ffcfd071ee spi: cs42l43: Property entry should be a null-terminated array
The software node does not specify a count of property entries, so the
array must be null-terminated.

When unterminated, this can lead to a fault in the downstream cs35l56
amplifier driver, because the node parse walks off the end of the
array into unknown memory.

87aa3c8d8c spi: intel: Allow writeable MTD partition with module param
The MTD device is blocked from writing to the SPI-NOR chip if any region
of it is write-protected, even if "writeable=1" module parameter is set.

Add ability to bypass this behaviour by introducing new module parameter
"ignore_protestion_status" which allows to rely on the write protection
mechanism of SPI-NOR chip itself, which most modern chips (since
the 1990'+) have already implemented.

Any erase/write operations performed on the write-protected section will
be rejected by the chip.

8b61c8919d spi: Add driver for the RZ/V2H(P) RSPI IP
The Renesas RZ/V2H(P) RSPI IP supports 4-wire and 3-wire
serial communications in both host role and target role.
It can use a DMA, but the I/O can also be driven by the
processor.

RX-only, TX-only, and RX-TX operations are available in
DMA mode, while in processor I/O mode it only RX-TX
operations are supported.

Add a driver to support 4-wire serial communications as
host role in processor I/O mode.

Introduced support for the new SPI IP (SPISG) driver. The SPISG is
a communication-oriented SPI controller from Amlogic,supporting
three operation modes: PIO, block DMA, and scatter-gather DMA.

Due to there is no FIFO, PIO mode can only transfer one word at
a time, which is extremely slow. Therefore, this mode was not
implemented.

SG2044 and SG2042 have similar SPI-NOR flash controller design,
but have incompatibility which causes existing driver
not working on SG2042:
1. SPI-NOR flash controller on SG2042 have no OPT register.
2. FIFO trigger level on SG2042 should be strictly less than 8.

So introduce a new configurable chip_info structure to hold the
different configuration.

With further testing, directly using the spi-sg2044-nor driver on SG2042
does not work. SG2042 is found to lack full compatibility with SG2044.
SG2044 has OPT register and it's necessary to write but SG2042 does not.
Due to other possible hardware detail differences, it is better
to bind SG2042 independently.

1f590fa4b9 spi: spi-qpic-snand: simplify bad block marker duplication
Due to the expectations of the SPINAND code, the driver duplicates
the bad block markers during raw OOB reads.

It has been implemented by using two if statements, and due to the
opposite conditions one of conditional codepaths always runs. Since
the effect of both codepaths is the same, remove the if statements
and use a single line solution instead.

Also add a note about why the duplication is required.

No functional changes intended.

2013e8c2e6 Merge tag 'trace-v6.16-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:

 - Fix timerlat with use of FORTIFY_SOURCE

   FORTIFY_SOURCE was added to the stack tracer where it compares the
   entry->caller array to having entry->size elements.

   timerlat has the following:

      memcpy(&entry->caller, fstack->calls, size);
      entry->size = size;

   Which triggers FORTIFY_SOURCE as the caller is populated before the
   entry->size is initialized.

   Swap the order to satisfy FORTIFY_SOURCE logic.

 - Add down_write(trace_event_sem) when adding trace events in modules

   Trace events being added to the ftrace_events array are protected by
   the trace_event_sem semaphore. But when loading modules that have
   trace events, the addition of the events are not protected by the
   semaphore and loading two modules that have events at the same time
   can corrupt the list.

   Also add a lockdep_assert_held(trace_event_sem) to
   _trace_add_event_dirs() to confirm it is held when iterating the
   list.

The controller should have been set as XTYPE_XBOX360 and not XTYPE_XBOX.
Also the entry is in the wrong place. Fix it.

b5e8acc14d tracing: Add down_write(trace_event_sem) when adding trace event
When a module is loaded, it adds trace events defined by the module. It
may also need to modify the modules trace printk formats to replace enum
names with their values.

If two modules are loaded at the same time, the adding of the event to the
ftrace_events list can corrupt the walking of the list in the code that is
modifying the printk format strings and crash the kernel.

The addition of the event should take the trace_event_sem for write while
it adds the new event.

Also add a lockdep_assert_held() on that semaphore in
__trace_add_event_dirs() as it iterates the list.

85a3bce695 tracing/osnoise: Fix crash in timerlat_dump_stack()

__timerlat_dump_stack() constructs the ftrace stack entry like this:

struct stack_entry *entry;
...
memcpy(&entry->caller, fstack->calls, size);
entry->size = fstack->nr_entries;

Since commit e7186af7fb ("tracing: Add back FORTIFY_SOURCE logic to
kernel_stack event structure"), struct stack_entry marks its caller
field with __counted_by(size). At the time of the memcpy, entry->size
contains garbage from the ringbuffer, which under some circumstances is
zero, triggering a kernel panic by buffer overflow.

Populate the size field before the memcpy so that the out-of-bounds
check knows the correct size. This is analogous to
__ftrace_trace_stack().
