firmware: cs_dsp: test_bin: Add tests for offsets > 0xffff
Add test cases for using the new long-offset block types to patch
memory that is >0xffff from the algorithm base.

This is just adding entries to the parameter data that have larger
offset values.

firmware: cs_dsp: test_bin: Run test cases on long-offset blocks
Run the patch block test cases using the new long-offset block type.

This adds a new set of parameterization that uses
cs_dsp_mock_bin_add_patch_off32() to create the patch blocks in the
test bin file.

The test cases for Halo Core with V3 file format include another
run of the tests with the new parameterization, so that the tests
are run on the standard blocks and the long-offset blocks.

This commit does not add any new cases for offsets > 0xffff.

firmware: cs_dsp: mock_bin: Add function to create long-offset patches
Add cs_dsp_mock_bin_add_patch_off32(). This is the same as
cs_dsp_mock_bin_add_patch() except that it puts the offset in the
new 32-bit offset field and modifies the block type to indicate
that it uses the long offset.

firmware: cs_dsp: mock_bin: Pass offset32 to cs_dsp_mock_bin_add_raw_block()
Add an argument to cs_dsp_mock_bin_add_raw_block() to pass a 32-bit
offset, and change the type of the existing offset argument to u16.

The cs_dsp_test_bin_error.c test uses cs_dsp_mock_bin_add_raw_block()
so it needs corresponding updates to pass 0 as the 32-bit offset.

Version 1 and 2 of the bin file format had a 16-bit offset on blocks
and the sample rate field of the blocks was not used. Version 3 adds
new block types that change the old sample rate field to be a 32-bit
offset with the old offset currently unused.

cs_dsp_mock_bin_add_raw_block() doesn't attempt to do any magic - its
purpose is to create a raw block exactly as specified by the calling
test code. So the test case can pass a value for both offset fields.

bc0305cb29
firmware: cs_dsp: Handle long-offset data blocks
Handle a new type of data block that has a 32-bit offset. These are
identical to the normal blocks except that the offset is now in the
32-bit field that was previously 'sr'.

A new file version of 3 indicates that it is mandatory to process
the long-offset blocks, so that older code without that support will
reject the file.

The original 'sr' field was never used by the driver so it has been
renamed offset32.

ASoC: rt1320: fix 32-bit link failure
A plain 64-bit division causes a link failure in some configurations:

ERROR: modpost: "__aeabi_uldivmod" [sound/soc/codecs/snd-soc-rt1320-sdw.ko] undefined!

Since this divides by a constant, using the div_u64() macro ends up
turning this into an efficient multiply/shift operation where possible.

In rt1320_calc_r0(), the open-coded shift seems a litle simpler.

ASoC: rockchip: Discard pm_runtime_put() return value
It is better to check directly whether or not CONFIG_PM has
been enabled instead of relying on an error value returned by
pm_runtime_put() in that case because pm_runtime_put() may also return
an error value in other cases, like after writing "on" to the devices'
runtime PM "control" attribute in sysfs for one example.

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

3766511de1 scripts: coccicheck: filter *.cocci files by MODE
Enhance the coccicheck script to filter *.cocci files based on the
specified MODE (e.g., report, patch). This ensures that only compatible
semantic patch files are executed, preventing errors such as:

    "virtual rule report not supported"

This error occurs when a .cocci file does not define a 'virtual <MODE>'
rule, yet is executed in that mode.

For example:

    make coccicheck M=drivers/hwtracing/coresight/ MODE=report

In this case, running "secs_to_jiffies.cocci" would trigger the error
because it lacks support for 'report' mode. With this change, such files
are skipped automatically, improving robustness and developer
experience.

91ff28ae6d x86/irqflags: Use ASM_OUTPUT_RM in native_save_fl()
clang is generating very inefficient code for native_save_fl() which is
used for local_irq_save() in critical spots.

Allowing the "pop %0" to use memory:

 1) forces the compiler to add annoying stack canaries when
    CONFIG_STACKPROTECTOR_STRONG=y in many places.

 2) Almost always is followed by an immediate "move memory,register"

One good example is _raw_spin_lock_irqsave, with 8 extra instructions

  ffffffff82067a30 <_raw_spin_lock_irqsave>:
  ffffffff82067a30:		...
  ffffffff82067a39:		53						push   %rbx

  // Three instructions to ajust the stack, read the per-cpu canary
  // and copy it to 8(%rsp)
  ffffffff82067a3a:		48 83 ec 10 			sub    $0x10,%rsp
  ffffffff82067a3e:		65 48 8b 05 da 15 45 02 mov    %gs:0x24515da(%rip),%rax 	   # <__stack_chk_guard>
  ffffffff82067a46:		48 89 44 24 08			mov    %rax,0x8(%rsp)

  ffffffff82067a4b:		9c						pushf

  // instead of pop %rbx, compiler uses 2 instructions.
  ffffffff82067a4c:		8f 04 24				pop    (%rsp)
  ffffffff82067a4f:		48 8b 1c 24 			mov    (%rsp),%rbx

  ffffffff82067a53:		fa						cli
  ffffffff82067a54:		b9 01 00 00 00			mov    $0x1,%ecx
  ffffffff82067a59:		31 c0					xor    %eax,%eax
  ffffffff82067a5b:		f0 0f b1 0f 			lock cmpxchg %ecx,(%rdi)
  ffffffff82067a5f:		75 1d					jne    ffffffff82067a7e <_raw_spin_lock_irqsave+0x4e>

  // three instructions to check the stack canary
  ffffffff82067a61:		65 48 8b 05 b7 15 45 02 mov    %gs:0x24515b7(%rip),%rax 	   # <__stack_chk_guard>
  ffffffff82067a69:		48 3b 44 24 08			cmp    0x8(%rsp),%rax
  ffffffff82067a6e:		75 17					jne    ffffffff82067a87

  ...

  // One extra instruction to adjust the stack.
  ffffffff82067a73:		48 83 c4 10 			add    $0x10,%rsp
  ...

  // One more instruction in case the stack was mangled.
  ffffffff82067a87:		e8 a4 35 ff ff			call   ffffffff8205b030 <__stack_chk_fail>

This patch changes nothing for gcc, but for clang saves ~20000 bytes of text
even though more functions are inlined.

4cc5373f2e clang: work around asm output constraint problems
Work around clang problems with "=rm" asm constraint.

clang seems to always chose the memory output, while it is almost
always the worst choice.

Add ASM_OUTPUT_RM so that we can replace "=rm" constraint
where it matters for clang, while not penalizing gcc.

18dfd1cbf6 Two left-over updates that could not go into -rc1 due to conflicts with
other series:
 
  - Simplify checks in arch_kfence_init_pool() since force_pte_mapping()
    already takes BBML2-noabort (break-before-make Level 2 with no aborts
    generated) into account
 
  - Remove unneeded SVE/SME fallback preserve/store handling in the arm64
    EFI. With the recent updates, the fallback path is only taken for EFI
    runtime calls from hardirq or NMI contexts. In practice, this only
    happens under panic/oops/emergency_restart() and no restoring of the
    user state expected. There's a corresponding lkdtm update to trigger
    a BUG() or panic() from hardirq context together with a fixup not to
    confuse clang/objtool about the control flow
 
 GCS (guarded control stacks) fix: flush the GCS locking state on exec,
 otherwise the new task will not be able to enable GCS (locked as
 disabled).

072c0b4f0f x86 fixes. Everyone else is already in holiday mood apparently.
- Add a missing "break" to fix param parsing in the rseq selftest.
 
 - Apply runtime updates to the _current_ CPUID when userspace is setting
   CPUID, e.g. as part of vCPU hotplug, to fix a false positive and to avoid
   dropping the pending update.
 
 - Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot, as it's not
   supported by KVM and leads to a use-after-free due to KVM failing to unbind
   the memslot from the previously-associated guest_memfd instance.
 
 - Harden against similar KVM_MEM_GUEST_MEMFD goofs, and prepare for supporting
   flags-only changes on KVM_MEM_GUEST_MEMFD memlslots, e.g. for dirty logging.
 
 - Set exit_code[63:32] to -1 (all 0xffs) when synthesizing a nested
   SVM_EXIT_ERR (a.k.a. VMEXIT_INVALID) #VMEXIT, as VMEXIT_INVALID is defined
   as -1ull (a 64-bit value).
 
 - Update SVI when activating APICv to fix a bug where a post-activation EOI
   for an in-service IRQ would effective be lost due to SVI being stale.
 
 - Immediately refresh APICv controls (if necessary) on a nested VM-Exit
   instead of deferring the update via KVM_REQ_APICV_UPDATE, as the request is
   effectively ignored because KVM thinks the vCPU already has the correct
   APICv settings.

Pull x86 kvm fixes from Paolo Bonzini:
 "x86 fixes.  Everyone else is already in holiday mood apparently.

   - Add a missing 'break' to fix param parsing in the rseq selftest

   - Apply runtime updates to the _current_ CPUID when userspace is
     setting CPUID, e.g. as part of vCPU hotplug, to fix a false
     positive and to avoid dropping the pending update

   - Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot, as
     it's not supported by KVM and leads to a use-after-free due to KVM
     failing to unbind the memslot from the previously-associated
     guest_memfd instance
