If we are clearing an entry and for some reason it is not already

Introduce arm_smmu_make_s1_cd() to build the CD from the paging S1 domain,
and reorganize all the places programming S1 domain CD table entries to
call it.

Split arm_smmu_update_s1_domain_cd_entry() from
arm_smmu_update_ctx_desc_devices() so that the S1 path has its own call
chain separate from the unrelated SVA path.

arm_smmu_update_s1_domain_cd_entry() only works on S1 domains attached to
RIDs and refreshes all their CDs. Remove case (3) from
arm_smmu_write_ctx_desc() as it is now handled by directly calling
arm_smmu_write_cd_entry().

Remove the forced clear of the CD during S1 domain attach,
arm_smmu_write_cd_entry() will do this automatically if necessary.

[will: Drop unused arm_smmu_clean_cd_entry() function]
Signed-off-by: Will Deacon <will@kernel.org>

CD table entries and STE's have the same essential programming sequence,
just with different types. Use the new ops indirection to link CD
programming to the common writer.

In a few more patches all CD writers will call an appropriate make
function and then directly call arm_smmu_write_cd_entry().
arm_smmu_write_ctx_desc() will be removed.

Until then lightly tweak arm_smmu_write_ctx_desc() to also use the new
programmer by using the same logic as right now to build the target CD on
the stack, sanitizing it to meet the used rules, and then using the
writer.

Sanitizing is necessary because the writer expects that the currently
programmed CD follows the used rules. Next patches add new make functions
and new direct calls to arm_smmu_write_cd_entry() which will require this.

The Qualcomm TBU debug support introduced by 414ecb03
("iommu/arm-smmu-qcom-debug: Add support for TBUs") provides its own
driver initialisation function, which breaks the link when the core SMMU
driver is built as a module:

  ld.lld: error: duplicate symbol: init_module
  >>> defined at arm-smmu.c
  >>>            drivers/iommu/arm/arm-smmu/arm-smmu.o:(init_module)
  >>> defined at arm-smmu-qcom-debug.c
  >>>            drivers/iommu/arm/arm-smmu/arm-smmu-qcom-debug.o:(.init.text+0x4)

Since we're late in the cycle, just make the debug features depend on a
non-modular SMMU driver for now while the initialisation is reworked to
hang off qcom_smmu_impl_init().

Threaded IRQ handlers run in a less critical context compared to normal
IRQs, so they can perform more complex and time-consuming operations
without causing significant delays in other parts of the kernel.
During a context fault, it might be needed to do more processing and
gather debug information from TBUs in the handler. These operations may
sleep, so add an option to use a threaded IRQ handler in these cases.

Operating the TBUs (Translation Buffer Units) from Linux on Qualcomm
platforms can help with debugging context faults. To help with that,
the TBUs can run ATOS (Address Translation Operations) to manually
trigger address translation of IOVA to physical address in hardware
and provide more details when a context fault happens.

The driver will control the resources needed by the TBU to allow
running the debug operations such as ATOS, check for outstanding
transactions, do snapshot capture etc.

Now that the BLOCKED and IDENTITY behaviors are managed with their own
domains change to the domain_alloc_paging() op.

The check for using_legacy_binding is now redundant,
arm_smmu_def_domain_type() always returns IOMMU_DOMAIN_IDENTITY for this
mode, so the core code will never attempt to create a DMA domain in the
first place.

Since commit a4fdd976 ("iommu: Use flush queue capability") the core
code only passes in IDENTITY/BLOCKED/UNMANAGED/DMA domain types. It will
not pass in IDENTITY or BLOCKED if the global statics exist, so the test
for DMA is also redundant now too.

The disable_bypass parameter has been mostly meaningless for a long time
since the introduction of default domains. Its original intent is now
fulfilled by the controls users have over the default domain type, and
its remaining effect in the brief window between Stream Table
initialisation and default domain creation hardly seems worth the
complication. Furthermore, thanks to 2-level Stream Tables, disabling
disable_bypass (there's another reason not to like it right there) has
never guaranteed that any particular StreamID *will* bypass anyway - any
device which might actually care about that wants RMRs - so there's not
really much lost by taking away that option (which has already been
non-default for nearing 6 years now).

As part of this, also remove the weird behaviour where we "successfully"
probe and register a non-functional SMMU if the DT "#iommu-cells"
property is wrong. I have no memory of what possessed me to think that
was a good idea at the time, and by now I suspect it's likely to break
things worse than simply failing probe would.

When KCSAN and CONSTRUCTORS are enabled, one can trigger the

Usually, when objtool runs on the .o objects, it does generate a section
.return_sites which contains all offsets in the objects to the return
thunks of the functions present there. Those return thunks then get
patched at runtime by the alternatives.

KCSAN and CONSTRUCTORS add this to the object file's .text.startup

Objtool has run already so that second constructor's return thunk cannot
be added to the .return_sites section and thus the return thunk remains
unpatched and the warning rightfully fires.

do not contain data races one would be interested about.

The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.

Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.

There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.

Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

Pull SCSI fixes and updates from James Bottomley:
 "Fully half this pull is updates to lpfc and qla2xxx which got
  committed just as the merge window opened. A sizeable fraction of the
  driver updates are simple bug fixes (and lock reworks for bug fixes in
  the case of lpfc), so rather than splitting the few actual
  enhancements out, we're just adding the drivers to the -rc1 pull.

  The enhancements for lpfc are log message removals, copyright updates
  and three patches redefining types. For qla2xxx it's just removing a
  debug message on module removal and the manufacturer detail update.

  The two major fixes are the sg teardown race and a core error leg
  problem with the procfs directory not being removed if we destroy a
  created host that never got to the running state. The rest are minor
  fixes and constifications"

One fix in the i801 driver where a bug caused touchpad
malfunctions on some Lenovo P1 models by incorrectly overwriting
a status variable during successful SMBUS transactions.

Commit c33621b4 ("x86/virt/tdx: Wire up basic SEAMCALL functions")
introduced a new instance of core-y instead of the standardized obj-y
syntax.

X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently;
into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into
arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild.

This is problematic when you build a single object in parallel because
multiple threads attempt to build the same file.

  $ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o
    [ snip ]
    AS      arch/x86/virt/vmx/tdx/seamcall.o
    AS      arch/x86/virt/vmx/tdx/seamcall.o
  fixdep: error opening file: arch/x86/virt/vmx/tdx/.seamcall.o.d: No such file or directory
  make[4]: *** [scripts/Makefile.build:362: arch/x86/virt/vmx/tdx/seamcall.o] Error 2

Use the obj-y syntax, as it works correctly.
