rust: sync: implement AsRef<T> for Arc<T>
This trait lets you use `Arc<T>` in code that is generic over smart pointer types. The `AsRef` trait should be implemented on all smart pointers. The standard library also implements it on the ordinary `Arc`.

rust: sync: add Arc::ptr_eq
Add a method for comparing whether two `Arc` pointers reference the same underlying object. This comparison can already be done by getting a reference to the inner values and comparing whether the references have the same address. However, writing `Arc::ptr_eq(a, b)` is generally less error-prone than doing the same check on the references, since you might otherwise accidentally compare the two `&Arc<T>` references instead, which wont work because those are pointers to pointers to the inner value, when you just want to compare the pointers to the inner value. Also, this method might optimize better because getting a reference to the inner value involves offsetting the pointer, which this method does not need to do.

rust: error: add missing error codes
This adds the error codes from `include/linux/errno.h` to the list of Rust error constants. These errors were not included originally, because they are not supposed to be visible from userspace. However, they are still a perfectly valid error to use when writing a kernel driver. For example, you might want to return ERESTARTSYS if you receive a signal during a call to `schedule`. This patch inserts an annotation to skip rustfmt on the list of error codes. Without it, three of the error codes are split over several lines, which looks terribly inconsistent.

rust: str: add conversion from CStr to CString
These methods can be used to copy the data in a temporary c string into a separate allocation, so that it can be accessed later even if the original is deallocated. The API in this change mirrors the standard library API for the `&str` and `String` types. The `ToOwned` trait is not implemented because it assumes that allocations are infallible.

rust: error: allow specifying error type on Result
Currently, if the `kernel::error::Result` type is in scope (which is often is, since it's in the kernel's prelude), you cannot write `Result<T, SomeOtherErrorType>` when you want to use a different error type than `kernel::error::Error`. To solve this we change the error type from being hard-coded to just being a default generic parameter. This still lets you write `Result<T>` when you just want to use the `Error` error type, but also lets you write `Result<T, SomeOtherErrorType>` when necessary.

rust: macros: replace Self with the concrete type in #[pin_data]
When using `#[pin_data]` on a struct that used `Self` in the field types, a type error would be emitted when trying to use `pin_init!`. Since an internal type would be referenced by `Self` instead of the defined struct. This patch fixes this issue by replacing all occurrences of `Self` in the `#[pin_data]` macro with the concrete type circumventing the issue. Since rust allows type definitions inside of blocks, which are expressions, the macro also checks for these and emits a compile error when it finds `trait`, `enum`, `union`, `struct` or `impl`. These keywords allow creating new `Self` contexts, which conflicts with the current implementation of replacing every `Self` ident. If these were allowed, some `Self` idents would be replaced incorrectly.

docs: rust: point directly to the standalone installers
The Quick Start guide points to the Rust programming language front page when it mentions the possibility of using the standalone installers instead of `rustup`. This was done to have a hopefully stable link, but it is not too helpful: readers need to figure out how to reach the standalone installers from there. Thus point directly to the page (and anchor) with the table that contains the standalone installers (plus signing key etc.). If the link breaks in the future, we can always update it as needed. And anyway having the full link includes the domain and gives more information about where the old docs were in such a broken link case, which may help.

.gitattributes: set diff driver for Rust source code files
Git supports a builtin Rust diff driver [1] since v2.23.0 (2019).
It improves the choice of hunk headers in some cases, such as
diffs within methods, since those are indented in Rust within
an `impl` block, and therefore the default diff driver would
pick the outer `impl` block instead (rather than the method
where the changed code is).
For instance, with the default diff driver:
@@ -455,6 +455,8 @@ impl fmt::Write for RawFormatter {
// Amount that we can copy. `saturating_sub` ensures we get 0 if `pos` goes past `end`.
let len_to_copy = core::cmp::min(pos_new, self.end).saturating_sub(self.pos);
+ test_diff_driver();
+
if len_to_copy > 0 {
// SAFETY: If `len_to_copy` is non-zero, then we know `pos` has not gone past `end`

rust: upgrade to Rust 1.68.2
This is the first upgrade to the Rust toolchain since the initial Rust
merge, from 1.62.0 to 1.68.2 (i.e. the latest).
# Context
The kernel currently supports only a single Rust version [1] (rather
than a minimum) given our usage of some "unstable" Rust features [2]
which do not promise backwards compatibility.
The goal is to reach a point where we can declare a minimum version for
the toolchain. For instance, by waiting for some of the features to be
stabilized. Therefore, the first minimum Rust version that the kernel
will support is "in the future".
# Upgrade policy
Given we will eventually need to reach that minimum version, it would be
ideal to upgrade the compiler from time to time to be as close as
possible to that goal and find any issues sooner. In the extreme, we
could upgrade as soon as a new Rust release is out. Of course, upgrading
so often is in stark contrast to what one normally would need for GCC
and LLVM, especially given the release schedule: 6 weeks for Rust vs.
half a year for LLVM and a year for GCC.
Having said that, there is no particular advantage to updating slowly
either: kernel developers in "stable" distributions are unlikely to be
able to use their distribution-provided Rust toolchain for the kernel
anyway [3]. Instead, by routinely upgrading to the latest instead,
kernel developers using Linux distributions that track the latest Rust
release may be able to use those rather than Rust-provided ones,
especially if their package manager allows to pin / hold back /
downgrade the version for some days during windows where the version may
not match. For instance, Arch, Fedora, Gentoo and openSUSE all provide
and track the latest version of Rust as they get released every 6 weeks.
Then, when the minimum version is reached, we will stop upgrading and
decide how wide the window of support will be. For instance, a year of
Rust versions. We will probably want to start small, and then widen it
over time, just like the kernel did originally for LLVM, see commit

rust: arc: fix intra-doc link in Arc<T>::init
`Arc<T>::init` refers to `Arc<T>::pin_init` via an intra-doc link
using the text `pin_init`, rather than more explicitly, which makes
`rustdoc` point it to the `pin_init!` macro instead.
This is required for the compiler upgrade since the newer `rustdoc`
would trigger the `broken_intra_doc_links` lint [1], but in this case
the macro was not the intended target to begin with, and so the actual
fix is to make it point to the right place, regardless of the upgrade.
Thus make it more explicit.

A set of fixes for interrupt chip drivers:
- Prevent loss of state in the MIPS GIC interrupt controller.
- Disable pseudo NMIs on Mediatek based Chromebooks as they have
firmware issues which cause instantenous chrashes and freezes
wen pseudo NMIs are used.
- Fix the error handling path in the MBIGEN driver and a defined but not
used warning in the meson-gpio interrupt chip driver.

Char/Misc fixes for 6.4-rc4
Here are some small driver fixes for 6.4-rc4. They are just two
different types:
- binder fixes and reverts for reported problems and regressions in
the binder "driver".
- coresight driver fixes for reported problems.
All of these have been in linux-next for over a week with no reported
problems.

ARM: SoC fixes for 6.4
There have not been a lot of fixes for for the soc tree in 6.4, but these have been sitting here for too long. For the devicetree side, there is one minor warning fix for vexpress, the rest all all for the the NXP i.MX platforms: SoC specific bugfixes for the iMX8 clocks and its USB-3.0 gadget device, as well as board specific fixes for regulators and the phy on some of the i.MX boards. The microchip risc-v and arm32 maintainers now also add a shared maintainer file entry for the arm64 parts. The remaining fixes are all for firmware drivers, addressing mistakes in the optee, scmi and ff-a firmware driver implementation, mostly in the error handling code, incorrect use of the alloc_workqueue() interface in SCMI, and compatibility with corner cases of the firmware implementation. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmRxHzQACgkQYKtH/8kJ UidW5g//W9PQIG70mWZr1uDIluUyyEnSp4gsuPHgDSSrQS7paSud3E8FF7ofmiKQ 57Tuv+y9vVJtmzfWlR+L1VybPrOSGAsuzqag9/inwcfew7yPlOU9Z9Dse1v2/ClA GWuMsWjcQmCBgmluSMBupt6ZWbz3cZaLcJAuGmIYzUbeL/Cx45EnMnjc3ESpa6Ca ow3t/uoAk+KSgjMLyf2bec8BUiueRCJrqQmYHAg4utvehfTUl98epinRbtoi0VDR 5HYlYvYLi0u0em14Nx1CaNVgvM13C5/LOoJNFlDcV+x2LCW9aPCqiRi5vfalOGwj r0NiA3cPIizJc4oiiK3+PqT5PGfBlkjJx/C6LfCZRsRnu6XegXo/prCNELOJPesD ecRU9NXAjWup5PLSRPNRz3ekI4yySbM6JnoNEe+I7+djrSkmtjGBggwX6Is+fSY0 KkwhKEml6pI9w9zXh0f63R8QvKo91SUPIe/PgV65p4yeRf5JJgxeJRDk/dyzDfj8 rViloBfTndS762mI7l46xEs3wWY0+CcxRoh53VFe50pqHbrIMY21pjarMEhMSI9V dFnkXcIIJwkt8TcoLOPMD0xSb0g3C2bEnAK253EeNtBkCdp7eLGYmUdTle+cOjyw 0wafZSrbtBStLby+9F4zxYbrbArqxH5GrKanuX6jyiLtYefAa2U= =XeTU -----END PGP SIGNATURE----- Merge tag 'arm-fixes-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "There have not been a lot of fixes for for the soc tree in 6.4, but these have been sitting here for too long.

cxl: Explicitly initialize resources when media is not ready
When media is not ready do not assume that the capacity information from
the identify command is valid, i.e. ->total_bytes
->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly
zero out the capacity resources and exit early.
Given zero-init of those fields this patch is functionally equivalent to
the prior state, but it improves readability and robustness going
forward.

Arm FF-A fixes for v6.4
Quite a few fixes to address set of assorted issues:
1. NULL pointer dereference if the ffa driver doesn't provide remove()
callback as it is currently executed unconditionally
2. FF-A core probe failure on systems with v1.0 firmware as the new
partition info get count flag is used unconditionally
3. Failure to register more than one logical partition or service within
the same physical partition as the device name contains only VM ID
which will be same for all but each will have unique UUID.
4. Rejection of certain memory interface transmissions by the receivers
(secure partitions) as few MBZ fields are non-zero due to lack of
explicit re-initialization of those fields

module: error out early on concurrent load of the same module file
It turns out that udev under certain circumstances will concurrently try
to load the same modules over-and-over excessively. This isn't a kernel
bug, but it ends up affecting the kernel, to the point that under
certain circumstances we can fail to boot, because the kernel uses a lot
of memory to read all the module data all at once.
Note that it isn't a memory leak, it's just basically a thundering herd
problem happening at bootup with a lot of CPUs, with the worst cases
then being pretty bad.
Admittedly the worst situations are somewhat contrived: lots and lots of
CPUs, not a lot of memory, and KASAN enabled to make it all slower and
as such (unintentionally) exacerbate the problem.
Luis explains: [1]
"My best assessment of the situation is that each CPU in udev ends up
triggering a load of duplicate set of modules, not just one, but *a
lot*. Not sure what heuristics udev uses to load a set of modules per
CPU."
Petr Pavlu chimes in: [2]
"My understanding is that udev workers are forked. An initial kmod
context is created by the main udevd process but no sharing happens
after the fork. It means that the mentioned memory pool logic doesn't
really kick in.
Multiple parallel load requests come from multiple udev workers, for
instance, each handling an udev event for one CPU device and making
the exactly same requests as all others are doing at the same time.
The optimization idea would be to recognize these duplicate requests
at the udevd/kmod level and converge them"
Note that module loading has tried to mitigate this issue before, see
for example commit

Pull vfs fixes from Christian Brauner:
- During the acl rework we merged this cycle the generic_listxattr()
helper had to be modified in a way that in principle it would allow
for POSIX ACLs to be reported. At least that was the impression we
had initially. Because before the acl rework POSIX ACLs would be
reported if the filesystem did have POSIX ACL xattr handlers in
sb->s_xattr. That logic changed and now we can simply check whether
the superblock has SB_POSIXACL set and if the inode has
inode->i_{default_}acl set report the appropriate POSIX ACL name.
However, we didn't realize that generic_listxattr() was only ever
used by two filesystems. Both of them don't support POSIX ACLs via
sb->s_xattr handlers and so never reported POSIX ACLs via
generic_listxattr() even if they raised SB_POSIXACL and did contain
inodes which had acls set. The example here is nfs4.
As a result, generic_listxattr() suddenly started reporting POSIX
ACLs when it wouldn't have before. Since SB_POSIXACL implies that the
umask isn't stripped in the VFS nfs4 can't just drop SB_POSIXACL from
the superblock as it would also alter umask handling for them.
So just have generic_listxattr() not report POSIX ACLs as it never
did anyway. It's documented as such.
- Our SB_* flags currently use a signed integer and we shift the last
bit causing UBSAN to complain about undefined behavior. Switch to
using unsigned. While the original patch used an explicit unsigned
bitshift it's now pretty common to rely on the BIT() macro in a lot
of headers nowadays. So the patch has been adjusted to use that.
- Add Namjae as ntfs reviewer. They're already active this cycle so
let's make it explicit right now.

x86/topology: Fix erroneous smp_num_siblings on Intel Hybrid platforms
Traditionally, all CPUs in a system have identical numbers of SMT siblings. That changes with hybrid processors where some logical CPUs have a sibling and others have none. Today, the CPU boot code sets the global variable smp_num_siblings when every CPU thread is brought up. The last thread to boot will overwrite it with the number of siblings of *that* thread. That last thread to boot will "win". If the thread is a Pcore, smp_num_siblings == 2. If it is an Ecore, smp_num_siblings == 1. smp_num_siblings describes if the *system* supports SMT. It should specify the maximum number of SMT threads among all cores. Ensure that smp_num_siblings represents the system-wide maximum number of siblings by always increasing its value. Never allow it to decrease. On MeteorLake-P platform, this fixes a problem that the Ecore CPUs are not updated in any cpu sibling map because the system is treated as an UP system when probing Ecore CPUs. Below shows part of the CPU topology information before and after the fix, for both Pcore and Ecore CPU (cpu0 is Pcore, cpu 12 is Ecore). ... -/sys/devices/system/cpu/cpu0/topology/package_cpus:000fff -/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-11 +/sys/devices/system/cpu/cpu0/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-21 ... -/sys/devices/system/cpu/cpu12/topology/package_cpus:001000 -/sys/devices/system/cpu/cpu12/topology/package_cpus_list:12 +/sys/devices/system/cpu/cpu12/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu12/topology/package_cpus_list:0-21 Notice that the "before" 'package_cpus_list' has only one CPU. This means that userspace tools like lscpu will see a little laptop like an 11-socket system: -Core(s) per socket: 1 -Socket(s): 11 +Core(s) per socket: 16 +Socket(s): 1 This is also expected to make the scheduler do rather wonky things too.

cpufreq: amd-pstate: Update policy->cur in amd_pstate_adjust_perf()
Driver should update policy->cur after updating the frequency.
Currently amd_pstate doesn't update policy->cur when `adjust_perf`
is used. Which causes /proc/cpuinfo to show wrong cpu frequency.
Fix this by updating policy->cur with correct frequency value in
adjust_perf function callback.
- Before the fix: (setting min freq to 1.5 MHz)
[root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
1 cpu MHz : 1777.016
1 cpu MHz : 1797.160
1 cpu MHz : 1797.270
189 cpu MHz : 400.000
- After the fix: (setting min freq to 1.5 MHz)
[root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
1 cpu MHz : 1753.353
1 cpu MHz : 1756.838
