The TI_K3_M4_REMOTEPROC Kconfig entry selects OMAP2PLUS_MBOX, but that
driver in turn depends on other things, which the k4-m4 driver didn't.
This causes a Kconfig time warning:
WARNING: unmet direct dependencies detected for OMAP2PLUS_MBOX
Depends on [n]: MAILBOX [=y] && (ARCH_OMAP2PLUS || ARCH_K3)
Selected by [m]:
- TI_K3_M4_REMOTEPROC [=m] && REMOTEPROC [=y] && (ARCH_K3 || COMPILE_TEST [=y])
because you can't select something that is unavailable.
Make the dependencies for TI_K3_M4_REMOTEPROC match those of the
OMAP2PLUS_MBOX driver that it needs.

Pull more io_uring updates from Jens Axboe:
"Mostly just a set of fixes in here, or little changes that didn't get
included in the initial pull request. This contains:
- Move the SQPOLL napi polling outside the submission lock (Olivier)
- Rename of the "copy buffers" API that got added in the 6.12 merge
window. There's really no copying going on, it's just referencing
the buffers. After a bit of consideration, decided that it was
better to simply rename this to avoid potential confusion (me)
- Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
start + len tracking rather than having start / end in there, and
by removing the caching of folio_mask when we can just calculate it
from folio_shift when we need it (me)
- Fixes for the SQPOLL affinity checking (me, Felix)
- Fix for how cqring waiting checks for the presence of task_work.
Just check it directly rather than check for a specific
notification mechanism (me)
- Tweak to how request linking is represented in tracing (me)
- Fix a syzbot report that deliberately sets up a huge list of
overflow entries, and then hits rcu stalls when flushing this list.
Just check for the need to preempt, and drop/reacquire locks in the
loop. There's no state maintained over the loop itself, and each
entry is yanked from head-of-list (me)"

It was observed that issuing the ABORT bit (IC_ENABLE[1]) will not
work when IC_ENABLE is already disabled.
Check if the ENABLE bit (IC_ENABLE[0]) is disabled when the controller
is holding SCL low. If the ENABLE bit is disabled, the software needs
to enable it before trying to issue the ABORT bit. otherwise,
the controller ignores any write to ABORT bit.
These kernel logs show up whenever an I2C transaction is
attempted after this failure.

One of concerns for enabling TOMOYO in prebuilt kernels is that distributor
wants to avoid bloating kernel packages. Although boot-time kernel command
line options allows selecting built-in LSMs to enable, file size increase
of vmlinux and memory footprint increase of vmlinux caused by builtin-but-
not-enabled LSMs remains. If it becomes possible to make LSMs dynamically
appendable after boot using loadable kernel modules, these problems will
go away.
Another of concerns for enabling TOMOYO in prebuilt kernels is that who can
provide support when distributor cannot provide support. Due to "those who
compiled kernel code is expected to provide support for that kernel code"
spell, TOMOYO is failing to get enabled in Fedora distribution [1]. The
point of loadable kernel module is to share the workload. If it becomes
possible to make LSMs dynamically appendable after boot using loadable
kernel modules, as with people can use device drivers not supported by
distributors but provided by third party device vendors, we can break
this spell and can lower the barrier for using TOMOYO.
This patch is intended for demonstrating that there is nothing difficult
for supporting TOMOYO-like loadable LSM modules. For now we need to live
with a mixture of built-in part and loadable part because fully loadable
LSM modules are not supported since Linux 2.6.24 [2] and number of LSMs
which can reserve static call slots is determined at compile time in
Linux 6.12.
Major changes in this patch are described below.
There are no behavior changes as long as TOMOYO is built into vmlinux.
Add CONFIG_SECURITY_TOMOYO_LKM as "bool" instead of changing
CONFIG_SECURITY_TOMOYO from "bool" to "tristate", for something went
wrong with how Makefile is evaluated if I choose "tristate".
Add proxy.c for serving as a bridge between vmlinux and tomoyo.ko .
Move callback functions from init.c to proxy.c when building as a loadable
LSM module. init.c is built-in part and remains for reserving static call
slots. proxy.c contains module's init function and tells init.c location of
callback functions, making it possible to use static call for tomoyo.ko .
By deferring initialization of "struct tomoyo_task" until tomoyo.ko is
loaded, threads created between init.c reserved LSM hooks and proxy.c
updates LSM hooks will have NULL "struct tomoyo_task" instances. Assuming
that tomoyo.ko is loaded by the moment when the global init process starts,
initialize "struct tomoyo_task" instance for current thread as a kernel
thread when tomoyo_task(current) is called for the first time.
There is a hack for exporting currently not-exported functions.
This hack will be removed after all relevant functions are exported.

syzbot reported a WARNING in bond_xdp_get_xmit_slave. To reproduce
this[1], one bond device (bond1) has xdpdrv, which increases
bpf_master_redirect_enabled_key. Another bond device (bond0) which is
unsupported by XDP but its slave (veth3) has xdpgeneric that returns
XDP_TX. This triggers WARN_ON_ONCE() from the xdp_master_redirect().
To reduce unnecessary warnings and improve log management, we need to
delete the WARN_ON_ONCE() and add ratelimit to the netdev_err().
[1] Steps to reproduce:
# Needs tx_xdp with return XDP_TX;
ip l add veth0 type veth peer veth1
ip l add veth3 type veth peer veth4
ip l add bond0 type bond mode 6 # BOND_MODE_ALB, unsupported by XDP
ip l add bond1 type bond # BOND_MODE_ROUNDROBIN by default
ip l set veth0 master bond1
ip l set bond1 up
# Increases bpf_master_redirect_enabled_key
ip l set dev bond1 xdpdrv object tx_xdp.o section xdp_tx
ip l set veth3 master bond0

As Christophe pointed out, tuning the chacha implementation by
scheduling the instructions like what GCC does can improve the
performance.
The tuning does not introduce too much complexity (basically it's just
reordering some instructions). And the tuning does not hurt readibility
too much: actually the tuned code looks even more similar to a
textbook-style implementation based on 128-bit vectors. So overall it's
a good deal to me.
Tested with vdso_test_getchacha and benched with vdso_test_getrandom.
On a LA664 the speedup is 5%, and I expect a larger speedup on LA[2-4]64
with a lower issue rate.

Paul Barker says:
====================
Fix maximum TX/RX frame sizes in ravb driver
These patches fix a couple of bugs in the maximum supported TX/RX frame
sizes in the ravb driver.
* For the GbEth IP, we were advertising a maximum TX frame size/MTU
that was larger that the maximum the hardware can transmit.
* For the R-Car AVB IP, we were unnecessarily setting the maximum RX
frame size/MRU based on the MTU, which by default is smaller than
the maximum the hardware can receive.
For the R-Car AVB IP, the maximum TX frame size should be 2047 (not
2048), but additional work will be required to validate that change so
it is not included in this series.
Changes v2->v3:
* Pick up Reviewed-by tag and suggested comment improvement from
Niklas.
Changes v1->v2:
* Rebase on net tree as these are both bugfixes.
* Pick up Reviewed-by tags.

The datasheets for all SoCs using the GbEth IP specify a maximum
transmission frame size of 1.5 kByte. I've confirmed through internal

allows us to support the default MTU of 1500 bytes after reserving space
for the Ethernet header, frame checksums and an optional VLAN tag.

The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider
when offload is disabled") allows the "port_transmit_rate_kbps" to be
set to a value of 0, which is then passed to the "div_s64" function when
tc-cbs is disabled. This leads to a zero-division error.
When tc-cbs is disabled, the idleslope, sendslope, and credit values the
credit values are not required to be configured. Therefore, adding a return
statement after setting the txQ mode to DCB when tc-cbs is disabled would
prevent a zero-division error.

When broadcasting data to multiple nodes via MHI, using skb_clone()
causes all nodes to receive the same header data. This can result in
packets being discarded by endpoints, leading to lost data.
This issue occurs when a socket is closed, and a QRTR_TYPE_DEL_CLIENT
packet is broadcasted. All nodes receive the same destination node ID,
causing the node connected to the client to discard the packet and
remain unaware of the client's deletion.
Replace skb_clone() with pskb_copy(), to create a separate copy of
the header for each sk_buff.

ata_msense_control_spgt2() can be called even for devices that do not
support CDL when the user requests the ALL_SUB_MPAGES mode sense page,
but for such device, this will cause a NULL pointer dereference as
dev->cdl is NULL. Similarly, we should not return any data if
ata_msense_control_spgt2() is called when the user requested the
CDL_T2A_SUB_MPAGE or CDL_T2B_SUB_MPAGE pages for a device that does not
support CDL.
Avoid this potential NULL pointer dereference by checking if the device
support CDL on entry to ata_msense_control_spgt2() and return 0 if it
does not support CDL.

Now _percpu_read() and _percpu_write() macros call __percpu_read()
and __percpu_write() static inline functions that result in a single
assembly instruction. However, percpu infrastructure expects its leaf
definitions to encode the size of their percpu variable, so the patch
merges all the asm clauses from the static inline function into the
corresponding leaf macros.
The secondary effect of this change is to avoid explicit __percpu
annotations for function arguments. Currently, __percpu macro is defined
in include/linux/compiler_types.h, but with proposed patch [1], __percpu
definition will need macros from include/asm-generic/percpu.h, creating
forward dependency loop.
The proposed solution is the same as x86 architecture uses.

LoongArch has similar problems explained in commit 7f0b1bf04511348995d6
("arm64: Fix barriers used for page table modifications"), when hardware
page table walker (PTW) enabled, speculative accesses may cause spurious
page fault in kernel space. Theoretically, in order to completely avoid
spurious page fault we need a "dbar + ibar" pair between the page table
modifications and the subsequent memory accesses using the corresponding
virtual address. But "ibar" is too heavy for performace, so we only use
a "dbar 0b11000" in set_pte(). And let spurious_fault() filter the rest
rare spurious page faults which should be avoided by "ibar".
Besides, we replace the llsc loop with amo in set_pte() which has better
performace, and refactor mmu_context.h to 1) avoid any load/store/branch
instructions between the writing of CSR.ASID & CSR.PGDL, 2) ensure flush
tlb operation is after updating ASID.

Probe ISA level, TLB, IOCSR information from CPUCFG to improve kernel
resilience to different core implementations.
BTW, IOCSR register definition appears to be a platform-specific spec
instead of an architecture spec, even for the Loongson CPUs there is no

Thus it's dangerous to perform IOCSR probing without checking CPU type

Currently, many architectures support generic CPU vulnerabilites, such

commit 61ae1321f06c ("arm64: enable generic CPU vulnerabilites support")
commit 0e3f3649d44b ("riscv: Enable generic CPU vulnerabilites support")
All LoongArch CPUs (since Loongson-3A5000) implement a special mechanism
in the processor core to prevent "Meltdown" and "Spectre" attacks, so it
can enable generic CPU vulnerabilites support for LoongArch too.
Without this patch, there are no user interfaces of vulnerabilities to
check on LoongArch. The output of those files reflects the state of the
CPUs in the system, the output value "Not affected" means "CPU is not
