arch/arm64/boot/dts/qcom/sdm850-lenovo-yoga-c630.dt.yaml: bridge@2c: reg:0:0: 45 was expected
According to the datasheet, the I2C address can be either 0x2c or 0x2d,
depending on the ADDR control input.

A packet received on a trunk will have bit 2 set in Forward DSA tagged
frame. Bit 1 can be either 0 or 1 and is otherwise undefined and bit 0
indicates the frame CFI. Masking with 7 thus results in frames as
being identified as being from a trunk when in fact they are not. Fix
the mask to just look at bit 2.

In commit b212921b13bd ("elf: don't use MAP_FIXED_NOREPLACE for elf
executable mappings") we still leave MAP_FIXED_NOREPLACE in place for
load_elf_interp.
Unfortunately, this will cause kernel to fail to start with:
1 (init): Uhuuh, elf segment at 00003ffff7ffd000 requested but the memory is mapped already
Failed to execute /init (error -17)
The reason is that the elf interpreter (ld.so) has overlapping segments.
readelf -l ld-2.31.so
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000

0x00000000000011ac 0x0000000000001328 RW 0x10000
The reason for this problem is the same as described in commit
ad55eac74f20 ("elf: enforce MAP_FIXED on overlaying elf segments").
Not only executable binaries, elf interpreters (e.g. ld.so) can have
overlapping elf segments, so we better drop MAP_FIXED_NOREPLACE and go
back to MAP_FIXED in load_elf_interp.

The objtool warning that the kvm instruction emulation code triggered
wasn't very useful:
arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception
in that it helpfully tells you which symbol name it had trouble figuring
out the relocation for, but it doesn't actually say what the unknown
symbol type was that triggered it all.
In this case it was because of missing type information (type 0, aka
STT_NOTYPE), but on the whole it really should just have printed that
out as part of the message.
Because if this warning triggers, that's very much the first thing you
want to know - why did reloc2sec_off() return failure for that symbol?
So rather than just saying you can't handle some type of symbol without
saying what the type _was_, just print out the type number too.

The recent change to make objtool aware of more symbol relocation types
(commit 24ff65257375: "objtool: Teach get_alt_entry() about more
relocation types") also added another check, and resulted in this
objtool warning when building kvm on x86:
arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception
The reason seems to be that kvm_fastop_exception() is marked as a global
symbol, which causes the relocation to ke kept around for objtool. And
at the same time, the kvm_fastop_exception definition (which is done as
an inline asm statement) doesn't actually set the type of the global,
which then makes objtool unhappy.
The minimal fix is to just not mark kvm_fastop_exception as being a
global symbol. It's only used in that one compilation unit anyway, so
it was always pointless. That's how all the other local exception table
labels are done.
I'm not entirely happy about the kinds of games that the kvm code plays
with doing its own exception handling, and the fact that it confused
objtool is most definitely a symptom of the code being a bit too subtle
and ad-hoc. But at least this trivial one-liner makes objtool no longer
upset about what is going on.

In cachefiles_mark_object_buried, the dentry in question may not have an
owner, and thus our cachefiles_object pointer may be NULL when calling
the tracepoint, in which case we will also not have a valid debug_id to

Check for NULL object in the tracepoint and if so, just set debug_id to
MAX_UINT as was done in 2908f5e101e3 ("fscache: Add a cookie debug ID

Netfilter fixes for net (v2)
The following patchset contains Netfilter fixes for net:
1) Move back the defrag users fields to the global netns_nf area.
Kernel fails to boot if conntrack is builtin and kernel is booted
with: nf_conntrack.enable_hooks=1. From Florian Westphal.
2) Rule event notification is missing relevant context such as
the position handle and the NLM_F_APPEND flag.
3) Rule replacement is expanded to add + delete using the existing
rule handle, reverse order of this operation so it makes sense
from rule notification standpoint.
4) Propagate to userspace the NLM_F_CREATE and NLM_F_EXCL flags
from the rule notification path.
Patches #2, #3 and #4 are used by 'nft monitor' and 'iptables-monitor'
userspace utilities which are not correctly representing the following
operations through netlink notifications:
- rule insertions
- rule addition/insertion from position handle
- create table/chain/set/map/flowtable/...

The bytes for max_power_out from the ibm-cffps devices differ in byte
order for some power supplies.
The Witherspoon power supply returns the bytes in MSB/LSB order.
The Rainier power supply returns the bytes in LSB/MSB order.
The Witherspoon power supply uses version cffps1. The Rainier power
supply should use version cffps2. If version is cffps1, swap the bytes
before output to max_power_out.
Tested:
Witherspoon before: 3148. Witherspoon after: 3148.
Rainier before: 53255. Rainier after: 2000.

The P10 (temp sensor version 0x10) doesn't do the same VRM status

drop the check for VRM fru type in the sysfs show function, and don't

This reverts commit 6decd1aad15f56b169217789630a0098b496de0e. CPULAUNCH
register is not set properly by some bootloaders, causing a regression
until a bootloader change is made, which is hard if not impossible on
some embedded devices. Revert the change until a more robust core
detection mechanism that works on MT7621S routers such as Netgear R6220
as well as platforms like Digi EX15 can be made.

Another round of removing redundant minItems/maxItems from new schema in
the recent merge window.
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

Commit 2d26f6e39afb ("net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings")
while getting rid of a runtime PM warning ended up breaking ethernet
on rk3399 based devices. By dropping an extra reference to the device,
the commit ends up enabling suspend / resume of the ethernet device -
which appears to be broken.
While the issue with runtime pm is being investigated, partially
revert commit 2d26f6e39afb to restore the network on rk3399.

When ocelot_flower.c calls ocelot_vcap_filter_add(), the filter has a
given filter->id.cookie. This filter is added to the block->rules list.
However, when ocelot_flower.c calls ocelot_vcap_block_find_filter_by_id()
which passes the cookie as argument, the filter is never found by
filter->id.cookie when searching through the block->rules list.
This is unsurprising, since the filter->id.cookie is an unsigned long,
but the cookie argument provided to ocelot_vcap_block_find_filter_by_id()
is a signed int, and the comparison fails.

syzbot reported another NULL deref in fifo_set_limit() [1]
I could repro the issue with :
unshare -n
tc qd add dev lo root handle 1:0 tbf limit 200000 burst 70000 rate 100Mbit
tc qd replace dev lo parent 1:0 pfifo_fast
tc qd change dev lo root handle 1:0 tbf limit 300000 burst 70000 rate 100Mbit
pfifo_fast does not have a change() operation.
Make fifo_set_limit() more robust about this.

Because Rui is now going to focus on work that is not related to the
maintenance of the thermal subsystem in the kernel, Rafael will start
to help Daniel with handling the development process as a new member
of the thermal maintainers team. Rui will continue to review patches
in that area.
The thermal development process flow will change so that the material
from the thermal git tree will be merged into the thermal branch of
the linux-pm.git tree before going into the mainline.
Update the information in MAINTAINERS accordingly.

We have never supported fasync properly, it would only fire when there
is something polling io_uring making it useless. The original support came
