62bb2054f9 eeprom: at25: expose JEDEC ID via sysfs
Return the raw JEDEC ID bytes as returned by the RDID command, even for
variations that have the bytes in reverse order. This way we can avoid
ambiguity if the manufacturer ever releases a new chip that returns them
according to standard.

3fcd9a0fbb eeprom: at25: add support for Infineon Cypress QSN FRAMs
Add support for Infineon Cypress CY15****QSN FRAM chips.
Unlike the QN variants these chips have an 8 byte JEDEC ID.

The layout of the serial number matches that of already supported chips
like the CY15B204QN, so make the read-out unconditional.

Tested with the CY15B204QSN. According to Infineon datasheets, all QSN
variants appear to share a consistent pattern so the size should be
correctly detected based on the density bits in the ID:

CY15B201QSN: 0x00 00 00 00 06 82 54 40, density_id:  8: 1Mb
CY15B102QSN: 0x00 00 00 00 06 82 51 48, density_id:  9: 2Mb
CY15B204QSN: 0x00 00 00 00 06 82 54 50, density_id: 10: 4Mb
CY15V108QSN: 0x00 00 00 00 06 82 52 58, density_id: 11: 8Mb

The documentation had a TODO questioning whether the unit was in

0bb23328ab pps: generators: remove broken pps_gen_parport driver
This driver was introduced in January 2011 and has been marked
BROKEN for almost its entire existence, since commit 95b90afec3
("pps: make pps_gen_parport depend on BROKEN") in March 2011.
It is unlikely anyone will fix the driver at this point.

bc2e4bc952 mcb: fix incorrect sanity check
__mcb_register_driver() makes some sanity checks over mcb_driver
to check if .probe and .remove callbacks are set.  However, since commit
3bd13ae04c ("gpio: menz127: simplify error path and remove remove()")
removed the .remove callback from menz127-gpio.c, not all mcb device
drivers implement .remove callback.

Remove .remove check to ensure all mcb device drivers can be loaded.

b7f42b0cfb rust_binder: refactor context management to use KVVec
Replace the linked list management in context.rs with KVVec.
This simplifies the ownership model by using standard
Arc-based tracking and moves away from manual unsafe list removals.

The refactor improves memory safety by leveraging Rust's contiguous
collection types while maintaining proper error propagation for
allocation failures during process registration.

6342969daf keys/trusted_keys: fix handle passed to tpm_buf_append_name during unseal
TPM2_Unseal[1] expects the handle of a loaded data object, and not the
handle of the parent key. But the tpm2_unseal_cmd provides the parent
keyhandle instead of blob_handle for the session HMAC calculation. This
causes unseal to fail.

Fix this by passing blob_handle to tpm_buf_append_name().

The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after
a cold boot.

A quirk already exists for "ZenBook UX425", but some Zenbooks report
"Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive,
the existing quirk is not applied to these "extra special" Zenbooks.

Testing confirms that this model needs the same quirks as the ZenBook
UX425 variants.

Pull RISC-V fixes from Paul Walmsley:
 "The notable changes here are the three RISC-V timer compare register
  update sequence patches. These only apply to RV32 systems and are
  related to the 64-bit timer compare value being split across two
  separate 32-bit registers.

  We weren't using the appropriate three-write sequence, documented in
  the RISC-V ISA specifications, to avoid spurious timer interrupts
  during the update sequence; so, these patches now use the recommended
  sequence.

  This doesn't affect 64-bit RISC-V systems, since the timer compare
  value fits inside a single register and can be updated with a single
  write.

   - Fix the RISC-V timer compare register update sequence on RV32
     systems to use the recommended sequence in the RISC-V ISA manual

     This avoids spurious interrupts during updates

   - Add a dependence on the new CONFIG_CACHEMAINT_FOR_DMA Kconfig
     symbol for Renesas and StarFive RISC-V SoCs

   event that can display fields from both events as well as the time
   delta that took place between the events. It can also pass a
   stacktrace from the first event so that it can be displayed by the
   synthetic event (this is useful to get a stacktrace of a task
   scheduling out when blocked and recording the time it was blocked
   for).

   A synthetic event can also connect an existing synthetic event to
   another event. An issue was found that if the first synthetic event
   had a stacktrace as one of its fields, and that stacktrace field was
   passed to the new synthetic event to be displayed, it would crash the
   kernel. This was due to the stacktrace not being saved as a
   stacktrace but was still marked as one. When the stacktrace was read,
   it would try to read an array but instead read the integer metadata
   of the stacktrace and dereferenced a bad value.

   Fix this by saving the stacktrace field as a stacktrace.

 - Fix possible overflow in cmp_mod_entry() compare function

   A binary search is used to find a module address and if the addresses
   are greater than 2GB apart it could lead to truncation and cause a
   bad search result. Use normal compares instead of a subtraction
   between addresses to calculate the compare value.

 - Fix output of entry arguments in function graph tracer

   Depending on the configurations enabled, the entry can be two
   different types that hold the argument array. The macro
   FGRAPH_ENTRY_ARGS() is used to find the correct arguments from the
   given type. One location was missed and still referenced the
   arguments directly via entry->args and could produce the wrong value
   depending on how the kernel was configured.

 - Fix memory leak in scripts/tracepoint-update build tool

   If the array fails to allocate, the memory for the values needs to be
   freed and was not. Free the allocated values if the array failed to
   allocate.
