This test was added because of a bug in verifier.c:sync_linked_regs(),
upon range propagation it destroyed subreg_def marks for registers.
The test is written in a way to return an upper half of a register
that is affected by range propagation and must have it's subreg_def
preserved. This gives a return value of 0 and leads to undefined
return value if subreg_def mark is not preserved.

Range propagation must not affect subreg_def marks, otherwise the
following example is rewritten by verifier incorrectly when
BPF_F_TEST_RND_HI32 flag is set:

  0: call bpf_ktime_get_ns                   call bpf_ktime_get_ns
  1: r0 &= 0x7fffffff       after verifier   r0 &= 0x7fffffff
  2: w1 = w0                rewrites         w1 = w0
  3: if w0 < 10 goto +0     -------------->  r11 = 0x2f5674a6     (r)
  4: r1 >>= 32                               r11 <<= 32           (r)
  5: r0 = r1                                 r1 |= r11            (r)
  6: exit;                                   if w0 < 0xa goto pc+0
                                             r1 >>= 32
                                             r0 = r1
                                             exit

(or zero extension of w1 at (2) is missing for architectures that
 require zero extension for upper register half).

The following happens w/o this patch:
- r0 is marked as not a subreg at (0);
- w1 is marked as subreg at (2);
- w1 subreg_def is overridden at (3) by copy_register_state();
- w1 is read at (5) but mark_insn_zext() does not mark (2)
  for zero extension, because w1 subreg_def is not set;
- because of BPF_F_TEST_RND_HI32 flag verifier inserts random
  value for hi32 bits of (2) (marked (r));
- this random value is read at (5).

The function __bpf_ringbuf_reserve is invoked from a tracepoint, which
disables preemption. Using spinlock_t in this context can lead to a
"sleep in atomic" warning in the RT variant. This issue is illustrated

The TI_K3_M4_REMOTEPROC Kconfig entry selects OMAP2PLUS_MBOX, but that
driver in turn depends on other things, which the k4-m4 driver didn't.

This causes a Kconfig time warning:

  WARNING: unmet direct dependencies detected for OMAP2PLUS_MBOX
    Depends on [n]: MAILBOX [=y] && (ARCH_OMAP2PLUS || ARCH_K3)
    Selected by [m]:
    - TI_K3_M4_REMOTEPROC [=m] && REMOTEPROC [=y] && (ARCH_K3 || COMPILE_TEST [=y])

because you can't select something that is unavailable.

Make the dependencies for TI_K3_M4_REMOTEPROC match those of the
OMAP2PLUS_MBOX driver that it needs.

 "Collection of small cleanup and one fix:

   - Sort headers and struct forward declarations

   - Fix random selftest failures in some cases due to dirty tracking
     tests

   - Have the reserved IOVA regions mechanism work when a HWPT is used
     as a nesting parent. This updates the nesting parent's IOAS with
     the reserved regions of the device and will also install the ITS
     doorbell page on ARM.

 "Mostly just a set of fixes in here, or little changes that didn't get
  included in the initial pull request. This contains:

   - Move the SQPOLL napi polling outside the submission lock (Olivier)

   - Rename of the "copy buffers" API that got added in the 6.12 merge
     window. There's really no copying going on, it's just referencing
     the buffers. After a bit of consideration, decided that it was
     better to simply rename this to avoid potential confusion (me)

   - Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
     start + len tracking rather than having start / end in there, and
     by removing the caching of folio_mask when we can just calculate it
     from folio_shift when we need it (me)

   - Fixes for the SQPOLL affinity checking (me, Felix)

   - Fix for how cqring waiting checks for the presence of task_work.
     Just check it directly rather than check for a specific
     notification mechanism (me)

   - Tweak to how request linking is represented in tracing (me)

   - Fix a syzbot report that deliberately sets up a huge list of
     overflow entries, and then hits rcu stalls when flushing this list.
     Just check for the need to preempt, and drop/reacquire locks in the
     loop. There's no state maintained over the loop itself, and each
     entry is yanked from head-of-list (me)"

Pull clk updates from Stephen Boyd:
 "The core clk framework is left largely untouched this time around
  except for support for the newly ratified DT property
  'assigned-clock-rates-u64'.

  I'm much more excited about the support for loading DT overlays from
  KUnit tests so that we can test how the clk framework parses DT nodes
  during clk registration. The clk framework has some places that are
  highly DeviceTree dependent so this charts the path to extend the
  KUnit tests to cover even more framework code in the future. I've got
  some more tests on the list that use the DT overlay support, but they
  uncovered issues with clk unregistration that I'm still working on
  fixing.

  Outside the core, the clk driver update pile is dominated by Qualcomm
  and Renesas SoCs, making it fairly usual. Looking closer, there are
  fixes for things all over the place, like adding missing clk
  frequencies or moving defines for the number of clks out of DT binding
  headers into the drivers. There are even conversions of DT bindings to
  YAML and migration away from strings to describe clk topology. Overall
  it doesn't look unusual so I expect the new drivers to be where we'll
  have fixes in the coming weeks.

  Core:
   - KUnit tests for clk registration and fixed rate basic clk type
   - A couple more devm helpers, one consumer and one provider
   - Support for assigned-clock-rates-u64

  New Drivers:
   - Camera, display and GPU clocks on Qualcomm SM4450
   - Camera clocks on Qualcomm SM8150
   - Rockchip rk3576 clks
   - Microchip SAM9X7 clks
   - Renesas RZ/V2H(P) (R9A09G057) clks

   - Mark a bunch of struct freq_tbl const to reduce .data usage
   - Add Qualcomm MSM8226 A7PLL and Regera PLL support
   - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
     Trion, as they do differ
   - A number of fixes to the Qualcomm SM8550 display clock driver
   - Fold Qualcomm SM8650 display clock driver into SM8550 one
   - Add missing clocks and GDSCs needed for audio on Qualcomm MSM8998
   - Add missing USB MP resets, GPLL9, and QUPv3 DFS to Qualcomm SC8180X

Pull i2c updates from Wolfram Sang:
 "I2C core:

   - finally remove the I2C_COMPAT symbol after 15 years of deprecation

   - lock client addresses during initialization to prevent race
     conditions between different kinds of instantiation

   - use scoped foreach OF child loops

   - testunit cleanups and documentation improvements, as well as two
     new tests, one for repeated start and one for triggering SMBusAlert
     interrupts

  I2C host drivers:

   - DesignWare and Renesas I2C driver updates.

     The first has has undergone through a series of cleanups that have
     been sent to the mailing list a year ago for the first time and
     finally get merged in this pull request. They are many, from typos
     (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move inline
     functions to librarieas) and many others.

   - all the DesignWare Kconfig options have been grouped under the
     I2C_DESIGNWARE_CORE and this required some adaptation in many of
     the kernel configuration files for different arm and mips boards

  Cleanups:

   - improve the exit path in the runtime resume function for the
     Qualcomm Geni platform

   - get rid of the unused "target_addr" parameter in the Intel LJCA
     driver

   - intialize the restart_flag in the MediaTek controller in one single
     place

   - constify a few global data structures in the virtio driver

   - simplify the bus speed handling in the Renesas driver init function
     making it more readable

   - improved probe function of the Renesas R-Car driver

   - switch the iMX/MXC driver to use RUNTIME_PM_OPS() instead of
     SET_RUNTIME_PM_OPS()

   - iMX/MXC driver cleanups

   - use devm_clk_get_enabled() to simplify the Renesas EMEV2, Ingenic
     and MPC drivers

  Refactoring:

   - Fix a potential out of boundary array access in the Nuvoton driver.

     This is not a bug fix because the issue could never occur due to
     hardware not having the properties listed in the array. The change
     makes the driver more future proof and, at the same time, silences
     code analyzers.

  Improvements:

   - several patches improving the runtime power management handling of
     the Renesas I2C (riic) driver

   - use a more descriptive adapter name in the Intel i801 driver to
     show the presence of the IDF feature

   - kill pending transactions when irq's can't complete their handling
     in the Intel Denverton (ismt) driver, triggering a timeout

  New Feature:

   - support fast mode plus in the Renesas I2C (riic) driver

  New support:

   - Added support for:
      - Renesas R9A08G045
      - Rockchip RK3576
      - KEBA I2C
      - Theobroma Systems Mule Multiplexer.

   - new i2c-keba.c driver

   - new driver for The Mule i2c multiplexer

  Core I2C framework:

   - move runtime PM functions in order to allow them to be accessed
     during device add

  Devicetree:

   - nVidia and Qualcomm binding improvements

   - get rid of redundant "multi-master" property in the aspeed binding

   - convert i2c-sprd binding to YAML

  AT24 updates:

  - document a new model from giantec in DT bindings"
