Make corrections to kernel-doc comments:
- use the struct keyword when describing structs
- use the enum keyword when describing enums
- insert colons (':') as needed in struct member descriptions
- add missing short descriptions
- convert some comments to kernel-doc format

On gfx9 ASICs with mqd_on_vram(), a compute queue MQD lives in a pinned
VRAM buffer object. Pinned BOs are skipped by the VRAM eviction done at S4
suspend, so the MQD contents are lost across hibernation and the first
submission after resume page-faults on a stale MQD.
Unpin the MQD BO at suspend so the eviction migrates it into the
hibernation image, and pin it back to VRAM on resume. The BO may return at
a different VRAM address, so refresh the kernel mapping and cached GPU
addresses and patch the MQD self-address via a new update_mqd_gpu_addr()
mqd_manager op; skip eviction with a warning if that op is not implemented.
v3: use unpin/repin instead of shadowing the MQD into a separate buffer.
v4: drop the explicit VRAM->GTT placement at evict (a bare unpin is enough
for the eviction pass to move the BO out of VRAM), and also repin at queue
destroy. KFD queue restore runs late - user processes thaw before it, and
under SR-IOV it is deferred until the VF exits full access - so once the
VM has resumed an application can destroy a queue before its MQD BO is
repinned, which would otherwise unpin an already-unpinned BO and touch a
stale q->mqd.
v5: drop support for no-HWS mode, and set q->mqd to NULL at eviction.

amdgpu_cs_pass1() dispatches on chunk_id once per chunk without
rejecting repeated ids. p->uf_bo is a single-slot field, so a
submission carrying two AMDGPU_CHUNK_ID_FENCE chunks runs
amdgpu_cs_p1_user_fence() twice, and the second run overwrites
p->uf_bo with a freshly referenced BO without dropping the reference
taken by the first.
amdgpu_cs_parser_fini() only unrefs the final p->uf_bo, so every FENCE
chunk but the last leaks a BO reference. The leaked BO outlives handle
close and process exit.
Reject duplicate FENCE chunks the same way commit fec5f8e8c6bc
("drm/amdgpu: disallow multiple BO_HANDLES chunks in one submit") did
for p->bo_list.

With the Fedora mapping in place, this patch extends it to the RHEL
family (RHEL, CentOS Stream, Rocky Linux, AlmaLinux, Oracle Linux),
which shares most Fedora package names and runs dnf (RHEL 8 and
later). The names that differ are handled by probing the enabled
repos:
- zlib.h comes from zlib-ng-compat-devel on the RHEL 10 family,
zlib-devel on RHEL 9 and earlier;
- there is no java-latest-openjdk-devel: the JDK devel package is
versioned per release, java-21-openjdk-devel on the RHEL 10
family, java-17-openjdk-devel on RHEL 9, java-11-openjdk-devel
on RHEL 8;
- libbpf-devel and capstone-devel live in the CRB repo on RHEL and
CentOS Stream 10, in EPEL on RHEL 9 and earlier;
- libbabeltrace2-devel is not packaged on the RHEL 10 family.
Packages not available on the enabled repos are skipped instead of
aborting the dnf transaction, and are listed at the end of the run, with
the repo that provides them pointed out in the header comment and help
text: a distro with CRB/EPEL enabled gets the full set, one without them
still installs what it can.
This also holds for the base set: e.g. 'rust' exists only as the
rust-toolset AppStream module on RHEL 8 and 9, where it is not
installable as a plain package, so it is skipped and noted there instead
of failing the whole dnf transaction.
The base set lists pkgconf-pkg-config instead of pkgconfig: both
families have been on pkgconf since Fedora 26 / RHEL 8, where
'pkgconfig' lives only as a virtual Provides of that subpackage, and
a minimal RHEL-family container may not have it preinstalled.
Validated on a fresh CentOS Stream 10 distrobox container, with the
CRB repo enabled, so the host system is not modified:
distrobox create --image quay.io/centos/centos:stream10
distrobox enter centos-stream10
dnf config-manager --set-enabled crb
make -C tools/perf install-build-deps
which installed the 28 available mapped packages; libbabeltrace2-devel, the
only mapped package with no RHEL 10 package, is reported at the end
of the run.
A subsequent 'make -C tools/perf feature-dump' enabled every feature
with an external dependency the RHEL 10 family provides, including
libbpf and libcapstone from the CRB repo, with only
babeltrace2-ctf-writer left out along with the deliberately unmapped
opt-in features.
Re-running the target is a no-op (dnf reports "Nothing to do"); with the
CRB repo disabled, the skipped packages are instead listed in the
end-of-run note, whose header comment and help text point out which repo
provides them.
Members of the family without dnf (RHEL 7 and earlier, e.g. Oracle
Linux 7, a yum-only distro) are rejected with an explicit error while
the dnf-based members get the full mapping.

With the Fedora and Ubuntu mappings in place, this patch adds Debian
support: Debian installs the same devel packages, under the same
names, as the Ubuntu mapping, so it reuses debian_pkg_for() and
debian_base_pkgs as-is, with only auto-detection in detect_distro()
(and the shared apt-get install path) added, keeping the script's
per-distro dispatch ready for distros with their own package names.
Validated on a fresh Debian 13 (trixie) container so the host system
is not modified:
distrobox create --image debian:trixie
distrobox enter debian-trixie
make -C tools/perf install-build-deps
which installed the 29 mapped packages; re-running the target is a
no-op (apt-get reports "0 newly installed"). A subsequent clean build
enabled the same feature set as Ubuntu: 'perf version --build-options'
shows every feature with an external dependency Debian has a package
for [on], including the BPF skeletons compiled with clang/llvm
(libLLVM), the python binding and the C++-based features, with only
the deliberately unmapped libbfd family, libperl, libunwind and the
CoreSight (libopencsd) packages [OFF].
RHEL, whose package mapping is largely similar to Fedora's, is the
remaining planned distro, to be enabled once that mapping is
validated on it.

With the framework and Fedora mapping in place, this patch adds the
Ubuntu (apt) mapping: same feature-to-package correspondence as the
Fedora one, adapted to Debian packaging conventions (libfoo-dev), on
a per-distro dispatch so future distros can pick their own mapping or
reuse one of these (Debian shares the Ubuntu mapping).
Notable differences from Fedora:
- base set: g++ (ships libstdc++-*-dev, covering cxa-demangle),
pkg-config (installed implicitly by Fedora's default toolchain
metapackage, but not by Ubuntu's), linux-libc-dev and libc6-dev
instead of kernel-headers and glibc-devel, and rustc for rust;
- cxa-demangle maps to nothing, covered by g++'s libstdc++;
- the clang-bpf-co-re test needs the clang compiler binary (Fedora's
clang-devel provides it transitively), and llvm-dev, which also
brings llvm-config (deps on the llvm package), used by the
llvm/llvm-perf tests;
- libslang maps to libslang2-dev and jvmti to default-jdk;
- the install command runs 'apt-get update' first since a fresh
container has no package indexes, unlike dnf.
Validated on a fresh Ubuntu 26.04 distrobox container so the host
system is not modified:
distrobox create --image ubuntu:26.04
distrobox enter ubuntu-26-04
make -C tools/perf install-build-deps
which installed the 29 mapped packages; a subsequent clean O= build
enabled every feature with an external dependency Ubuntu has a
package for: perf's build-options then showed all of them [on],
including the BPF skeletons requiring clang/llvm, the python binding
and the C++-based features, with only the deliberately unmapped
(deprecated) libbfd family, libperl and libunwind [OFF], and the
build linked libpfm, libbabeltrace2-ctf-writer, libcapstone,
libtraceevent, libslang, libnuma, libdw and libssl. Re-running the
target is a no-op (apt-get reports "0 newly installed").
Debian (trixie) is the next planned distro: it shares this Ubuntu
mapping, so enabling it reuses it as-is, once it gets validated on a
Debian release.

With the framework from the previous commit in place, this patch adds
the per-feature mapping for Fedora/dnf: for each feature test in
tools/build/feature/, the Fedora devel package providing the headers
or library the test compiles against, kept explicit in the script
next to the test that requires it.
Special cases:
- test-libdebuginfod.c includes <elfutils/debuginfod.h>, provided
by elfutils-debuginfod-client-devel, not elfutils-devel;
- the cxa-demangle test links against libstdc++'s builtin demangler,
pulling in libstdc++-devel;
- the BPF-oriented features (bpf, clang-bpf-co-re) get their headers
from the base packages and clang-devel.
Tests with no Fedora equivalent (bionic, compile-32, compile-x32) and
the opt-in/deprecated ones (libbfd disassembler family, GTK2, LIBPERL,
LIBUNWIND, CoreSight, and the tests perf itself doesn't check, like
libcpupower) are deliberately not mapped.
Validated on a fresh Fedora 44 toolbx container, so the host OS is not
modified:
toolbox create fedora:44
toolbox enter fedora:44
make -C tools/perf install-build-deps
which installed the 29 mapped packages; a subsequent clean O= build
enabled every feature with an external dependency Fedora provides
(feature tests went to 1, except bionic/compile-32/compile-x32, which
have no Fedora equivalent, and the libunwind-debug-frame tests, whose
symbols Fedora's libunwind does not export), linking libpfm,
libbabeltrace2-ctf-writer, libcapstone, libtraceevent, libslang and
libnuma, as well as building the BPF skeletons requiring clang/llvm.
Re-running the target is a no-op (dnf reports "Nothing to do").
RHEL and its derivatives share most Fedora package names but are
refused by the script until this mapping is validated on them.
Example of its --list option:
$ grep PRETTY_NAME /etc/os-release
PRETTY_NAME="Fedora Linux 44 (Toolbx Container Image)"

Installing the development packages needed to build perf is
error-prone on a fresh distro install: the packages are scattered
across the feature tests in tools/build/feature/, each checking for a
specific header/library, and the build only tells you what's missing
after failing a check.
This series adds a 'make -C tools/perf install-build-deps' target to
install them in one go, deriving the package list from the feature tests
themselves.
This commit adds the framework, on top of the parse-time compiler
probe guard from the previous commit:
- the install-build-deps target in tools/perf/Makefile.perf, exempted
from the config/feature detection pass, since it must run in a fresh
container, before gcc or pkg-config exist, to install them;
- the install-build-deps.sh script, with --list, --dry-run and
--distro options, distro detection (Fedora and Ubuntu), dnf and
apt-get drivers, root/passwordless-sudo handling, and the base
packages common to any build: compiler, C++ compiler, make, flex,
bison, libc and kernel headers, python3-setuptools (needed by the
python binding) and rust (checked by the rust feature test);
- the parse-time probes for optional tools, like pkg-config, use
'command -v' with stderr discarded, so a fresh container without
them gets no 'which: no pkg-config in (...)' spew from make;
- the script does not rely on 'set -e': its error paths are explicit,
since the make target runs it via $(SHELL), where a shebang option
would be ignored anyway, so direct and make-driven runs behave the
same.
The per-feature mappings, from each feature test to the devel package
providing its headers on a given distro, are added by the follow-up
patches, one per distro, together with the validation of each mapping
in a fresh container: until then the target installs just the base
toolchain.

Two parse-time probes still invoke $(CC) unconditionally:
- LP64 in tools/scripts/Makefile.arch, probing with
$(CC) -E -x c, pulled in twice by tools/perf/Makefile.perf;
- CC_NO_CLANG in tools/scripts/Makefile.include, probing with
$(CC) -dM -E -x c /dev/null.
In the corner case where gcc is not yet installed, the very setup the
install-build-deps target, added in the next patch of this series, is
meant for, these probes make even targets that never compile parse-time
spew errors like:
/bin/sh: 1: gcc: not found
/bin/sh: 1: gcc: not found
/bin/sh: 1: gcc: not found
Guard both probes with 'command -v' using the first word of CC so a
missing compiler is handled silently with the same result as a failing
probe (CC_NO_CLANG and LP64 unset/0), and with no behavior change when
the compiler is installed.
Only the first word is consulted because CC may carry arguments such as
'ccache gcc', and shell implementations differ in how 'command -v'
handles multiple words (dash only checks the first, bash any of them),
so validating the whole CC value would silently disable both probes on
some make SHELLs.

update_status() passes props.brightness straight to the hardware and
ignores the power/blank state tracked by the core. Writing 4 to the
bl_power sysfs attribute or blanking the framebuffer therefore leaves
the backlight lit.
Use backlight_get_brightness(), which returns 0 while the device is
blanked.

The lookup helpers for dim-mode and ramp-ctl take a shortcut when
lookup_tbl is NULL: they accept any u32 value without range-checking
and return success unconditionally. Out-of-range values get silently
truncated by regmap_update_bits instead of triggering the dev_warn +
default-fallback path that the other properties use.
Add a field-width check for the NULL-table case so that values
exceeding the register field maximum are rejected the same way a
table-lookup miss is.
The switching frequency table has a second hole: reserved slots use 0
as their marker, so "awinic,sw-freq-hz = <0>" matches slot 0 and
programs a reserved encoding. Make the reserved marker U32_MAX and
skip such slots during lookup.
While here, also switch the error returns to -EINVAL for consistency.

The driver reads four tuning properties without the unit suffixes that
the binding mandates: "awinic,sw-freq" instead of "awinic,sw-freq-hz",
"awinic,sw-ilmt" instead of "awinic,sw-ilmt-microamp", "awinic,iled-max"
instead of "awinic,iled-max-microamp", and "awinic,uvlo-thres" instead
of "awinic,uvlo-thres-microvolt".
As a result, device_property_read_u32() never finds these properties in
a binding-conformant device tree and silently falls back to the compiled-in
defaults for switching frequency, switching current limit, max LED current,
and UVLO threshold.
Fix by aligning the property name strings in aw99706_dt_props[] with the
binding. No value/range changes are needed since both sides already use
the same units and enumerations.

When __inject_sigp_stop() is called for a Stop and Store Status
operation, if the vCPU is running, the interrupt is marked as pending
and the status is stored by the thread performing the KVM_RUN IOCTL.
If the vCPU is already stopped, the status is stored immediately.
Storing the status means writing into userspace, which might fault, and
__inject_sigp_stop() is called from do_inject_vcpu() which in turn is
always called holding a spinlock, which is obviously an issue.
Fix this by returning -EWOULDBLOCK from __inject_sigp_stop(), and
adding a bool flag to indicate whether a store status is needed. The
callers of do_inject_vcpu() are modified to pass the pointer to the
bool flag; whenever a Store Status operation is needed, the callers can
now perform it outside the spinlock.
Opportunistically refactor kvm_s390_set_irq_state() to use
scoped_guard() and __free().

This fixes a Kconfig warning
fs/erofs/Kconfig:137:warning: range is invalid
which originates from EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS using
NR_CPUS which up to now didn't exist for ARCH=m68k. All other
architectures define this symbol, so fix the outlier.
[geert] This also fixes:
- CONFIG_EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS being set to the
literal NR_CPUS instead of a number by automatic configs like
"make allmodconfig" or "make olddefconfig",
- An infinite loop in manual configs like "make oldconfig" when
CONFIG_EROFS_FS_ZIP_LZMA_DEFAULT_MAX_STREAMS is not present or
has an invalid value in your existing .config.

When attempting to report all pending floating interrupt to userspace,
the GISA IPM bits are atomically tested and cleared, and the
corresponding interrupt description is written in the output buffer. If
the output buffer is too small, an error is returned to userspace, but
the GISA IPM bits are now lost.
Moreover, the contract of KVM_DEV_FLIC_GET_ALL_IRQS, which is the only
path to get_all_floating_irqs(), states that:
> All interrupts remain pending, i.e. are not deleted from the list of
> currently pending interrupts.
Fix by non-destructively testing for the GISA IPM bits.

alloc_pid() checks PIDNS_ADDING only on the leaf pid namespace before
making a new struct pid visible in every ancestor namespace. That is
insufficient when an unborn descendant pid namespace outlives an
ancestor whose init task has already exited. The descendant can still be
initialized later through setns(), and the new pid is then published
into the dead ancestor as well.
Keep the existing ENOMEM behavior, but require PIDNS_ADDING to be set in
every namespace that will receive the new pid before publishing any of
them. This preserves the invariant that free_pid() never decrements
pid_allocated in a namespace whose child_reaper is no longer live.

Add regulator support for the four ES8316 power domains so board
descriptions can model and control the codec supplies.
The binding patch documents AVDD, CPVDD, DVDD and PVDD as optional
supplies for ES8316, preserving compatibility with existing device-tree

the regmap and keeps them enabled for the lifetime of the I2C device.
The missing supply model was identified while reviewing the RubikPi 3

This is because the fpsimd context management code called from
__efi_fpsimd_begin() can preempt voluntarily, returning later to the EFI
code with an incorrect value for TTBR0_EL1 thanks to the deferred mm
switching used by the software PAN implementation.
Since EFI runtime services cannot preempt voluntarily and because the
fpsimd switching code does not rely on the TTBR0_EL1 mappings, simply
reorder the fpsimd switch so that it occurs before we change the
page-table.
