is used, SLUB/SLQB will only set this flag on the head
    page; SLOB will not flag it at all.

This change makes it more natural and consistent with other parts in the
rendered version.

b1eee3c548 Docs/admin-guide/mm/damon/start: simplify the content
Information in 'TL; DR' section of 'Getting Started' is duplicated in
other parts of the doc.  It is also asking readers to visit the access
pattern visualizations gallery web site to show the results of example
visualization commands, while the users of the commands can use terminal
output.

To make the doc simple, this removes the duplicated 'TL; DR' section and
replaces the visualization example commands with versions using terminal
outputs.

4f612ed3f7 kfence: default to dynamic branch instead of static keys mode
We have observed that on very large machines with newer CPUs, the static
key/branch switching delay is on the order of milliseconds.  This is due
to the required broadcast IPIs, which simply does not scale well to
hundreds of CPUs (cores).  If done too frequently, this can adversely
affect tail latencies of various workloads.

One workaround is to increase the sample interval to several seconds,
while decreasing sampled allocation coverage, but the problem still
exists and could still increase tail latencies.

As already noted in the Kconfig help text, there are trade-offs: at
lower sample intervals the dynamic branch results in better performance;
however, at very large sample intervals, the static keys mode can result
in better performance -- careful benchmarking is recommended.

Our initial benchmarking showed that with large enough sample intervals
and workloads stressing the allocator, the static keys mode was slightly
better.  Evaluating and observing the possible system-wide side-effects
of the static-key-switching induced broadcast IPIs, however, was a blind
spot (in particular on large machines with 100s of cores).

Therefore, a major downside of the static keys mode is, unfortunately,
that it is hard to predict performance on new system architectures and
topologies, but also making conclusions about performance of new
workloads based on a limited set of benchmarks.

Most distributions will simply select the defaults, while targeting a
large variety of different workloads and system architectures.  As such,
the better default is CONFIG_KFENCE_STATIC_KEYS=n, and re-enabling it is
only recommended after careful evaluation.

For reference, on x86-64 the condition in kfence_alloc() generates
exactly
2 instructions in the kmem_cache_alloc() fast-path:

 | ...
 | cmpl   $0x0,0x1a8021c(%rip)  # ffffffff82d560d0 <kfence_allocation_gate>
 | je     ffffffff812d6003      <kmem_cache_alloc+0x243>
 | ...

which, given kfence_allocation_gate is infrequently modified, should be
well predicted by most CPUs.

755804d169 zram: introduce an aged idle interface
This change introduces an aged idle interface to the existing idle sysfs
file for zram.

When CONFIG_ZRAM_MEMORY_TRACKING is enabled the idle file now also
accepts an integer argument.  This integer is the age (in seconds) of
pages to mark as idle.  The idle file still supports 'all' as it always
has.  This new approach allows for much more control over which pages
get marked as idle.

Commit e83a437faa ("mm/memory_hotplug: introduce "auto-movable" online
policy") introduced a new memory online policy to automatically select a
zone for memory blocks to be onlined.  It added a way to set the active
online policy and tunables for the auto-movable online policy.

Follow-up commits tweaked the "auto-movable" policy to also consider
memory device details when selecting zones for memory blocks to be
onlined.

Let's document the new toggles and how the two online policies we have
work.

b5389086ad hugetlbfs: extend the definition of hugepages parameter to support node allocation
We can specify the number of hugepages to allocate at boot.  But the
hugepages is balanced in all nodes at present.  In some scenarios, we
only need hugepages in one node.  For example: DPDK needs hugepages
which are in the same node as NIC.

If DPDK needs four hugepages of 1G size in node1 and system has 16 numa
nodes we must reserve 64 hugepages on the kernel cmdline.  But only four
hugepages are used.  The others should be free after boot.  If the
system memory is low(for example: 64G), it will be an impossible task.

So extend the hugepages parameter to support specifying hugepages on a
specific node.  For example add following parameter:

  hugepagesz=1G hugepages=0:1,1:3

It will allocate 1 hugepage in node0 and 3 hugepages in node1.

f7df2b1cf0 tools/vm/page_owner_sort.c: count and sort by mem
When viewing page owner information, we may be more concerned about the
total memory rather than the times of stack appears.  Therefore, the
following adjustments are made:

1. Added the statistics on the total number of pages.

2. Added the optional parameter "-m" to configure the program to sort by
   memory (total pages).

The general output of page_owner is as follows:

	Page allocated via order XXX, ...
	PFN XXX ...
	 // Detailed stack

	Page allocated via order XXX, ...
	PFN XXX ...
	 // Detailed stack

The original page_owner_sort ignores PFN rows, puts the remaining rows
in buf, counts the times of buf, and finally sorts them according to the
times.  General output:

	XXX times:
	Page allocated via order XXX, ...
	 // Detailed stack

Now, we use regexp to extract the page order value from the buf, and
count the total pages for the buf.  General output:

	XXX times, XXX pages:
	Page allocated via order XXX, ...
	 // Detailed stack

By default, it is still sorted by the times of buf; If you want to sort
by the pages nums of buf, use the new -m parameter.

38e719ab26 hugetlb: support node specified when using cma for gigantic hugepages
Now the size of CMA area for gigantic hugepages runtime allocation is
balanced for all online nodes, but we also want to specify the size of
CMA per-node, or only one node in some cases, which are similar with
patch [1].

For example, on some multi-nodes systems, each node's memory can be
different, allocating the same size of CMA for each node is not suitable
for the low-memory nodes.  Meanwhile some workloads like DPDK mentioned
by Zhenguo in patch [1] only need hugepages in one node.

On the other hand, we have some machines with multiple types of memory,
like DRAM and PMEM (persistent memory).  On this system, we may want to
specify all the hugepages only on DRAM node, or specify the proportion
of DRAM node and PMEM node, to tuning the performance of the workloads.

Thus this patch adds node format for 'hugetlb_cma' parameter to support
specifying the size of CMA per-node.  An example is as follows:

  hugetlb_cma=0:5G,2:5G

which means allocating 5G size of CMA area on node 0 and node 2
respectively.  And the users should use the node specific sysfs file to
allocate the gigantic hugepages if specified the CMA size on that node.

79dfc69552 hugetlb: add demote hugetlb page sysfs interfaces
Patch series "hugetlb: add demote/split page functionality", v4.

The concurrent use of multiple hugetlb page sizes on a single system is
becoming more common.  One of the reasons is better TLB support for
gigantic page sizes on x86 hardware.  In addition, hugetlb pages are
being used to back VMs in hosting environments.

When using hugetlb pages to back VMs, it is often desirable to
preallocate hugetlb pools.  This avoids the delay and uncertainty of
allocating hugetlb pages at VM startup.  In addition, preallocating huge
pages minimizes the issue of memory fragmentation that increases the
longer the system is up and running.

In such environments, a combination of larger and smaller hugetlb pages
are preallocated in anticipation of backing VMs of various sizes.  Over
time, the preallocated pool of smaller hugetlb pages may become depleted
while larger hugetlb pages still remain.  In such situations, it is
desirable to convert larger hugetlb pages to smaller hugetlb pages.

Converting larger to smaller hugetlb pages can be accomplished today by
first freeing the larger page to the buddy allocator and then allocating
the smaller pages.  For example, to convert 50 GB pages on x86:

  gb_pages=`cat .../hugepages-1048576kB/nr_hugepages`
  m2_pages=`cat .../hugepages-2048kB/nr_hugepages`
  echo $(($gb_pages - 50)) > .../hugepages-1048576kB/nr_hugepages
  echo $(($m2_pages + 25600)) > .../hugepages-2048kB/nr_hugepages

On an idle system this operation is fairly reliable and results are as
expected.  The number of 2MB pages is increased as expected and the time
of the operation is a second or two.

However, when there is activity on the system the following issues
arise:

1) This process can take quite some time, especially if allocation of
   the smaller pages is not immediate and requires migration/compaction.

2) There is no guarantee that the total size of smaller pages allocated
   will match the size of the larger page which was freed. This is
   because the area freed by the larger page could quickly be
   fragmented.

In a test environment with a load that continually fills the page cache
with clean pages, results such as the following can be observed:

  Unexpected number of 2MB pages allocated: Expected 25600, have 19944
  real    0m42.092s
  user    0m0.008s
  sys     0m41.467s

To address these issues, introduce the concept of hugetlb page demotion.
Demotion provides a means of 'in place' splitting of a hugetlb page to
pages of a smaller size.  This avoids freeing pages to buddy and then
trying to allocate from buddy.

Page demotion is controlled via sysfs files that reside in the per-hugetlb
page size and per node directories.

 - demote_size
        Target page size for demotion, a smaller huge page size. File
        can be written to chose a smaller huge page size if multiple are
        available.

 - demote
        Writable number of hugetlb pages to be demoted

To demote 50 GB huge pages, one would:

  cat .../hugepages-1048576kB/free_hugepages   /* optional, verify free pages */
  cat .../hugepages-1048576kB/demote_size      /* optional, verify target size */
  echo 50 > .../hugepages-1048576kB/demote

Only hugetlb pages which are free at the time of the request can be
demoted.  Demotion does not add to the complexity of surplus pages and
honors reserved huge pages.  Therefore, when a value is written to the
sysfs demote file, that value is only the maximum number of pages which
will be demoted.  It is possible fewer will actually be demoted.  The
recently introduced per-hstate mutex is used to synchronize demote
operations with other operations that modify hugetlb pools.

Real world use cases
--------------------
The above scenario describes a real world use case where hugetlb pages
are used to back VMs on x86.  Both issues of long allocation times and
not necessarily getting the expected number of smaller huge pages after
a free and allocate cycle have been experienced.  The occurrence of
these issues is dependent on other activity within the host and can not
be predicted.

This patch (of 5):

Two new sysfs files are added to demote hugtlb pages.  These files are
both per-hugetlb page size and per node.  Files are:

  demote_size - The size in Kb that pages are demoted to. (read-write)
  demote - The number of huge pages to demote. (write-only)

By default, demote_size is the next smallest huge page size.  Valid huge
page sizes less than huge page size may be written to this file.  When
huge pages are demoted, they are demoted to this size.

Writing a value to demote will result in an attempt to demote that
number of hugetlb pages to an appropriate number of demote_size pages.

NOTE: Demote interfaces are only provided for huge page sizes if there
is a smaller target demote huge page size.  For example, on x86 1GB huge
pages will have demote interfaces.  2MB huge pages will not have demote
interfaces.

This patch does not provide full demote functionality.  It only provides
the sysfs interfaces.

It also provides documentation for the new interfaces.

threads [1][2].  It presents the exception case of shared memory
management from the pagemap's point of view.  It briefly describes what
is missing, why it is missing and alternatives to the pagemap for page
info retrieval in user space.

In short, the kernel does not keep track of PTEs for swapped out shared
pages within the processes that references them.  Thus, the
proc/pid/pagemap tool cannot print the swap destination of the shared
memory pages, instead setting the pagemap entry to zero for both
non-allocated and swapped out pages.  This can create confusion for
users who need information on swapped out pages.

The reasons why maintaining the PTEs of all swapped out shared pages
among all processes while maintaining similar performance is not a
trivial task, or a desirable change, have been discussed extensively
[1][3][4][5].  There are also arguments for why this arguably missing
information should eventually be exposed to the user in either a future
pagemap patch, or by an alternative tool.

Mention the current missing information in the pagemap and alternatives
on how to retrieve it, in case someone stumbles upon unexpected
behaviour.

58056f7750 memcg, kmem: further deprecate kmem.limit_in_bytes
The deprecation process of kmem.limit_in_bytes started with the commit
0158115f70 ("memcg, kmem: deprecate kmem.limit_in_bytes") which also
explains in detail the motivation behind the deprecation.  To summarize,
it is the unexpected behavior on hitting the kmem limit.  This patch
moves the deprecation process to the next stage by disallowing to set
the kmem limit.  In future we might just remove the kmem.limit_in_bytes
file completely.

fe91c4725a SCSI misc on 20211105
This series consists of the usual driver updates (ufs, smartpqi, lpfc,
 target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
 fixes.  Notable core changes are the removal of scsi->tag which caused
 some churn in obsolete drivers and a sweep through all drivers to call
 scsi_done() directly instead of scsi->done() which removes a pointer
 indirection from the hot path and a move to register core sysfs files
 earlier, which means they're available to KOBJ_ADD processing, which
 necessitates switching all drivers to using attribute groups.

 Nothing major in here at all, just lots of tiny serial and tty driver
 updates for various reported things, and some good cleanups.  These
 include:
 	- more good tty api cleanups from Jiri
 	- stm32 serial driver updates
 	- softlockup fix for non-preempt systems under high serial load
 	- rpmsg serial driver update
 	- 8250 drivers updates and fixes
 	- n_gsm line discipline fixes and updates as people are finally
 	  starting to use it.
 
 All of these have been in linux-next for a while now with no reported
 issues.

d461e96cd2 ARM: SoC drivers for 5.16
These are all the driver updates for SoC specific drivers. There
 are a couple of subsystems with individual maintainers picking up
 their patches here:
 
  - The reset controller subsystem add support for a few new SoC
    variants to existing drivers, along with other minor improvements
 
  - The OP-TEE subsystem gets a driver for the ARM FF-A transport
 
  - The memory controller subsystem has improvements for Tegra,
    Mediatek, Renesas, Freescale and Broadcom specific drivers.
 
  - The tegra cpuidle driver changes get merged through this
    tree this time. There are only minor changes, but they depend
    on other tegra driver updates here.
 
  - The ep93xx platform finally moves to using the drivers/clk/
    subsystem, moving the code out of arch/arm in the process.
    This depends on a small sound driver change that is included
    here as well.
 
  - There are some minor updates for Qualcomm and Tegra specific
    firmware drivers.
 
 The other driver updates are mainly for drivers/soc, which contains
 a mixture of vendor specific drivers that don't really fit elsewhere:
 
  - Mediatek drivers gain more support for MT8192, with new support for
    hw-mutex and mmsys routing, plus support for reset lines in the
    mmsys driver.
 
  - Qualcomm gains a new "sleep stats" driver, and support for
    the "Generic Packet Router" in the APR driver.
 
  - There is a new user interface for routing the UARTS on ASpeed
    BMCs, something that apparently nobody else has needed so far.
 
  - More drivers can now be built as loadable modules, in particular
    for Broadcom and Samsung platforms.
 
  - Lots of improvements to the TI sysc driver for better suspend/resume
    support
 
 Finally, there are lots of minor cleanups and new device IDs for
 amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape,
 allwinner, broadcom, and omap.

Merge tag 'drivers-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are all the driver updates for SoC specific drivers. There are a
  couple of subsystems with individual maintainers picking up their
  patches here:

   - The reset controller subsystem add support for a few new SoC
     variants to existing drivers, along with other minor improvements

   - The OP-TEE subsystem gets a driver for the ARM FF-A transport

   - The memory controller subsystem has improvements for Tegra,
     Mediatek, Renesas, Freescale and Broadcom specific drivers.

   - The tegra cpuidle driver changes get merged through this tree this
     time. There are only minor changes, but they depend on other tegra
     driver updates here.

   - The ep93xx platform finally moves to using the drivers/clk/
     subsystem, moving the code out of arch/arm in the process. This
     depends on a small sound driver change that is included here as
     well.

   - There are some minor updates for Qualcomm and Tegra specific
     firmware drivers.

  The other driver updates are mainly for drivers/soc, which contains a
  mixture of vendor specific drivers that don't really fit elsewhere:

   - Mediatek drivers gain more support for MT8192, with new support for
     hw-mutex and mmsys routing, plus support for reset lines in the
     mmsys driver.

   - Qualcomm gains a new "sleep stats" driver, and support for the
     "Generic Packet Router" in the APR driver.

   - There is a new user interface for routing the UARTS on ASpeed BMCs,
     something that apparently nobody else has needed so far.

   - More drivers can now be built as loadable modules, in particular
     for Broadcom and Samsung platforms.

   - Lots of improvements to the TI sysc driver for better
     suspend/resume support"

  Finally, there are lots of minor cleanups and new device IDs for
  amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
  layerscape, allwinner, broadcom, and omap"

ae45d84fc3 ARM: SoC DT updates for v5.16
This is a rather large update for the ARM devicetree files, after a few
 quieter releases, with 775 total commits and 47 branches pulled into
 this one. There are 5 new SoC types plus some minor variations, and
 a total of 60 new machines, so I'm limiting the summary to the main
 noteworthy items:
 
  - Apple M1 gain support for PCI and pinctrl, getting a bit
    closer to a usable system out of the box.
 
  - Qualcomm gains support for Snapdragon 690 (aka SM6350) as
    well as SM7225, 11 new smartphones, and three additional
    Chromebooks, and improvements all over the place.
 
  - Samsung gains support for ExynosAutov9, an automotive version
    of their smartphone SoC, but otherwise no major changes.
 
  - Microchip adds the SAMA5D29 SoC in the SAMA5 family, and a
    number of improvements for the recently added SAMA7 family.
    The LAN966 SoC that was added in the platform code does not
    have dts files yet. Two board files are added for the older
    at91sam9g20 SoC
 
  - Aspeed supports two additional server boards using their AST2600
    as BMC, and improves support for qemu models
 
  - Rockchip RK3566/RK3688 gets added, along with six new
    development boards using RK3328/RK3399/RK3566, and one
    Chromebook tablet.
 
  - Two NAS boxes are added using the ARMv4 based Gemini platform
 
  - One new board is added to the Intel Arria SoC FPGA family
 
  - Marvell adds one network switch based on Armada 381 and the
    new MOCHAbin 7040 development board
 
  - NXP adds support for the S32G2 automotive SoC, two imx6 based
    ebook readers, and three additional development boards, which
    is notably less than their usual additions, but they also gain
    improvements to their many existing boards
 
  - STmicroelectronics adds their stm32mp13 SoC family along with
    a reference board
 
  - Renesas adds new versions of their R-Car Gen3 SoCs and many
    updates for their older generations
 
  - Broadcom adds support for a number of Cisco Meraki wireless
    controllers, along with two new boards and other updates for
    BCM53xx/BCM47xx networking SoCs and the Raspberry Pi
    boards
 
  - Mediatek improves support for the MT81xx SoCs used in Chromebooks
    as well as the MT76xx networking SoCs
 
  - NVIDIA adds a number of cleanups and additional support for
    more hardware on the already supported machines
 
  - TI K3 adds support for three new boards along with cleanups
 
  - Toshiba adds one board for the Visconti family
 
  - Xilinx adds five new ZynqMP based machines
 
  - Amlogic support is added for the Radxa Zero and two Jethub
    home automation controllers, along with changes to other
    machines
 
  - Rob Herring continues his work on fixing dtc warnings all over
    the tree.
 
  - Minor updates for TI OMAP, Mstar, Allwinner/sunxi, Hisilicon,
    Ux500, Unisoc

ff0700f036 sound updates for 5.16-rc1
Lots of code development have been see in ASoC side as usual, while
 the continued development on memalloc helper and USB-audio low-
 latency support are found in the rest.  Note that a few changes in the
 unusual places like arch/sh are included, which are a part of ASoC DAI
 format cleanups.
 
 ALSA core:
 - Continued memallloc helper updates and cleanups, now supporting
   non-coherent and non-contiguous pages
 - Fixes for races in mixer OSS layer
 
 ASoC:
 - A new version of the audio graph card which supports a wider range
   of systems
 - Several conversions to YAML DT bindings
 - Continuing cleanups to the SOF and Intel code
 - Move of the Cirrus DSP framework into drivers/firmware to allow for
   future use by non-audio DSPs
 - An overhaul of the cs42l42 driver, correcting many problems
 - DAI format terminology conversions over many drivers for cleanups
 - Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim
   MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia
   Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS,
   RT5682S, and RT9120 and Rockchip RV1126 and RK3568
 
 USB-audio:
 - Continued improvements on low-latency playback
 - Quirks for Pioneer devices, Line6 HX-Stomp XL, Audient iD14
 
 HD-audio:
 - Reduce excessive udelay() calls on Intel platforms; this should
   reduce the CPU load with PulseAudio
 - Quirks for HP and Clevo laptops
