This adds a new PCI controller driver for the Intel IXP4xx
(IX425, IXP435 etc), based on the XScale microarchitecture.

This replaces the old driver in arch/arm/mach-ixp4xx/common-pci.c
which utilized the ARM-specific BIOS32 PCI framework,
and all parameterization for such things as memory and
IO space as well as interrupt swizzling is done from the
device tree.

The plan is to phase out and delete the old driver piecemal.

The __raw_writel() and __raw_readl() are used for accessing
the PCI controller for the same reason that these accessors
are used in the timer, IRQ and GPIO drivers: the platform
will alter its address bus pattern based on whether the
system is booted in big- or little-endian mode. For this
reason all register on IXP4xx must always be accessed in
native (CPU) endianness.

This driver supports 64MB of PCI memory space, but not the
indirect access of 1GB that is available in the old driver.
We can address that later if and only if there are users
that need all 1GB of PCI address space. Krzysztof reports
having to use indirect MMIO only once for a VGA card. There
is work ongoing for general indirect MMIO. (In practice
the indirect MMIO is performed by writing address and
writing and reading values into/from a controller
register.)

Tested by booting the NSLU2, attaching a USB stick, mounting
and browsing the drive.

Patch series "kernel-doc and MAINTAINERS clean-up".

Roughly 900 warnings of about 21.000 kernel-doc warnings in the kernel
tree warn with 'cannot understand function prototype:', i.e., the
kernel-doc parser cannot parse the function's signature.  The majority,
about 600 cases of those, are just struct definitions following the
kernel-doc description.  Further, spot-check investigations suggest that
the authors of the specific kernel-doc descriptions simply were not
aware that the general format for a kernel-doc description for a
structure requires to prefix the struct name with the keyword 'struct',
as in 'struct struct_name - Brief description.'.  Details on kernel-doc
are at the Link below.

Without the struct keyword, kernel-doc does not check if the kernel-doc
description fits to the actual struct definition in the source code.
Fortunately, in roughly a quarter of these cases, the kernel-doc
description is actually complete wrt.  its corresponding struct
definition.  So, the trivial change adding the struct keyword will allow
us to keep the kernel-doc descriptions more consistent for future
changes, by checking for new kernel-doc warnings.

Also, some of the files in ./include/ are not assigned to a specific
MAINTAINERS section and hence have no dedicated maintainer.  So, if
needed, the files in ./include/ are also assigned to the fitting
MAINTAINERS section, as I need to identify whom to send the clean-up
patch anyway.

Here is the change from this kernel-doc janitorial work in the
./include/ directory for MEMORY MANAGEMENT.

This patch (of 2):

Commit a520110e ("mm: split out a new pagewalk.h header from mm.h")
adds a new file in ./include/linux, but misses to update MAINTAINERS
accordingly.  Hence,

  ./scripts/get_maintainers.pl include/linux/pagewalk.h

points only to lkml as general fallback for all files, whereas the
original include/linux/mm.h clearly marks this file part of MEMORY
MANAGEMENT.

Assign include/linux/pagewalk.h to MEMORY MANAGEMENT.

Using Landlock objects and ruleset, it is possible to tag inodes
according to a process's domain.  To enable an unprivileged process to
express a file hierarchy, it first needs to open a directory (or a file)
and pass this file descriptor to the kernel through
landlock_add_rule(2).  When checking if a file access request is
allowed, we walk from the requested dentry to the real root, following
the different mount layers.  The access to each "tagged" inodes are
collected according to their rule layer level, and ANDed to create
access to the requested file hierarchy.  This makes possible to identify
a lot of files without tagging every inodes nor modifying the
filesystem, while still following the view and understanding the user
has from the filesystem.

Add a new ARCH_EPHEMERAL_INODES for UML because it currently does not
keep the same struct inodes for the same inodes whereas these inodes are
in use.

This commit adds a minimal set of supported filesystem access-control
which doesn't enable to restrict all file-related actions.  This is the
result of multiple discussions to minimize the code of Landlock to ease
review.  Thanks to the Landlock design, extending this access-control
without breaking user space will not be a problem.  Moreover, seccomp
filters can be used to restrict the use of syscall families which may
not be currently handled by Landlock.

A Landlock object enables to identify a kernel object (e.g. an inode).
A Landlock rule is a set of access rights allowed on an object.  Rules
are grouped in rulesets that may be tied to a set of processes (i.e.
subjects) to enforce a scoped access-control (i.e. a domain).

Because Landlock's goal is to empower any process (especially
unprivileged ones) to sandbox themselves, we cannot rely on a
system-wide object identification such as file extended attributes.
Indeed, we need innocuous, composable and modular access-controls.

The main challenge with these constraints is to identify kernel objects
while this identification is useful (i.e. when a security policy makes
use of this object).  But this identification data should be freed once
no policy is using it.  This ephemeral tagging should not and may not be
written in the filesystem.  We then need to manage the lifetime of a
rule according to the lifetime of its objects.  To avoid a global lock,
this implementation make use of RCU and counters to safely reference
objects.

A following commit uses this generic object management for inodes.

This helps validating DTS files.

Changes that require mentioning:
1. reg-names
   "mspi_regs" and "bspi_regs" were renamed to "mspi" and "bspi" as that
   is what's used in DTS files and in Linux driver
2. interrupt-names
   Names were reordered. "mspi_done" has to go first as it's always
   required.
3. spi-rx-bus-width
   Property description was dropped as it's part of the
   spi-controller.yaml
4. Examples:
   * drop partitions as they are well documented elsewhere
   * regs and interrupts were formatted and reordered to match yaml
   * <0x1c> was replaced with <&gic>
   * "m25p80" node name became "flash"
   * dropped invalid "m25p,fast-read" property
   * dropped undocumented and Linux-unused "clock-names"

This rewritten binding validates cleanly using the  "dt_binding_check".
Some Linux stored DTS files will require reordering regs and interrupts
to make dtbs_check happy.

Commit 60268b0e ("hwmon: (amd_energy) modify the visibility of
the counters") restricted visibility of AMD energy counters to work
around a side-channel attack using energy data to determine which
instructions are executed. The attack is described in 'PLATYPUS:
Software-based Power Side-Channel Attacks on x86'. It relies on quick
and accurate energy readings.

This change made the counters provided by the amd_energy driver
effectively unusable for non-provileged users. However, unprivileged
read access is the whole point of hardware monitoring attributes.

An attempt to remedy the situation by limiting and randomizing access
to chip registers was rejected by AMD. Since the driver is for all
practical purposes unusable, remove it.

These are "all-in-one" CPU liquid coolers that can be monitored and
controlled through a proprietary USB HID protocol.

While the models have differently sized radiators and come with varying
numbers of fans, they are all indistinguishable at the software level.

The driver exposes fan/pump speeds and coolant temperature through the
standard hwmon sysfs interface.

Fan and pump control, while supported by the devices, are not currently
exposed.  The firmware accepts up to 61 trip points per channel
(fan/pump), but the same set of trip temperatures has to be maintained
for both; with pwmX_auto_point_Y_temp attributes, users would need to
maintain this invariant themselves.

Instead, fan and pump control, as well as LED control (which the device
also supports for 9 addressable RGB LEDs on the CPU water block) are
left for existing and already mature user-space tools, which can still
be used alongside the driver, thanks to hidraw.  A link to one, which I
also maintain, is provided in the documentation.

The implementation is based on USB traffic analysis.  It has been
runtime tested on x86_64, both as a built-in driver and as a module.
