not clear what we should use here, but in general using 'depends on'
causes fewer problems, so use that.

Callers of flowi4_update_output() never try to update ->flowi4_tos:
* ip_route_connect() updates ->flowi4_tos with its own current
value.
* ip_route_newports() has two users: tcp_v4_connect() and
dccp_v4_connect. Both initialise fl4 with ip_route_connect(), which
in turn sets ->flowi4_tos with RT_TOS(inet_sk(sk)->tos) and
->flowi4_scope based on SOCK_LOCALROUTE.
Then ip_route_newports() updates ->flowi4_tos with
RT_CONN_FLAGS(sk), which is the same as RT_TOS(inet_sk(sk)->tos),
unless SOCK_LOCALROUTE is set on the socket. In that case, the
lowest order bit is set to 1, to eventually inform
ip_route_output_key_hash() to restrict the scope to RT_SCOPE_LINK.
This is equivalent to properly setting ->flowi4_scope as
ip_route_connect() did.
* ip_vs_xmit.c initialises ->flowi4_tos with memset(0), then calls
flowi4_update_output() with tos=0.
* sctp_v4_get_dst() uses the same RT_CONN_FLAGS_TOS() when
initialising ->flowi4_tos and when calling flowi4_update_output().
In the end, ->flowi4_tos never changes. So let's just drop the tos
parameter. This will simplify the conversion of ->flowi4_tos from __u8
to dscp_t.

For ARM defconfig (i.e. multi_v7_defconfig), modpost fails to detect
some types of section mismatches.
[test code]
#include <linux/init.h>
int __initdata foo;
int get_foo(void) { return foo; }
It is apparently a bad reference, but modpost does not report anything.
The test code above produces the following relocations.
Relocation section '.rel.text' at offset 0x200 contains 2 entries:
Offset Info Type Sym.Value Sym. Name
00000000 0000062b R_ARM_MOVW_ABS_NC 00000000 .LANCHOR0
00000004 0000062c R_ARM_MOVT_ABS 00000000 .LANCHOR0
Currently, R_ARM_MOVW_ABS_NC and R_ARM_MOVT_ABS are just skipped.
Add code to handle them. I checked arch/arm/kernel/module.c to learn
how the offset is encoded in the instruction.
The referenced symbol in relocation might be a local anchor.
If is_valid_name() returns false, let's search for a better symbol name.

The reference from 'get_bar' to 'foo' seems wrong.
I have no solution for this because it is true in assembly level.

the offset to 'bar' is encoded in the instruction 'r0, [r3, #4]'.

When find_elf_symbol() gets into a situation where relsym->st_name is
zero, there is no guarantee to get the symbol name as written in C.

The .L-prefixed exception handling symbols of get_user() and put_user()
do get discarded from the symbol table of the final kernel image.
This confuses tools which parse that symbol table and try to map the
chunk of code to a symbol. And, in general, from toolchain perspective,
it is a good practice to have all code belong to a symbol, and the
correct one at that.
( Currently, objdump displays that exception handling chunk as part
of the previous symbol which is a "fallback" of sorts and not
correct. )
While at it, rename them to something more descriptive.

Allow API users of kmem_cache_create to specify that they don't want
any slab merge or aliasing (with similar sized objects). Use this in
kfence_test.
The SKB (sk_buff) kmem_cache slab is critical for network performance.
Network stack uses kmem_cache_{alloc,free}_bulk APIs to gain
performance by amortising the alloc/free cost.
For the bulk API to perform efficiently the slub fragmentation need to
be low. Especially for the SLUB allocator, the efficiency of bulk free
API depend on objects belonging to the same slab (page).
When running different network performance microbenchmarks, I started
to notice that performance was reduced (slightly) when machines had
longer uptimes. I believe the cause was 'skbuff_head_cache' got
aliased/merged into the general slub for 256 bytes sized objects (with
my kernel config, without CONFIG_HARDENED_USERCOPY).
For SKB kmem_cache network stack have reasons for not merging, but it
varies depending on kernel config (e.g. CONFIG_HARDENED_USERCOPY).
We want to explicitly set SLAB_NO_MERGE for this kmem_cache.
Another use case for the flag has been described by David Sterba [1]:
> This can be used for more fine grained control over the caches or for
> debugging builds where separate slabs can verify that no objects leak.
> The slab_nomerge boot option is too coarse and would need to be
> enabled on all testing hosts. There are some other ways how to disable
> merging, e.g. a slab constructor but this disables poisoning besides
> that it adds additional overhead. Other flags are internal and may
> have other semantics.
> A concrete example what motivates the flag. During 'btrfs balance'
> slab top reported huge increase in caches like
> 1330095 1330095 100% 0.10K 34105 39 136420K Acpi-ParseExt

The .data field in struct of_device_id is used as a const member so it's
inappropriate to attach struct s32_pinctrl_soc_info with of_device_id
because some members in s32_pinctrl_soc_info need to be filled by
pinctrl-s32cc at runtime.
For this reason, struct s32_pinctrl_soc_info must be allocated in
pinctrl-s32cc and then create a new struct s32_pinctrl_soc_data in order
to represent const .data in of_device_id. To combine these two structures,
a s32_pinctrl_soc_data pointer is introduced in s32_pinctrl_soc_info.
Besides, use of_device_get_match_data() instead of of_match_device() since
the driver only needs to retrieve the .data from of_device_id.

In addition to properly handling probe deferrals dev_err_probe()
conveniently combines printing an error message with returning
the errno. So let's use it for every error path in rtl_init_one()
to simplify the code.

Oleksij Rempel says:
====================
Extend dt-bindings for PSE-PD controllers and update prtt1c dts
This patch set comes in response to issues identified while adding PoDL
PSE support to the stm32 prtt1c device tree. The existing pse-pd device
tree bindings did not allow node name patterns like "ethernet-pse-0" and
"ethernet-pse-1", leading to validation failures.
To address these false positives in validation, the device tree bindings
are extended to support these node name patterns. Alongside this, an
example node is added to aid in the improved validation process.

In the offending fixes commit I mistakenly removed the reply message of
the port new command. I was under impression it is a new port
notification, partly due to the "notify" in the name of the helper
function. Bring the code sending reply with new port message back, this
time putting it directly to devlink_nl_cmd_port_new_doit()

After the blamed commit, the member key is longer 4-byte aligned. On
platforms that do not support unaligned access, e.g., MIPS32R2 with
unaligned_action set to 1, this will trigger a crash when accessing
an IPv6 pneigh_entry, as the key is cast to an in6_addr pointer.
Change the type of the key to u32 to make it aligned.

We need to avoid inconsistencies across the PTEs that form a NAPOT
region, so when we write protect such a region, we should clear and flush
all the PTEs to make sure that any of those PTEs is not cached which would
result in such inconsistencies (arm64 does the same).

The warning is pointing out that while 'enum i915_cache_level' and
'unsigned int' are ABI compatible, these indirect calls will fail
clang's kernel Control Flow Integrity (kCFI) checks, as the callback's
signature does not exactly match the prototype's signature.
To fix this, replace the cache_level parameter with pat_index, as was
done in other places within i915 where there is no difference between
cache_level and pat_index on certain generations.

When booting a kernel compiled with CONFIG_CFI_CLANG (kCFI), there is a
CFI failure in ggtt_probe_common() when trying to call hsw_pte_encode()
via an indirect call:
[ 5.030027] CFI failure at ggtt_probe_common+0xd1/0x130 [i915] (target: hsw_pte_encode+0x0/0x30 [i915]; expected type: 0xf5c1d0fc)
With kCFI, indirect calls are validated against their expected type
versus actual type and failures occur when the two types do not match.
clang's -Wincompatible-function-pointer-types-strict can catch this at
compile time but it is not enabled for the kernel yet:

In this case, the pre-gen8 pte_encode functions have a second parameter
type of 'enum i915_cache_level' whereas the function pointer prototype
in 'struct i915_address_space' expects a second parameter type of
'unsigned int'.
Update the second parameter of the callbacks and the comment above them
noting that these statements are still valid, which matches other
functions and files, to clear up the kCFI failures at run time.
