Add macro definition which calculate offset of the
register with index override.
This is useful in case when there is an array of
registers which is common for all instances.
To read registers in that case it is easy to define
registers once and the index value is manually passed
to calculate proper offset of register for each instance.

The highlight is the establishment of a minimum version for the Rust
toolchain, including 'rustc' (and bundled tools) and 'bindgen'.
The initial minimum will be the pinned version we currently have, i.e.
we are just widening the allowed versions. That covers 3 stable Rust
releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta,
plus nightly.
This should already be enough for kernel developers in distributions
that provide recent Rust compiler versions routinely, such as Arch
Linux, Debian Unstable (outside the freeze period), Fedora Linux,
Gentoo Linux (especially the testing channel), Nix (unstable) and
openSUSE Slowroll and Tumbleweed.
In addition, the kernel is now being built-tested by Rust's pre-merge
CI. That is, every change that is attempting to land into the Rust
compiler is tested against the kernel, and it is merged only if it
passes. Similarly, the bindgen tool has agreed to build the kernel in
their CI too.
Thus, with the pre-merge CI in place, both projects hope to avoid
unintentional changes to Rust that break the kernel. This means that,
in general, apart from intentional changes on their side (that we
will need to workaround conditionally on our side), the upcoming Rust
compiler versions should generally work.
In addition, the Rust project has proposed getting the kernel into
stable Rust (at least solving the main blockers) as one of its three
flagship goals for 2024H2 [1].
I would like to thank Niko, Sid, Emilio et al. for their help promoting
the collaboration between Rust and the kernel.
[1] https://rust-lang.github.io/rust-project-goals/2024h2/index.html#flagship-goals
Toolchain and infrastructure:
- Support several Rust toolchain versions.
- Support several bindgen versions.
- Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc'
having been dropped last cycle.
- Provide proper error reporting for the 'rust-analyzer' target.
'kernel' crate:
- Add 'uaccess' module with a safe userspace pointers abstraction.
- Add 'page' module with a 'struct page' abstraction.
- Support more complex generics in workqueue's 'impl_has_work!' macro.
'macros' crate:
- Add 'firmware' field support to the 'module!' macro.
- Improve 'module!' macro documentation.
Documentation:
- Provide instructions on what packages should be installed to build
the kernel in some popular Linux distributions.
- Introduce the new kernel.org LLVM+Rust toolchains.
- Explain '#[no_std]'.
And a few other small bits.

Two commits are included to fix some regressions. These commits should also
be applied to the v6.10 kernel as well.
The recent integration of compiler collections introduced the technology
to check flexible array length at runtime by providing proper annotations.
In v6.10 kernel, a patch was merged into firewire subsystem to utilize it,
however the annotation was inadequate. There is also the related change for
the flexible array in sound subsystem, but it causes a regression where
the data in the payload of isochronous packet is incorrect for some
devices. These bugs are now fixed.

- Stop testing the group->parent pointer as it is not guaranteed to be
stable over a chain of operations by design. This includes a warning
which would be nice to have but it produces false positives due to
the racy nature of the check.
- Plug a race between CPUs going in and out of idle and a CPU hotplug
operation. The latter can create and connect a new hierarchy level
which is missed in the concurrent updates of CPUs which go into idle.
As a result the events of such a CPU might not be processed and
timers go stale.
Cure it by splitting the hotplug operation into a prepare and online
callback. The prepare callback is guaranteed to run on an online and
therefore active CPU. This CPU updates the hierarchy and being online
ensures that there is always at least one migrator active which
handles the modified hierarchy correctly when going idle. The online
callback which runs on the incoming CPU then just marks the CPU
active and brings it into operation.
- Improve tracing and polish the code further so it is more obvious
what's going on.

hostfs not keep the host directory when mounting. When the host
directory is none (default), fc->source is used as the host root
directory, and this is wrong. Here we use `parse_monolithic` to
handle the old mount path for parsing the root directory. For new
mount path, The `parse_param` is used for the host directory parse.

[brauner: minor fixes]
Signed-off-by: Christian Brauner <brauner@kernel.org>
Christian noticed that it is possible for a privileged user to mount
most filesystems with a non-initial user namespace in sb->s_user_ns.
When fsopen() is called in a non-init namespace the caller's namespace
is recorded in fs_context->user_ns. If the returned file descriptor is
then passed to a process priviliged in init_user_ns, that process can
call fsconfig(fd_fs, FSCONFIG_CMD_CREATE), creating a new superblock
with sb->s_user_ns set to the namespace of the process which called
fsopen().
This is problematic. We cannot assume that any filesystem which does not
set FS_USERNS_MOUNT has been written with a non-initial s_user_ns in
mind, increasing the risk for bugs and security issues.
Prevent this by returning EPERM from sget_fc() when FS_USERNS_MOUNT is
not set for the filesystem and a non-initial user namespace will be
used. sget() does not need to be updated as it always uses the user
namespace of the current context, or the initial user namespace if
SB_SUBMOUNT is set.

In a commit 1d717123bb ("ALSA: firewire-lib: Avoid
-Wflex-array-member-not-at-end warning"), DEFINE_FLEX() macro was used to
handle variable length of array for header field in struct fw_iso_packet
structure. The usage of macro has a side effect that the designated
initializer assigns the count of array to the given field. Therefore
CIP_HEADER_QUADLETS (=2) is assigned to struct fw_iso_packet.header,
while the original designated initializer assigns zero to all fields.
With CIP_NO_HEADER flag, the change causes invalid length of header in
isochronous packet for 1394 OHCI IT context. This bug affects all of
devices supported by ALSA fireface driver; RME Fireface 400, 800, UCX, UFX,
and 802.
This commit fixes the bug by replacing it with the alternative version of
macro which corresponds no initializer.

This reverts commit d3155742db.
The header_length field is byte unit, thus it can not express the number of
elements in header field. It seems that the argument for counted_by
attribute can have no arithmetic expression, therefore this commit just
reverts the issued commit.

In testing the recent kernel I found that the fbnic driver couldn't be
enabled on x86_64 builds. A bit of digging showed that the fbnic driver was
the only one to check for S390 to be n, all others had checked for !S390.
Since it is a boolean and not a tristate I am not sure it will be N. So
just update it to use the !S390 flag.
A quick check via "make menuconfig" verified that after making this change
there was an option to select the fbnic driver.
Fixes 0e03c643dc ("eth: fbnic: fix s390 build.")

The only remaining nouveau_drm.master struct member that's being used is
the mutex that protects its object tree. Move that into nouveau_drm and
remove nouveau_drm.master entirely.
A pending series to remove the "ioctl" layer between DRM and NVKM also
removes the need for object handle lookups, and hence this mutex, but
it's still required for the moment.

This allocates a new nvif_mmu in nouveau_drm, and uses it for TTM
backend memory allocations instead of nouveau_drm.master.mmu,
which is removed by a later commit that removes nouveau_drm.master
entirely.

These are some dodgy "convenience" macros for the DRM driver to peek
into NVKM state. They're still used in a few places, but don't belong
in nvif/device.h in any case.
Move them to nouveau_drv.h, and modify callers to pass a nouveau_drm
instead of an nvif_device.
v2:
- use drm->nvkm pointer for nvxx_*() macros, removing some void*
v3:
- add some explanation of the nvxx_*() macros

There's no good reason the ioremap() that results from nvif_object_map()
should fail, so add a check that the map succeeded, and remove the rd/wr
methods from display channel objects.
As this was the last user of rd/wr methods, the nvif plumbing is removed
at the same time.

The next commit removes the nvif rd/wr methods from nvif_device, which
were probably a bad idea, and mostly intended as a fallback if ioremap()
failed (or wasn't available, as was the case in some tools I once used).
The nv04 KMS driver already mapped the device, because it's mostly been
kept alive on life-support for many years and still directly bashes PRI
a lot for modesetting.
Post-nv50, I tried pretty hard to keep PRI accesses out of the DRM code,
but there's still a few random places where we do, and those were using
the rd/wr paths prior to this commit.
This allocates and maps a new nvif_device (which will replace the usage
of nouveau_drm.master.device later on), and replicates this pointer to
all other possible users.
This will be cleaned up by the end of another patch series, after it's
been made safe to do so.

These were once used by used by userspace tools (with nvkm built as a
library), to access multiple GPUs from a single nvif_client.
The DRM code just uses the driver's default device, so remove the
arguments.

This was once used by userspace tools (with nvkm built as a library), as
a way to select a "default device".
The DRM code doesn't need this at all as clients only have access to a
single device already, so inherit the value from its parent.
