Every time I see libata code calling scsi_check_sense(), I get confused
why the code path that is working fine for SCSI code, is not sufficient
for libata code.
The reason is that SCSI usually gets the sense data as part of the
completion, and will thus automatically call scsi_check_sense(), which
will set the SCSI ML byte (if any).
However, for libata queued commands, we always need to fetch the sense
data via SCSI EH, and thus do not get the luxury of having
scsi_check_sense() called automatically.
Add a new helper, ata_eh_decide_disposition(), that has a ata_eh_ prefix
to more clearly highlight that this is only needed for code called by EH,
while also having a similar name to scsi_decide_disposition(), such that
it is easier to compare the libata code with the equivalent SCSI code.
Also add a big kdoc comment explaining why this helper is called/needed in
the first place.

The RXWM(RxWaterMark) sets the minimum number of free location within
the RX FIFO before the watermark is exceeded which in turn will cause
the Transport Layer to instruct the Link Layer to transmit HOLDS to the
transmitting end.
Based on the default RXWM value 0x20, RX FIFO overflow might be observed
on i.MX8QM MEK board, when some Gen3 SATA disks are used.
The FIFO overflow will result in CRC error, internal error and protocol
error, then the SATA link is not stable anymore.
To fix this issue, enlarge RX water mark setting from 0x20 to 0x29.

In ata_dev_print_quirks(), return early if ata_dev_print_info() returns
false or if we already printed quirk information. This is to avoid
printing a device quirks multiple times (that is, each time
ata_dev_revalidate() is called).
To remember if ata_dev_print_quirks() was already executed, define the
EH context flag ATA_EHI_DID_PRINT_QUIRKS and set this flag in
ata_dev_print_quirks().

Introduce the function ata_dev_print_quirks() to print the quirk flags
that will be applied to a scanned device. This new function is called
from ata_dev_quirks() when a match on a device model or device model
and revision is found for a device in the __ata_dev_quirks array.
To implement this function, the ATA_QUIRK_ flags are redefined using
the new enum ata_quirk which defines the bit shift for each quirk
flag. The array of strings ata_quirk_names is used to define the name
of each flag, which are printed by ata_dev_print_quirks().
Example output for a device listed in the __ata_dev_quirks array and
which has the ATA_QUIRK_DISABLE flag applied:
[10193.461270] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[10193.469190] ata1.00: Model 'ASMT109x- Config', rev '2143 5', applying quirks: disable
[10193.469195] ata1.00: unsupported device, disabling
[10193.481564] ata1.00: disable device
enum ata_quirk also defines the __ATA_QUIRK_MAX value as one plus the
last quirk flag defined. This value is used in ata_dev_quirks() to add a
build time check that all quirk flags fit within the unsigned int
(32-bits) quirks field of struct ata_device.

According to Wiktionary, the verb "hork" is computing slang defined as
"To foul up; to be occupied with difficulty, tangle, or unpleasantness;
to be broken" (https://en.wiktionary.org/wiki/hork#Verb). libata uses
this with the term "horkage" to refer to broken device features. Given
that this term is not widely used and its meaning unknown to many,
rename it to the more commonly used term "quirk", similar to many other
places in the kernel.
The renaming done is:
1) Rename all ATA_HORKAGE_XXX flags to ATA_QUIRK_XXX
2) Rename struct ata_device horkage field to quirks
3) Rename struct ata_blacklist_entry to struct ata_dev_quirks_entry. The
array of these structures defining quirks for known devices is
renamed __ata_dev_quirks.
4) The functions ata_dev_blacklisted() and ata_force_horkage() are
renamed to ata_dev_quirks() and ata_force_quirks() respectively.
5) All the force_horkage_xxx() macros are renamed to force_quirk_xxx()
And while at it, make sure that the type "unsigned int" is used
consistantly for quirk flags variables and data structure fields.

This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.
That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

Commit 3a7e02c040b1 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.
The complexity of those macros stems from two issues:
(a) trying to use them in situations that require a C constant
expression (in static initializers and for array sizes)
(b) the type sanity checking
and MIN_T/MAX_T avoids both of these issues.
Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.
But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.
However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.
This does exactly that.
Which in turn will then allow for much simpler implementations of
min_t()/max_t(). All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.
We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:
$ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.
'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.
All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

Pull io_uring fixes from Jens Axboe:
- Fix a syzbot issue for the msg ring cache added in this release. No
ill effects from this one, but it did make KMSAN unhappy (me)
- Sanitize the NAPI timeout handling, by unifying the value handling
into all ktime_t rather than converting back and forth (Pavel)
- Fail NAPI registration for IOPOLL rings, it's not supported (Pavel)
- Fix a theoretical issue with ring polling and cancelations (Pavel)
- Various little cleanups and fixes (Pavel)

Pull vfs fixes from Christian Brauner:
"This contains two fixes for this merge window:
VFS:
- I 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 privileged 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 as only filesystems that raise FS_USERNS_MOUNT
are known to be able to support a non-initial s_user_ns. Others may
suffer security issues, on-disk corruption or outright crash the
kernel. Prevent that by restricting such delegation to filesystems
that allow FS_USERNS_MOUNT.
Note, that this delegation requires a privileged process to
actually create the superblock so either the privileged process is
cooperaing or someone must have tricked a privileged process into
operating on a fscontext file descriptor whose origin it doesn't
know (a stupid idea).
The bug dates back to about 5 years afaict.
Misc:
- Fix hostfs parsing when the mount request comes in via the legacy
mount api.
In the legacy mount api hostfs allows to specify the host directory
mount without any key.
Restore that behavior"

fs: don't allow non-init s_user_ns for filesystems without FS_USERNS_MOUNT

Pull Rust updates from Miguel Ojeda:
"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 three 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.
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"
