i2c: rust: mark I2cAdapter methods as inline
A single cleanup for the Rust I2C abstractions, targeting 7.3.
`I2cAdapter::get`, `inc_ref`, and `dec_ref` are trivial wrappers around
`i2c_get_adapter`/`i2c_put_adapter` and were showing up as their own
symbols in the build. Mark them `#[inline]` so they get folded into
their callers instead.

i2c: rust: mark I2cAdapter methods as inline
|
|
When building the kernel using llvm-19.1.7-rust-1.85.0-x86_64, the
following symbols are generated:
$ nm vmlinux | grep ' _R'.*I2cAdapter | rustfilt
ffffffff817ff380 T <kernel::i2c::I2cAdapter>::get
ffffffff817ff400 T <kernel::i2c::I2cAdapter as kernel::sync::aref::AlwaysRefCounted>::dec_ref
ffffffff817ff3e0 T <kernel::i2c::I2cAdapter as kernel::sync::aref::AlwaysRefCounted>::inc_ref
However, these Rust symbols are trivial wrappers around the
`i2c_get_adapter` and `i2c_put_adapter` functions. It doesn't make sense
to go through a trivial wrapper for these functions.

Sync common.bpf.h, compat.bpf.h and compat.h with the scx repo, which
accumulated the following:
- __COMPAT_read_enum() can now recover 64-bit scx enum values from kernel
BTF generated without BTF_KIND_ENUM64 support (pahole < 1.24 or
--skip_encoding_btf_enum64, e.g. COS/GKE kernels), substituting values
from the build-time vmlinux.h cross-checked against the low 32 bits the
kernel does provide.
- is_migration_disabled() no longer assumes the BPF prolog always disables
migration. Since 8e4f0b1ebcf2 ("bpf: use rcu_read_lock_dont_migrate() for
trampoline.c") the prolog only does so under CONFIG_PREEMPT_RCU, so the
old current-task test under-reported on v6.18+ !PREEMPT_RCU kernels. A
runtime probe on bpf_scx_reg() handles older kernels with backported
trampoline behavior.
- __COMPAT_scx_bpf_dsq_peek() is gated behind kernel v7.1 where 2f2ea7709266
("sched_ext: Use dsq->first_task instead of list_empty() in
dispatch_enqueue() FIFO-tail") fixed the kfunc spuriously returning NULL
on non-empty FIFO DSQs, and the new
scx_bpf_reenqueue_local_from_anywhere() provides a callable-from-anywhere
reenqueue which prefers the generic scx_bpf_dsq_reenq(). Both were first
posted by Gavin Guo and Changwoo Min and are picked up here with the
review feedback folded in.
- __COMPAT_scx_bpf_cpu_curr() and the scx_bpf_cpu_rq() declaration are
restored. Schedulers built from these headers still run on pre-v6.18
kernels where scx_bpf_cpu_curr() does not resolve and the scx_bpf_cpu_rq()
fallback still exists.
- scx_clock_task() and scx_clock_pelt() document their stale-read behavior
for remote idle CPUs under NO_HZ_IDLE.

Regenerate enum_defs.autogen.h against the current tree, picking up the
dispatch verdict enums and dropping the marker for the removed
SCX_RQ_IN_BALANCE. Add enums_abi.autogen.h, a table of 64-bit scx enumerator
values generated from vmlinux.h, used as the substitution source when the
running kernel's BTF truncates 64-bit enum values to 32 bits.

F2FS writes long symlink data with page_symlink() and then flushes the
symlink mapping to reduce the chance of exposing a broken symlink.
That flush result is currently ignored. If the writeback fails, symlink()
still returns success even though the symlink is not durable and the same
operation can already surface -EIO through syncfs().
Return the writeback error to userspace and skip the dirsync flush once the
symlink data flush has failed.

In f2fs_rename() and f2fs_unlink(), directly returning -EPERM when
encountering a device aliasing file bypasses the cleanup path.
Fix this by setting err to -EPERM and jumping to the proper cleanup
labels (out_dir and out) instead of returning immediately.

SND_MPC52xx_SOC_PCM030 and SND_MPC52xx_SOC_EFIKA both select
SND_SOC_MPC5200_AC97 without ensuring its dependency on PPC_BESTCOMM is
met. This causes unmet dependencies such as:
WARNING: unmet direct dependencies detected for SND_SOC_MPC5200_AC97
Depends on [n]: SOUND [=m] && SND [=m] && SND_SOC [=m] && SND_POWERPC_SOC [=m] && PPC_BESTCOMM [=n]

In v1, Rosen pointed out that the import of "mpc5200_dma.h" is actually
unnecessary, and Arnd suggested that the 'select' of SND_SOC_MPC5200_AC97
be changed to 'depends on'.
This resolves all 3 unmet dependencies.
These unmet dependency bugs were detected by kconfirm, a static analysis tool
for Kconfig.

* At boot time, when the registers are accessed by asoc
layer while trying to enable a DAPM path, while the device
is still being attached, -EBUSY error will be thown by
regmap_read and regmap_udpate_bits. Because the regmap will
be in cache only mode. Add default values for these registers
so that, the cached values are returned instead of error.
* Also remove writing default values once again for first
attach.

Rename gain and volume macros to match the hardware intent. Currently,
both TAC_SDCA_CHANNEL_GAIN and TAC_SDCA_CHANNEL_VOLUME are defined as 0x02.
Keep only TAC_SDCA_CHANNEL_VOLUME and reposition TAC_SDCA_CHANNEL_GAIN to
0x0B. Remove the now-redundant TAC_SDCA_MASTER_GAIN alias (also 0x0B),
replacing its single use with TAC_SDCA_CHANNEL_GAIN.

- Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we do for
other config space accessors (Krzysztof Wilczyński)
- Tidy static resource attribute names and macros that build them
(Krzysztof Wilczyński)
* pci/sysfs:
PCI/sysfs: Add legacy I/O and memory attribute macros

PCI/sysfs: Add pci_ prefix to static PCI resource attribute names
PCI/sysfs: Add lockdown checks to legacy I/O and memory handlers
PCI/sysfs: Return -EINVAL for unsupported I/O BAR mmap

- Add hotplug reservation only once (not at each level of the hierarchy) so
bridge windows don't grow more than necessary (Ilpo Järvinen)
* pci/resource:
PCI: Do not add hotplug reservation multiple times

- Take a reference on the I2C adapter in tc9563 to avoid uninterruptible
hang when unloading an I2C module while in-use (Johan Hovold)
- Restrict tc9563 Tx Amplitude, DFE and N_FTS to USP, DSP1 and DSP2 in DT
binding (Manivannan Sadhasivam)
- Fix parsing tc9563 integrated Ethernet MAC Endpoint node (Manivannan
Sadhasivam)
- Power off only tc9563 external-facing ports (DSP1, DSP2), leaving USP and
DSP3 powered up (Manivannan Sadhasivam)
- Skip tc9563 Tx amplitude and DFE tuning for DSP3, which don't support
them (Manivannan Sadhasivam)
- Move integrated MAC Endpoint out of the list of internal ports and
configure it separately (Manivannan Sadhasivam)
* pci/pwrctrl:
PCI/pwrctrl: tc9563: Move Integrated MAC Endpoint out of 'tc9563_pwrctrl_ports' enum
PCI/pwrctrl: tc9563: Rename DSP3 to VDSP
PCI/pwrctrl: tc9563: Skip Tx amplitude and DFE tuning for DSP3
PCI/pwrctrl: tc9563: Power off only the external ports in tc9563_pwrctrl_disable_port()

- Avoid spurious runtime PM wakeup on config space accesses that are
outside config space and fail before reaching PCI (Krzysztof Wilczyński)
- Warn on user-space writes to kernel-exclusive config space regions, as we
already do for sysfs (Krzysztof Wilczyński)
- Check credentials of opener, not reader, for config space reads, as we
already to for sysfs (Krzysztof Wilczyński)
* pci/procfs:
PCI/proc: Use file_ns_capable() when checking config space read access
PCI/proc: Warn on writes to kernel-exclusive config space regions
PCI/proc: Avoid spurious runtime PM wakeup on config space accesses

- Allow probing even without child services so it can do power management
(Brian Norris)
* pci/portdrv:
PCI/portdrv: Allow probing even without child services

- Allow D3 for native hotplug-capable Root Ports on non-x86 platforms (we
avoid D3 for these ports on x86 because some old platforms didn't
validate it) (Manivannan Sadhasivam)
* pci/pm:
PCI: Allow D3 for native hotplug-capable Root Ports on non-x86 platforms

- Add Nvidia Vera Rubin to list of platforms that support P2PDMA (Leon
Romanovsky)
* pci/p2pdma:
PCI/P2PDMA: Add Nvidia Vera Rubin to whitelist

- Pass empty string, not an uninitialized device_class string, to
acpi_bus_generate_netlink_event(), so we can remove device_class
completely in the future (Rafael J. Wysocki)
* pci/hotplug:
PCI: acpiphp_ibm: Do not use uninitialized device_class

- Don't store pci_device_id in agp amd-k7 and via, ata, scsi nsp32, ipack
tpci200, mlxsw since the dynamic ID feature means the ID is only
guaranteed to live during probe (Gary Guo)
- Add pci_match_one_id() to match an ID directly so dynamic ID insertion
doesn't need to make a temporary device for matching (Gary Guo)
- Check for existing ID inside the dynamic ID addition critical section to
avoid a time-of-check vs time-of-use race (Gary Guo)
- Copy device ID to avoid use-after-free when match races with sysfs
dynamic ID removal (Gary Guo)
* pci/enumeration:
PCI: Fix UAF when probe runs concurrent to dyn ID removal
PCI: Fix dyn_id add TOCTOU
PCI: Make pci_match_one_device() match on ID instead of device
agp/amd-k7: Don't rely on address of pci_device_id
agp/via: Don't rely on address of pci_device_id
mlxsw: pci: Don't store pci_device_id
ipack: tpci200: Don't store pci_device_id
