The HAVE_CFI_ICALL_NORMALIZE_INTEGERS option has some tricky conditions
when KASAN or GCOV are turned on, as in that case we need some clang and
rustc fixes [1][2] to avoid boot failures. The intent with the current
setup is that you should be able to override the check and turn on the
option if your clang/rustc has the fix. However, this override does not
work in practice. Thus, use the new RUSTC_LLVM_VERSION to correctly
implement the check for whether the fix is available.
Additionally, remove KASAN_HW_TAGS from the list of incompatible
options. The CFI_ICALL_NORMALIZE_INTEGERS option is incompatible with
KASAN because LLVM will emit some constructors when using KASAN that are
assigned incorrect CFI tags. These constructors are emitted due to use
of -fsanitize=kernel-address or -fsanitize=kernel-hwaddress that are
respectively passed when KASAN_GENERIC or KASAN_SW_TAGS are enabled.
However, the KASAN_HW_TAGS option relies on hardware support for MTE
instead and does not pass either flag. (Note also that KASAN_HW_TAGS
does not `select CONSTRUCTORS`.)

This device is a subset of J784S4 and shares the same memory map and
thus the nodes are being reused from J784S4 to avoid duplication.
Here are some of the salient features of the J742S2 automotive grade
application processor:
The J742S2 SoC belongs to the K3 Multicore SoC architecture platform,
providing advanced system integration in automotive, ADAS and industrial
applications requiring AI at the network edge. This SoC extends the K3
Jacinto 7 family of SoCs with focus on raising performance and
integration while providing interfaces, memory architecture and compute
performance for multi-sensor, high concurrency applications.
Some changes that this devices has from J784S4 are:
* 4x Cortex-A72 vs 8x Cortex-A72
* 3x C7x DSP vs 4x C7x DSP
* 4 port ethernet switch vs 8 port ethernet switch
( Refer Table 2-1 for Device comparison with J7AHP )

Commit
f69759be251d ("x86/CPU/AMD: Move Zenbleed check to the Zen2 init function")
causes a bit in the DE_CFG MSR to get set erroneously after a microcode late
load.
The microcode late load path calls into amd_check_microcode() and subsequently
zen2_zenbleed_check(). Since the above commit removes the cpu_has_amd_erratum()
call from zen2_zenbleed_check(), this will cause all non-Zen2 CPUs to go
through the function and set the bit in the DE_CFG MSR.
Call into the Zenbleed fix path on Zen2 CPUs only.

As there is very little ordering in the KVM API, userspace can
instanciate a half-baked GIC (missing its memory map, for example)
at almost any time.
This means that, with the right timing, a thread running vcpu-0
can enter the kernel without a GIC configured and get a GIC created
behind its back by another thread. Amusingly, it will pick up
that GIC and start messing with the data structures without the
GIC having been fully initialised.
Similarly, a thread running vcpu-1 can enter the kernel, and try
to init the GIC that was previously created. Since this GIC isn't
properly configured (no memory map), it fails to correctly initialise.
And that's the point where we decide to teardown the GIC, freeing all
its resources. Behind vcpu-0's back. Things stop pretty abruptly,
with a variety of symptoms. Clearly, this isn't good, we should be
a bit more careful about this.
It is obvious that this guest is not viable, as it is missing some
important part of its configuration. So instead of trying to tear
bits of it down, let's just mark it as *dead*. It means that any
further interaction from userspace will result in -EIO. The memory
will be released on the "normal" path, when userspace gives up.

Konstantin reports the maintainer's address bounces.
There is no other maintainer and the driver is quite old.
There is a good chance nobody is using this driver any more.
Let's try to remove it completely, we can revert it back in

Commit ac9f97ff8b32 ("powerpc/8xx: Inconditionally use task PGDIR in
DTLB misses") relies on re-reading DAR register to know if an error is
due to a missing copy of a PMD entry in task's PGDIR, allthough DAR
was already read in the exception prolog and copied into thread
struct. This is because is it done very early in the exception and
there are not enough registers available to keep a pointer to thread
struct.
However, dcbz instruction is buggy and doesn't update DAR register on
fault. That is detected and generates a call to FixupDAR workaround
which updates DAR copy in thread struct but doesn't fix DAR register.
Let's fix DAR in addition to the update of DAR copy in thread struct.

function parameters, return value and stack. Since it is a subset of
pt_regs, it should only be used by its accessor functions. But because
pt_regs can easily be taken from ftrace_regs (on most archs), it is
tempting to use it directly. But when running on other architectures, it
may fail to build or worse, build but crash the kernel!
Instead, make struct ftrace_regs an empty structure and have the
architectures define __arch_ftrace_regs and all the accessor functions
will typecast to it to get to the actual fields. This will help avoid
usage of ftrace_regs directly.

num-slots was not part of the dw-mmc binding and the last slipage of
one of them seeping in from the vendor kernel was removed way back in
2017. Somehow the nanopi-r2s-plus managed to smuggle another on in the
kernel, so remove that as well.

There are two LEDs on the board, power and user events.
Currently both are assigned undocumented IR(-remote)
triggers that are probably only part of the vendor-kernel.
To make dtbs check happier, assign the power-led to a generic
default-on trigger and the user led to the documented rc-feedback
trigger that should mostly match its current usage.

All Theobroma boards use a ti,amc6821 as fan controller.
It normally runs in an automatically controlled way and while it may be
possible to use it as part of a dt-based thermal management, this is
not yet specified in the binding, nor implemented in any kernel.
Newer boards already don't contain that #cooling-cells property, but
older ones do. So remove them for now, they can be re-added if thermal
integration gets implemented in the future.
There are two further occurences in v6.12-rc in px30-ringneck and
rk3399-puma, but those already get removed by the i2c-mux conversion
scheduled for 6.13 . As the undocumented property is in the kernel so
long, I opted for not causing extra merge conflicts between 6.12 and 6.13

Ensure that VFs used in isolation, that is with their parent PF not
visible to the configuration but with their RID exposed, are treated
compatibly with existing isolated VF use cases without exposed RID
including RoCE Express VFs. This allows creating configurations where
one LPAR manages PFs while their child VFs are used by other LPARs. This
gives the LPAR managing the PFs a role analogous to that of the
hypervisor in a typical use case of passing child VFs to guests.
Instead of creating a multifunction struct zpci_bus whenever a PCI
function with RID exposed is discovered only create such a bus for
configured physical functions and only consider multifunction busses
when searching for an existing bus. Additionally only set zdev->devfn to
the devfn part of the RID once the function is added to a multifunction
bus.
This also fixes probing of more than 7 such isolated VFs from the same
physical bus. This is because common PCI code in pci_scan_slot() only
looks for more functions when pdev->multifunction is set which somewhat
counter intutively is not the case for VFs.
Note that PFs are looked at before their child VFs is guaranteed because
we sort the zpci_list by RID ascending.

The newly introduced topology ID (TID) field in the CLP Query PCI
Function explicitly identifies groups of PCI functions whose RIDs belong
to the same (sub-)topology. When available use the TID instead of the
PCHID to match zPCI busses/domains for multi-function devices. Note that
currently only a single PCI bus per TID is supported. This change is
required because in future machines the PCHID will not identify a PCI
card but a specific port in the case of some multi-port NICs while from
a PCI point of view the entire card is a subtopology.

Instead of relying on the observed but not architected firmware behavior
that PCI functions from the same card are listed in ascending RID order
in clp_list_pci() ensure this by sorting. To allow for sorting separate
the initial clp_list_pci() and creation of the virtual PCI busses.
Note that fundamentally in our per-PCI function hotplug design non RID
order of discovery is still possible. For example when the two PFs of
a two port NIC are hotplugged after initial boot and in descending RID
order. In this case the virtual PCI bus would be created by the second
PF using that PF's UID as domain number instead of that of the first PF.
Thus the domain number would then change from the UID of the second PF
to that of the first PF on reboot but there is really nothing we can do
about that since changing domain numbers at runtime seems even worse.
This only impacts the domain number as the RIDs are consistent and thus
even with just the second PF visible it will show up in the correct
position on the virtual bus.

The parameters for the diag 0x258 are real addresses, not virtual, but

Previously, access_guest_page() did not check whether the given guest
address is inside of a memslot. This is not a problem, since
kvm_write_guest_page/kvm_read_guest_page return -EFAULT in this case.
However, -EFAULT is also returned when copy_to/from_user fails.
When emulating a guest instruction, the address being outside a memslot
usually means that an addressing exception should be injected into the
guest.
Failure in copy_to/from_user however indicates that something is wrong
in userspace and hence should be handled there.
To be able to distinguish these two cases, return PGM_ADDRESSING in
access_guest_page() when the guest address is outside guest memory. In
access_guest_real(), populate vcpu->arch.pgm.code such that
kvm_s390_inject_prog_cond() can be used in the caller for injecting into
the guest (if applicable).
Since this adds a new return value to access_guest_page(), we need to make
sure that other callers are not confused by the new positive return value.
There are the following users of access_guest_page():
- access_guest_with_key() does the checking itself (in
guest_range_to_gpas()), so this case should never happen. Even if, the
handling is set up properly.
- access_guest_real() just passes the return code to its callers, which
are:
- read_guest_real() - see below
- write_guest_real() - see below
There are the following users of read_guest_real():
- ar_translation() in gaccess.c which already returns PGM_*
- setup_apcb10(), setup_apcb00(), setup_apcb11() in vsie.c which always
return -EFAULT on read_guest_read() nonzero return - no change
- shadow_crycb(), handle_stfle() always present this as validity, this
could be handled better but doesn't change current behaviour - no change
There are the following users of write_guest_real():
- kvm_s390_store_status_unloaded() always returns -EFAULT on
write_guest_real() failure.
