Fix bogus lockdep warnings if multiple u64_stats_sync variables are
initialized in the same file.
With CONFIG_LOCKDEP, seqcount_init() is a macro which declares:
static struct lock_class_key __key;
Since u64_stats_init() is a function (albeit an inline one), all calls
within the same file end up using the same instance, effectively treating
them all as a single lock-class.
Fixes: 9464ca650008 ("net: make u64_stats_init() a function")

====================
ethtool HW timestamping statistics
The goal of this patch series is to introduce a common set of ethtool
statistics for hardware timestamping that a driver implementer can hook into.
The statistics counters added are based on what I believe are common
patterns/behaviors found across various hardware timestamping implementations
seen in the kernel tree today. The mlx5 family of devices is used
as the PoC for this patch series. Other vendors are more than welcome
to chime in on this series.

On startup, ovs-vswitchd probes different datapath features including
support for timeout policies. While probing, it tries to execute
certain operations with OVS_PACKET_ATTR_PROBE or OVS_FLOW_ATTR_PROBE
attributes set. These attributes tell the openvswitch module to not
log any errors when they occur as it is expected that some of the
probes will fail.
For some reason, setting the timeout policy ignores the PROBE attribute
and logs a failure anyway. This is causing the following kernel log
on each re-start of ovs-vswitchd:
kernel: Failed to associated timeout policy `ovs_test_tp'
Fix that by using the same logging macro that all other messages are
using. The message will still be printed at info level when needed
and will be rate limited, but with a net rate limiter instead of
generic printk one.
The nf_ct_set_timeout() itself will still print some info messages,
but at least this change makes logging in openvswitch module more
consistent.

Arnd Bergmann says:
====================
address all -Wunused-const warnings (the net part)
Compilers traditionally warn for unused 'static' variables, but not
if they are constant. The reason here is a custom for C++ programmers
to define named constants as 'static const' variables in header files
instead of using macros or enums.
In W=1 builds, we get warnings only static const variables in C
files, but not in headers, which is a good compromise, but this still
produces warning output in at least 30 files. These warnings are
almost all harmless, but also trivial to fix, and there is no
good reason to warn only about the non-const variables being unused.
I've gone through all the files that I found using randconfig and
allmodconfig builds and created patches to avoid these warnings,
with the goal of retaining a clean build once the option is enabled
by default.
Unfortunately, there is one fairly large patch ("drivers: remove
incorrect of_match_ptr/ACPI_PTR annotations") that touches
34 individual drivers that all need the same one-line change.
If necessary, I can split it up by driver or by subsystem,
but at least for reviewing I would keep it as one piece for
the moment.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
For 2 out of 3 of these changes we can simply swap in strscpy() as it
guarantess NUL-termination which is needed for the following trace
print.
trace_rpcgss_context() should use memcpy as its format specifier %.*s
allows for the length to be specifier (__entry->len). Due to this,
acceptor does not technically need to be NUL-terminated. Moreover,
swapping in strscpy() and keeping everything else the same could result
in truncation of the source string by one byte. To remedy this, we could
use `len + 1` but I am unsure of the size of the destination buffer so a
simple memcpy should suffice.
| TP_printk("win_size=%u expiry=%lu now=%lu timeout=%u acceptor=%.*s",
| __entry->window_size, __entry->expiry, __entry->now,
| __entry->timeout, __entry->len, __get_str(acceptor))
I suspect acceptor not to naturally be a NUL-terminated string due to
the presence of some stringify methods.

In the FireWire OHCI interrupt handler, if a bus reset interrupt has
occurred, mask bus reset interrupts until bus_reset_work has serviced and
cleared the interrupt.
Normally, we always leave bus reset interrupts masked. We infer the bus
reset from the self-ID interrupt that happens shortly thereafter. A
scenario where we unmask bus reset interrupts was introduced in 2008 in
a007bb857e0b26f5d8b73c2ff90782d9c0972620: If
OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we
will unmask bus reset interrupts so we can log them.
irq_handler logs the bus reset interrupt. However, we can't clear the bus
reset event flag in irq_handler, because we won't service the event until
later. irq_handler exits with the event flag still set. If the
corresponding interrupt is still unmasked, the first bus reset will
usually freeze the system due to irq_handler being called again each
time it exits. This freeze can be reproduced by loading firewire_ohci
with "modprobe firewire_ohci debug=-1" (to enable all debugging output).
Apparently there are also some cases where bus_reset_work will get called
soon enough to clear the event, and operation will continue normally.
This freeze was first reported a few months after a007bb85 was committed,
but until now it was never fixed. The debug level could safely be set
to -1 through sysfs after the module was loaded, but this would be
ineffectual in logging bus reset interrupts since they were only
unmasked during initialization.
irq_handler will now leave the event flag set but mask bus reset
interrupts, so irq_handler won't be called again and there will be no
freeze. If OHCI_PARAM_DEBUG_BUSRESETS is enabled, bus_reset_work will
unmask the interrupt after servicing the event, so future interrupts
will be caught as desired.
As a side effect to this change, OHCI_PARAM_DEBUG_BUSRESETS can now be
enabled through sysfs in addition to during initial module loading.
However, when enabled through sysfs, logging of bus reset interrupts will
be effective only starting with the second bus reset, after
bus_reset_work has executed.

The default highest_bank_bit of 15 didn't seem to cause issues so far
but downstream defines it to be 14. But similar to [0] leaving it on 14
(or 15 for that matter) causes some corruption issues with some
resolutions with DisplayPort, like 1920x1200.
So set it to 13 for now so that there's no screen corruption.

Commit 3ee34eabac2a ("lib/stackdepot: fix first entry having a 0-handle")
changed the meaning of the pool_index field to mean "the pool index plus
1". This made the code accessing this field less self-documenting, as
well as causing debuggers such as drgn to not be able to easily remain
compatible with both old and new kernels, because they typically do that
by testing for presence of the new field. Because stackdepot is a
debugging tool, we should make sure that it is debugger friendly.
Therefore, give the field a different name to improve readability as well
as enabling debugger backwards compatibility.
This is needed in 6.9, which would otherwise become an odd release with
the new semantics and old name so debuggers wouldn't recognize the new
semantics there.

PAT handling won't do the right thing in COW mappings: the first PTE (or,
in fact, all PTEs) can be replaced during write faults to point at anon
folios. Reliably recovering the correct PFN and cachemode using
follow_phys() from PTEs will not work in COW mappings.
Using follow_phys(), we might just get the address+protection of the anon
folio (which is very wrong), or fail on swap/nonswap entries, failing
follow_phys() and triggering a WARN_ON_ONCE() in untrack_pfn() and
track_pfn_copy(), not properly calling free_pfn_range().
In free_pfn_range(), we either wouldn't call memtype_free() or would call
it with the wrong range, possibly leaking memory.
To fix that, let's update follow_phys() to refuse returning anon folios,
and fallback to using the stored PFN inside vma->vm_pgoff for COW mappings
if we run into that.
We will now properly handle untrack_pfn() with COW mappings, where we
don't need the cachemode. We'll have to fail fork()->track_pfn_copy() if
the first page was replaced by an anon folio, though: we'd have to store
the cachemode in the VMA to make this work, likely growing the VMA size.
For now, lets keep it simple and let track_pfn_copy() just fail in that
case: it would have failed in the past with swap/nonswap entries already,
and it would have done the wrong thing with anon folios.
Simple reproducer to trigger the WARN_ON_ONCE() in untrack_pfn():
