The forward declaration is not needed anymore. The sentence about
"following structs" became obsolete when struct i2c_algorithm became a
kdoc. The paragraph about return values can go because we have this
information in kdoc already.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Define PCIE_RESET_CONFIG_DEVICE_WAIT_MS for the generic 100ms
required after reset before config access (Kevin Xie)
- Define PCIE_T_RRS_READY_MS for the generic 100ms required after
reset before config access (probably should be unified with
PCIE_RESET_CONFIG_DEVICE_WAIT_MS) (Damien Le Moal)
Resource management:
- Rename find_resource() to find_resource_space() to be more
descriptive (Ilpo Järvinen)
- Export find_resource_space() for use by PCI core, which needs to
learn whether there is available space for a bridge window (Ilpo
Järvinen)
- Prevent double counting of resources so window size doesn't grow on
each remove/rescan cycle (Ilpo Järvinen)
- Relax bridge window sizing algorithm so a device doesn't break
simply because it was removed and rescanned (Ilpo Järvinen)
- Evaluate the ACPI PRESERVE_BOOT_CONFIG _DSM in
pci_register_host_bridge() (not acpi_pci_root_create()) so we can
unify it with similar DT functionality (Vidya Sagar)
- Extend use of DT "linux,pci-probe-only" property so it works
per-host bridge as well as globally (Vidya Sagar)
- Unify support for ACPI PRESERVE_BOOT_CONFIG _DSM and the DT
"linux,pci-probe-only" property in pci_preserve_config() (Vidya
Sagar)
Driver binding:

BAR resources (Philipp Stanner)
- Deprecate pcim_iomap_table() because uses like
"pcim_iomap_table()[0]" have no good way to return errors (Philipp
Stanner)

pci_request_region() and similar, which are sometimes managed
depending on whether pcim_enable_device() has been called
previously (Philipp Stanner)
- Reimplement pcim_set_mwi() so it doesn't need to keep store MWI
state (Philipp Stanner)

prevents transactions between functions even though it doesn't
advertise ACS, so the functions can be attached individually via
VFIO (Ajit Khaparde)
Peer-to-peer DMA:

Some hardware need some time to switch from a bus to another. This can
cause the first transfers following the selection of a bus to fail.
There is no way to configure this kind of waiting time in the driver.
Add support for the 'settle-time-us' device-tree property. When set,
the i2c_mux_gpio_select() applies a delay before returning, leaving
enough time to the hardware to switch to the new bus.

Pull i2c fixes from Wolfram Sang:
"The I2C core gains documentation updates for the testunit, a cleanup
regarding unneeded 'driver_data' and more sanity checks in the char
device.
For the host drivers, this release includes significant updates, with
the primary change being the renaming from "master/slave" to
"controller/target" to adhere to I2C v7 and SMBus 3.2 standards.
New Support:
- Added support for Intel Arrow Lake-H
- Added I2C support in the Arioha SoC by linking the Mediatek I2C
controller
Cleanups:
- Added the MODULE_DESCRIPTION() macro, resolving a modpost warning
in the ALi 1563 Southbridge driver.
- Constified the regmap_config declaration in the i2c-designware
driver.
- Improved the coding style in the Renesas R-Car driver by removing
unnecessary semicolons after brackets.
General improvements:
- In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with
RUNTIME_PM_OPS to enable waking up the controller during suspend()
before suspend_noirq() kicks in.
- Improved logging in the Xilinx driver.
- Added a warning (WARN()) in the Renesas R-Car driver for spurious
interrupts.
DTS Changes:
- Removed address-cell and size-cell from the Atmel at91sam, nVidia
Tegra 20, and Samsung S3c2410 devices.
- Fixed Texas Instruments OMAP4 I2C controller to comply with the
i2c-controller.yaml schema.
- Improved indentation in DTS examples for several I2C devices.
- Converted the NXP LPC1788 binding to the dt-schema.
- Added documentation for the compatible string thead,th1520-i2c.
- Added the "power-domains" property for the Meson I2C driver.
AT24 EEPROM driver changes:
- add support for two new Microchip models
- document even more new models in DT bindings (those use fallback
compatibles so no code changes)"

Pull clk updates from Stephen Boyd:
"This a large collection of clk driver updates and a handful of new SoC
clk driver support.
We have the usual Qualcomm clk drivers, along with clk drivers for the
Sophgo and T-Head vendors, all to support some new SoCs.
Nothing in particular stands out to me in the updates. There's the
interconnect clk driver which exposes clks as interconnects, crossing
subsystems. There's a bunch of janitorial things that are improving
drivers in general like kmemdup_array() or fixing error paths. But
overall the updates look normal to fix the description data which is
usually the stuff that's wrong and/or untested.
Core:
- Skip gate basic type KUnit tests on s390 due to lack of MMIO
emulation
New Drivers:
- AP sub-system clock controller in the T-Head TH1520
- Sophgo Sophon sg2042 clk driver
- Qualcomm SM7150 camera, display and video clk drivers
- Qualcomm QCM2290 GPU clk driver
- Qualcomm QCS8386/QCS8084 NSS clk driver
- Qualcomm SM8650 camera and video drivers
Updates:
- Add reset support to Airoha EN7581 clk driver
- Add MODULE_DESCRIPTIONs to various clk drivers
- Introduce helper logic to expose clock controllers as simple
interconnect providers
- Use the interconnect helper above on Qualcomm ipq9574
- Add CLK_SET_RATE_PARENT to the remaining USB pipe clocks on
Qualcomm X1Elite
- Improve error handling in Qualcomm kpss-xcc driver
- Mark Qualcomm SC8280XP LPASS clock controller regmap_config const
- Export more clocks for Rockchip rk3128 peripherals
- Convert Rockchip clk drivers to use kmemdup_array()
- Drop CLK_NR_CLKS from Rockchip rk3128 and rk3188 binding headers
- Make qcom_cc_really_probe() take a struct device to allow reuse in
non-platform-drivers
- Introduce prepare-only branch clock ops in the qcom clk driver to
support clocks on buses that take locks
- Describe parent/child relationship for Qualcomm SC7280 camera GDSCs
- Support Qualcomm Huayra 2290 alpha PLL
- Adjust the highest SDCC clock frequency on Qualcomm IPQ6018 to
match HS200 support
- Add missing PCIe PIPE clocks on Qualcomm IPQ9574
- Fix various configurations and properties in the Qualcomm SA8775P,
X1E80100 and SM7280 drivers
- Park Qualcomm SM8350 GPU RCGs on XO while disabled
- Remove unused CONFIG_QCOM_RPMCC Kconfig symbol
- exynos-clkout: Remove usage of of_device_id table as
.of_match_table, because the driver is instantiated as MFD cell,
not as standalone platform driver. Populated .of_match_table
confused people few times to convert the code to
device_get_match_data(), which broke the driver
- Mark one Samsung UFS clock as critical, because having it off stops
the system from shutdown
- Use kmemdup_array() when applicable
- Remove unused 'struct gates_data' from old sunxi driver library
- Add GPADC clock and reset for Allwinner H616
- Minor Amlogic S4 clock fixes
- DT bindings Yaml conversion of the Amlogic AXG audio controller
- Amlogic C3 clock controllers support
- Amlogic clk flag added to skip init of already enabled PLLs and
avoid relocking
- Amlogic A1 DT bindings updates for system pll support
- Add missing MODULE_DESCRIPTION where necessary
- Remove obsolete clock DT binding header files
- Add Battery Backup (VBATTB) and I2C clocks, resets, and power
domains on Renesas RZ/G3S
- Add audio clocks on Renesas R-Car V4M

The vDSO getrandom() implementation works with a buffer allocated with a
new system call that has certain requirements:
- It shouldn't be written to core dumps.
* Easy: VM_DONTDUMP.
- It should be zeroed on fork.
* Easy: VM_WIPEONFORK.
- It shouldn't be written to swap.
* Uh-oh: mlock is rlimited.
* Uh-oh: mlock isn't inherited by forks.
- It shouldn't reserve actual memory, but it also shouldn't crash when
page faulting in memory if none is available
* Uh-oh: VM_NORESERVE means segfaults.
It turns out that the vDSO getrandom() function has three really nice
characteristics that we can exploit to solve this problem:
1) Due to being wiped during fork(), the vDSO code is already robust to
having the contents of the pages it reads zeroed out midway through
the function's execution.
2) In the absolute worst case of whatever contingency we're coding for,
we have the option to fallback to the getrandom() syscall, and
everything is fine.
3) The buffers the function uses are only ever useful for a maximum of
60 seconds -- a sort of cache, rather than a long term allocation.
These characteristics mean that we can introduce VM_DROPPABLE, which
has the following semantics:
a) It never is written out to swap.
b) Under memory pressure, mm can just drop the pages (so that they're
zero when read back again).
c) It is inherited by fork.
d) It doesn't count against the mlock budget, since nothing is locked.
e) If there's not enough memory to service a page fault, it's not fatal,
and no signal is sent.
This way, allocations used by vDSO getrandom() can use:
VM_DROPPABLE | VM_DONTDUMP | VM_WIPEONFORK | VM_NORESERVE
And there will be no problem with OOMing, crashing on overcommitment,
using memory when not in use, not wiping on fork(), coredumps, or
writing out to swap.
In order to let vDSO getrandom() use this, expose these via mmap(2) as
MAP_DROPPABLE.
Note that this involves removing the MADV_FREE special case from
sort_folio(), which according to Yu Zhao is unnecessary and will simply
result in an extra call to shrink_folio_list() in the worst case. The
chunk removed reenables the swapbacked flag, which we don't want for
VM_DROPPABLE, and we can't conditionalize it here because there isn't a
vma reference available.
Finally, the provided self test ensures that this is working as desired.

The congestion_count was introduced into the struct cgroup by
commit d09d8df3a294 ("blkcg: add generic throttling mechanism"),
but since it is closely related to the blkio subsys, it is not
appropriate to put it in the struct cgroup, so let's move it to
struct blkcg. There should be no functional changes because blkcg
is per cgroup.

Configuration for sbq:
depth=64, wake_batch=6, shift=6, map_nr=1
1. There are 64 requests in progress:
map->word = 0xFFFFFFFFFFFFFFFF
2. After all the 64 requests complete, and no more requests come:
map->word = 0xFFFFFFFFFFFFFFFF, map->cleared = 0xFFFFFFFFFFFFFFFF
3. Now two tasks try to allocate requests:
T1: T2:
__blk_mq_get_tag .
__sbitmap_queue_get .
sbitmap_get .
sbitmap_find_bit .
sbitmap_find_bit_in_word .
__sbitmap_get_word -> nr=-1 __blk_mq_get_tag
sbitmap_deferred_clear __sbitmap_queue_get
/* map->cleared=0xFFFFFFFFFFFFFFFF */ sbitmap_find_bit
if (!READ_ONCE(map->cleared)) sbitmap_find_bit_in_word
return false; __sbitmap_get_word -> nr=-1
mask = xchg(&map->cleared, 0) sbitmap_deferred_clear
atomic_long_andnot() /* map->cleared=0 */
if (!(map->cleared))
return false;
/*
* map->cleared is cleared by T1
* T2 fail to acquire the tag
*/
4. T2 is the sole tag waiter. When T1 puts the tag, T2 cannot be woken
up due to the wake_batch being set at 6. If no more requests come, T1
will wait here indefinitely.
This patch achieves two purposes:
1. Check on ->cleared and update on both ->cleared and ->word need to
be done atomically, and using spinlock could be the simplest solution.
2. Add extra check in sbitmap_deferred_clear(), to identify whether
->word has free bits.

Pull bcachefs updates from Kent Overstreet:
- Metadata version 1.8: Stripe sectors accounting, BCH_DATA_unstriped
This splits out the accounting of dirty sectors and stripe sectors in
alloc keys; this lets us see stripe buckets that still have unstriped
data in them.
This is needed for ensuring that erasure coding is working correctly,
as well as completing stripe creation after a crash.
- Metadata version 1.9: Disk accounting rewrite
The previous disk accounting scheme relied heavily on percpu counters
that were also sharded by outstanding journal buffer; it was fast but
not extensible or scalable, and meant that all accounting counters
were recorded in every journal entry.
The new disk accounting scheme stores accounting as normal btree
keys; updates are deltas until they are flushed by the btree write
buffer.
This means we have no practical limit on the number of counters, and
a new tagged union format that's easy to extend.
We now have counters for compression type/ratio, per-snapshot-id
usage, per-btree-id usage, and pending rebalance work.
- Self healing on read IO/checksum error
Data is now automatically rewritten if we get a read error and then a
successful retry
- Mount API conversion (thanks to Thomas Bertschinger)
- Better lockdep coverage
Previously, btree node locks were tracked individually by lockdep,
like any other lock. But we may take _many_ btree node locks
simultaneously, we easily blow through the limit of 48 locks that
lockdep can track, leading to lockdep turning itself off.
Tracking each btree node lock individually isn't really necessary
since we have our own cycle detector for deadlock avoidance and
centralized tracking of btree node locks, so we now have a single
lockdep_map in btree_trans for "any btree nodes are locked".
- Some more small incremental work towards online check_allocations
- Lots more debugging improvements
- Fixes, including:
- undefined behaviour fixes, originally noted as breaking userspace
LTO builds
- fix a spurious warning in fsck_err, reported by Marcin
- fix an integer overflow on trans->nr_updates, also reported by
Marcin; this broke during deletion of highly fragmented indirect

Pull slab updates from Vlastimil Babka:
"The most prominent change this time is the kmem_buckets based
hardening of kmalloc() allocations from Kees Cook.
We have also extended the kmalloc() alignment guarantees for
non-power-of-two sizes in a way that benefits rust.
The rest are various cleanups and non-critical fixups.
- Dedicated bucket allocator (Kees Cook)
This series [1] enhances the probabilistic defense against heap
spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year.
kmalloc() users that are known to be useful for exploits can get
completely separate set of kmalloc caches that can't be shared with
other users. The first converted users are alloc_msg() and
memdup_user().
The hardening is enabled by CONFIG_SLAB_BUCKETS.
- Extended kmalloc() alignment guarantees (Vlastimil Babka)
For years now we have guaranteed natural alignment for power-of-two
allocations, but nothing was defined for other sizes (in practice,
we have two such buckets, kmalloc-96 and kmalloc-192).
To avoid unnecessary padding in the rust layer due to its alignment
rules, extend the guarantee so that the alignment is at least the
largest power-of-two divisor of the requested size.
This fits what rust needs, is a superset of the existing
power-of-two guarantee, and does not in practice change the layout
(and thus does not add overhead due to padding) of the kmalloc-96
and kmalloc-192 caches, unless slab debugging is enabled for them.
- Cleanups and non-critical fixups (Chengming Zhou, Suren
Baghdasaryan, Matthew Willcox, Alex Shi, and Vlastimil Babka)
Various tweaks related to the new alloc profiling code, folio
conversion, debugging and more leftovers after SLAB"

Pull ftrace updates from Steven Rostedt:
"Rewrite of function graph tracer to allow multiple users
Up until now, the function graph tracer could only have a single user
attached to it. If another user tried to attach to the function graph
tracer while one was already attached, it would fail. Allowing
function graph tracer to have more than one user has been asked for
since 2009, but it required a rewrite to the logic to pull it off so
it never happened. Until now!
There's three systems that trace the return of a function. That is
kretprobes, function graph tracer, and BPF. kretprobes and function
graph tracing both do it similarly. The difference is that kretprobes
uses a shadow stack per callback and function graph tracer creates a
shadow stack for all tasks. The function graph tracer method makes it
possible to trace the return of all functions. As kretprobes now needs
that feature too, allowing it to use function graph tracer was needed.
BPF also wants to trace the return of many probes and its method
doesn't scale either. Having it use function graph tracer would
improve that.
By allowing function graph tracer to have multiple users allows both
kretprobes and BPF to use function graph tracer in these cases. This
will allow kretprobes code to be removed in the future as it's version
will no longer be needed.
Note, function graph tracer is only limited to 16 simultaneous users,
due to shadow stack size and allocated slots"

Now that the platform MSI hack is gone, nothing needs to know about struct
msi_device_data outside of the core code.

Most ARM(64) PCI/MSI domains mask and unmask in the parent domain after or
before the PCI mask/unmask operation takes place. So there are more than a
dozen of the same wrapper implementation all over the place.
Don't make the same mistake with the new per device PCI/MSI domains and
provide a new MSI feature flag, which lets the domain implementation
enable this sequence in the PCI/MSI code.

Several versions of GCC mis-compile asm goto with outputs. We try to
workaround this, but our workaround is demonstrably incomplete and
liable to result in subtle bugs, especially on arm64 where get_user()
has recently been moved over to using asm goto with outputs.
From discussion(s) with Linus at:
https://lore.kernel.org/linux-arm-kernel/Zpfv2tnlQ-gOLGac@J2N7QTR9R3.cambridge.arm.com/
https://lore.kernel.org/linux-arm-kernel/ZpfxLrJAOF2YNqCk@J2N7QTR9R3.cambridge.arm.com/
... it sounds like the best thing to do for now is to remove the
workaround and make CC_HAS_ASM_GOTO_OUTPUT depend on working compiler
versions.
The issue was originally reported to GCC by Sean Christopherson:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113921
... and Jakub Jelinek fixed this for GCC 14, with the fix backported to
13.3.0, 12.4.0, and 11.5.0.
In the kernel, we tried to workaround broken compilers in commits:
4356e9f841f7 ("work around gcc bugs with 'asm goto' with outputs")
68fb3ca0e408 ("update workarounds for gcc "asm goto" issue")
... but the workaround of adding an empty asm("") after the asm volatile
goto(...) demonstrably does not always avoid the problem, as can be seen
in the following test case:
| #define asm_goto_output(x...) \
| do { asm volatile goto(x); asm (""); } while (0)
|
| #define __good_or_bad(__val, __key) \
| do { \
| __label__ __failed; \
| unsigned long __tmp; \
| asm_goto_output( \
| " cbnz %[key], %l[__failed]\n" \
| " mov %[val], #0x900d\n" \
| : [val] "=r" (__tmp) \
| : [key] "r" (__key) \
| : \
| : __failed); \
| (__val) = __tmp; \
| break; \
| __failed: \
| (__val) = 0xbad; \
| } while (0)
|
| unsigned long get_val(unsigned long key);
| unsigned long get_val(unsigned long key)
| {
| unsigned long val = 0xbad;
|
| __good_or_bad(val, key);
|
| return val;
| }
GCC 13.2.0 (at -O2) compiles this to:
| cbnz x0, .Lfailed
| mov x0, #0x900d
| .Lfailed:
| ret
GCC 14.1.0 (at -O2) compiles this to:
| cbnz x0, .Lfailed
| mov x0, #0x900d
| ret
| .Lfailed:
| mov x0, #0xbad
| ret
Note that GCC 13.2.0 erroneously omits the assignment to 'val' in the
error path (even though this does not depend on an output of the asm
goto). GCC 14.1.0 correctly retains the assignment.
This problem can be seen within the kernel with the following test case:
| #include <linux/uaccess.h>
| #include <linux/types.h>
|
| noinline unsigned long test_unsafe_get_user(unsigned long __user *ptr);
| noinline unsigned long test_unsafe_get_user(unsigned long __user *ptr)
| {
| unsigned long val;
|
| unsafe_get_user(val, ptr, Efault);
| return val;
|
| Efault:
| val = 0x900d;
| return val;
| }
GCC 13.2.0 (arm64 defconfig) compiles this to:
| and x0, x0, #0xff7fffffffffffff
| ldtr x0, [x0]
| .Lextable_fixup:
| ret
GCC 13.2.0 (x86_64 defconfig + MITIGATION_RETPOLINE=n) compiles this to:
| endbr64
| mov (%rdi),%rax
| .Lextable_fixup:
| ret
... omitting the assignment to 'val' in the error path, and leaving
garbage in the result register returned by the function (which happens
to contain the faulting address in the generated code).
GCC 14.1.0 (arm64 defconfig) compiles this to:
| and x0, x0, #0xff7fffffffffffff
| ldtr x0, [x0]
| ret
| .Lextable_fixup:
| mov x0, #0x900d // #36877
| ret
GCC 14.1.0 (x86_64 defconfig + MITIGATION_RETPOLINE=n) compiles this to:
| endbr64
| mov (%rdi),%rax
| ret
| .Lextable_fixup:
| mov $0x900d,%eax
| ret
... retaining the expected assignment to 'val' in the error path.
We don't have a complete and reasonable workaround. While placing empty
asm("") blocks after each goto label *might* be sufficient, we don't
know for certain, this is tedious and error-prone, and there doesn't
seem to be a neat way to wrap this up (which is especially painful for
cases with multiple goto labels).
Avoid this issue by disabling CONFIG_CC_HAS_ASM_GOTO_OUTPUT for
known-broken compiler versions and removing the workaround (along with
the CONFIG_GCC_ASM_GOTO_OUTPUT_WORKAROUND config option).
For the moment I've left the default implementation of asm_goto_output()
unchanged. This should now be redundant since any compiler with the fix
for the clobbering issue whould also have a fix for the (earlier)
volatile issue, but it's far less churny to leave it around, which makes
it easier to backport this patch if necessary.
