Pull ARM SoC fixes from Arnd Bergmann:
"These are the latest bug fixes that have come up in the soc tree. Most
of these are fairly minor. Most notably, the majority of changes this
time are not for dts files as usual.
- Updates to the addresses of the broadcom and aspeed entries in the
MAINTAINERS file.
- Defconfig updates to address a regression on samsung and a build
warning from an unknown Kconfig symbol
- Build fixes for the StrongARM and Uniphier platforms
- Code fixes for SCMI and FF-A firmware drivers, both of which had a
simple bug that resulted in invalid data, and a lesser fix for the
optee firmware driver
- Multiple fixes for the recently added loongson/loongarch "guts" soc
driver
- Devicetree fixes for RISC-V on the startfive platform, addressing
issues with NOR flash, usb and uart.
- Multiple fixes for NXP i.MX8/i.MX9 dts files, fixing problems with
clock, gpio, hdmi settings and the Makefile
- Bug fixes for i.MX firmware code and the OCOTP soc driver
- Multiple fixes for the TI sysc bus driver
- Minor dts updates for TI omap dts files, to address boot time
warnings and errors"

The locomolcd driver has one remaining missing-prototype warning:
drivers/video/backlight/locomolcd.c:83:6: error: no previous prototype for 'locomolcd_power' [-Werror=missing-prototypes]
There is in fact an unused prototype with a similar name in a global
header, so move the actual one there and remove the old one.

Fixes for omaps and ti-sysc
Fixes for several ti-sysc interconnect target module driver issues for
external abort on non-linefetch, am35x soc match, and uart module quirks
handling needed for devices to work and to allow device wake-up to work.
Fixes for droid4 boot time errors and warnings as noticed after boot doing
dmesg -lerr,warn. Let's also cut down the debug uart noise by using
overrun-throttle-ms, and downgrade the u-boot version warnings to
debug statements to further reduce the boot time noise with warnings.

We should be able to see real issues with dmesg -l err,warn. The u-boot
revision warning should be a debug statement rather than a warning.

On mapphone devices we may get lots of noise on the micro-USB port in debug
uart mode until the phy-cpcap-usb driver probes. Let's limit the noise by
using overrun-throttle-ms.
Note that there is also a related separate issue where the charger cable
connected may cause random sysrq requests until phy-cpcap-usb probes that
still remains.

Commit 0840242e8875 ("ARM: dts: Configure clock parent for pwm vibra")
attempted to fix the PWM settings but ended up causin an additional clock
reparenting error:
clk: failed to reparent abe-clkctrl:0060:24 to sys_clkin_ck: -22
Only timer9 is in the PER domain and can use the sys_clkin_ck clock source.
For timer8, the there is no sys_clkin_ck available as it's in the ABE
domain, instead it should use syc_clk_div_ck. However, for power
management, we want to use the always on sys_32k_ck instead.

Fix "thermal_sys: cpu_thermal: Failed to read thermal-sensors cells: -2"
error on boot for omap3/4. This is caused by wrong addressing in the dts
for bandgap sensor for single sensor instances.
Note that omap4-cpu-thermal.dtsi is shared across omap4/5 and dra7, so
we can't just change the addressing in omap4-cpu-thermal.dtsi.

There are several functions involved for performing the functionality
of evtchn_do_upcall():
- __xen_evtchn_do_upcall() doing the real work
- xen_hvm_evtchn_do_upcall() just being a wrapper for
__xen_evtchn_do_upcall(), exposed for external callers
- xen_evtchn_do_upcall() calling __xen_evtchn_do_upcall(), too, but
without any user
Simplify this maze by:
- removing the unused xen_evtchn_do_upcall()
- removing xen_hvm_evtchn_do_upcall() as the only left caller of
__xen_evtchn_do_upcall(), while renaming __xen_evtchn_do_upcall() to
xen_evtchn_do_upcall()

Pull kvm updates from Paolo Bonzini:
"ARM:
- Clean up vCPU targets, always returning generic v8 as the preferred
target
- Trap forwarding infrastructure for nested virtualization (used for
traps that are taken from an L2 guest and are needed by the L1
hypervisor)
- FEAT_TLBIRANGE support to only invalidate specific ranges of
addresses when collapsing a table PTE to a block PTE. This avoids
that the guest refills the TLBs again for addresses that aren't
covered by the table PTE.
- Fix vPMU issues related to handling of PMUver.
- Don't unnecessary align non-stack allocations in the EL2 VA space
- Drop HCR_VIRT_EXCP_MASK, which was never used...
- Don't use smp_processor_id() in kvm_arch_vcpu_load(), but the cpu
parameter instead
- Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
- Remove prototypes without implementations
RISC-V:
- Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
- Added ONE_REG interface for SATP mode
- Added ONE_REG interface to enable/disable multiple ISA extensions
- Improved error codes returned by ONE_REG interfaces
- Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
- Added get-reg-list selftest for KVM RISC-V
s390:
- PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
- Guest debug fixes (Ilya)
x86:
- Clean up KVM's handling of Intel architectural events
- Intel bugfixes
- Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use
debug registers and generate/handle #DBs
- Clean up LBR virtualization code
- Fix a bug where KVM fails to set the target pCPU during an IRTE
update
- Fix fatal bugs in SEV-ES intrahost migration
- Fix a bug where the recent (architecturally correct) change to
reinject #BP and skip INT3 broke SEV guests (can't decode INT3 to
skip it)
- Retry APIC map recalculation if a vCPU is added/enabled
- Overhaul emergency reboot code to bring SVM up to par with VMX, tie
the "emergency disabling" behavior to KVM actually being loaded,
and move all of the logic within KVM
- Fix user triggerable WARNs in SVM where KVM incorrectly assumes the
TSC ratio MSR cannot diverge from the default when TSC scaling is
disabled up related code
- Add a framework to allow "caching" feature flags so that KVM can
check if the guest can use a feature without needing to search
guest CPUID
- Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
- Fix KVM's handling of !visible guest roots to avoid premature
triple fault injection
- Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the
API surface that is needed by external users (currently only
KVMGT), and fix a variety of issues in the process
Generic:
- Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier
events to pass action specific data without needing to constantly
update the main handlers.
- Drop unused function declarations
Selftests:
- Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
- Add support for printf() in guest code and covert all guest asserts
to use printf-based reporting
- Clean up the PMU event filter test and add new testcases
- Include x86 selftests in the KVM x86 MAINTAINERS entry"

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 updates for Linux 6.6
- Add support for TLB range invalidation of Stage-2 page tables,
avoiding unnecessary invalidations. Systems that do not implement
range invalidation still rely on a full invalidation when dealing
with large ranges.
- Add infrastructure for forwarding traps taken from a L2 guest to
the L1 guest, with L0 acting as the dispatcher, another baby step
towards the full nested support.
- Simplify the way we deal with the (long deprecated) 'CPU target',
resulting in a much needed cleanup.
- Fix another set of PMU bugs, both on the guest and host sides,
as we seem to never have any shortage of those...
- Relax the alignment requirements of EL2 VA allocations for
non-stack allocations, as we were otherwise wasting a lot of that
precious VA space.
- The usual set of non-functional cleanups, although I note the lack
of spelling fixes...

Huang Shijie reports that, when profiling a guest from the host
with a number of events that exceeds the number of available
counters, the reported counts are wildly inaccurate. Without
the counter oversubscription, the reported counts are correct.
Their investigation indicates that upon counter rotation (which
takes place on the back of a timer interrupt), we fail to
re-apply the guest EL0 enabling, leading to the counting of host
events instead of guest events.
In order to solve this, add yet another hook between the host PMU
driver and KVM, re-applying the guest EL0 configuration if the
right conditions apply (the host is VHE, we are in interrupt
context, and we interrupted a running vcpu). This triggers a new
vcpu request which will apply the correct configuration on guest
reentry.
With this, we have the correct counts, even when the counters are
oversubscribed.

Currently the Kconfig fragments in kernel/configs and arch/*/configs
that aren't used internally aren't discoverable through "make help",
which consists of hard-coded lists of config fragments. Instead, list
all the fragment targets that have a "# Help: " comment prefix so the
targets can be generated dynamically.
Add logic to the Makefile to search for and display the fragment and
comment. Add comments to fragments that are intended to be direct targets.

Now that we can dispatch all VFP and iWMMXT related undef exceptions
using undef hooks implemented in C code, we no longer need the asm entry
code that takes care of this unless we are using FPE, so we can move it
into the FPE entry code. As this means it is ARM only, we can remove the
Thumb2 specific decorations as well.
It also means the non-standard, asm-only calling convention where
returning via LR means failure and returning via R9 means success is now
only used on legacy platforms that lack any kind of function return
prediction, avoiding the associated performance impact.

Define a undef hook to deal with undef exceptions triggered by iwmmxt
instructions that were issued with the coprocessor disabled. This
removes the dependency on the coprocessor dispatch code in entry-armv.S,
which will be made NWFPE-only in a subsequent patch.

Now that the only remaining coprocessor instructions being handled via
the dispatch in entry-armv.S are ones that only exist in a ARM (A32)
encoding, we can simplify the handling of Thumb undef exceptions, and
send them straight to the undefined instruction handlers in C code.
This also means we can drop the code that partially decodes the
instruction to decide whether it is a 16-bit or 32-bit Thumb
instruction: this is all taken care of by the undef hook.

Now that the VFP support code has been reimplemented as a C function
that takes a struct pt_regs pointer and an opcode, we can use the
existing undef_hook framework to deal with undef exceptions triggered by
VFP instructions instead of having special handling in assembler.

En/disabling softirqs from asm code turned out to be trickier than
expected, so vfp_support_entry now returns by tail calling
__local_enable_bh_ip() and passing the same arguments that a C call to
local_bh_enable() would pass. However, this is slightly hacky, as we
don't want to carry our own implementation of local_bh_enable().
So let's bite the bullet, and get rid of the asm logic in
vfp_support_entry that reasons about whether or not to save and/or
reload the VFP state, and about whether or not an FP exception is
pending, and only keep the VFP loading logic as a function that is
callable from C.
Replicate the removed logic in vfp_entry(), and use the exact same
reasoning as in the asm code. To emphasize the correspondence, retain
some of the asm comments in the C version as well.

Feroceon CPUs have a non-standard implementation of VFP which reports
synchronous VFP exceptions using the async VFP flag. This requires a
workaround which is difficult to reconcile with other implementations,
making it tricky to support both versions in a single image.
Since this is a v5 CPU, it is not supported by armhf and so the
likelihood that anybody is using this with recent distros/kernels and
rely on the VFP at the same time is extremely low. So let's just disable
VFP support on these cores, so we can remove the workaround.
This will help future development to support v5 and v6 CPUs with a
single kernel image.

VFP 'bouncing' occurs when the VFP unit cannot complete the execution of
a VFP instruction, either because it is not implemented at all, or
because the values of the arguments are out of range for the hardware
implementation, and the software needs to step in to complete the
operation.
To give some insight in how much certain programs rely on this bouncing,
record the emulation of a VFP instruction in perf's emulation-faults
counter.
This can be used like so
perf stat -e emulation-faults ./testfloat -all2
and the output will be something like
Performance counter stats for './testfloat -all2':

Arm platforms use is_default_overflow_handler() to determine if the
hw_breakpoint code should single-step over the breakpoint trigger or
let the custom handler deal with it.
Since bpf_overflow_handler() currently isn't recognized as a default
handler, attaching a BPF program to a PERF_TYPE_BREAKPOINT event causes
it to keep firing (the instruction triggering the data abort exception
is never skipped). For example:
# bpftrace -e 'watchpoint:0x10000:4:w { print("hit") }' -c ./test
Attaching 1 probe...
hit
hit
[...]
^C
(./test performs a single 4-byte store to 0x10000)
This patch replaces the check with uses_default_overflow_handler(),
which accounts for the bpf_overflow_handler() case by also testing
if one of the perf_event_output functions gets invoked indirectly,
via orig_default_handler.

Pull x86 shadow stack support from Dave Hansen:
"This is the long awaited x86 shadow stack support, part of Intel's
Control-flow Enforcement Technology (CET).
CET consists of two related security features: shadow stacks and
indirect branch tracking. This series implements just the shadow stack
part of this feature, and just for userspace.
The main use case for shadow stack is providing protection against
return oriented programming attacks. It works by maintaining a
secondary (shadow) stack using a special memory type that has
protections against modification. When executing a CALL instruction,
the processor pushes the return address to both the normal stack and
to the special permission shadow stack. Upon RET, the processor pops
the shadow stack copy and compares it to the normal stack copy.
For more information, refer to the links below for the earlier
versions of this patch set"

A control-protection fault is triggered when a control-flow transfer
attempt violates Shadow Stack or Indirect Branch Tracking constraints.
For example, the return address for a RET instruction differs from the copy
on the shadow stack.
There already exists a control-protection fault handler for handling kernel
IBT faults. Refactor this fault handler into separate user and kernel
handlers, like the page fault handler. Add a control-protection handler
for usermode. To avoid ifdeffery, put them both in a new file cet.c, which
is compiled in the case of either of the two CET features supported in the
kernel: kernel IBT or user mode shadow stack. Move some static inline
functions from traps.c into a header so they can be used in cet.c.
Opportunistically fix a comment in the kernel IBT part of the fault
handler that is on the end of the line instead of preceding it.
Keep the same behavior for the kernel side of the fault handler, except for
converting a BUG to a WARN in the case of a #CP happening when the feature
is missing. This unifies the behavior with the new shadow stack code, and
also prevents the kernel from crashing under this situation which is
potentially recoverable.
The control-protection fault handler works in a similar way as the general
protection fault handler. It provides the si_code SEGV_CPERR to the signal
handler.

The x86 Shadow stack feature includes a new type of memory called shadow
stack. This shadow stack memory has some unusual properties, which requires
some core mm changes to function properly.
One of these unusual properties is that shadow stack memory is writable,
but only in limited ways. These limits are applied via a specific PTE
bit combination. Nevertheless, the memory is writable, and core mm code
will need to apply the writable permissions in the typical paths that
call pte_mkwrite(). The goal is to make pte_mkwrite() take a VMA, so
that the x86 implementation of it can know whether to create regular
writable or shadow stack mappings.
But there are a couple of challenges to this. Modifying the signatures of
each arch pte_mkwrite() implementation would be error prone because some
are generated with macros and would need to be re-implemented. Also, some
pte_mkwrite() callers operate on kernel memory without a VMA.
So this can be done in a three step process. First pte_mkwrite() can be
renamed to pte_mkwrite_novma() in each arch, with a generic pte_mkwrite()
added that just calls pte_mkwrite_novma(). Next callers without a VMA can
be moved to pte_mkwrite_novma(). And lastly, pte_mkwrite() and all callers
can be changed to take/pass a VMA.
Start the process by renaming pte_mkwrite() to pte_mkwrite_novma() and
adding the pte_mkwrite() wrapper in linux/pgtable.h. Apply the same
pattern for pmd_mkwrite(). Since not all archs have a pmd_mkwrite_novma(),
create a new arch config HAS_HUGE_PAGE that can be used to tell if
pmd_mkwrite() should be defined. Otherwise in the !HAS_HUGE_PAGE cases the
compiler would not be able to find pmd_mkwrite_novma().
No functional change.

"These are the devicetree updates for Arm and RISC-V based SoCs, mainly
from Qualcomm, NXP/Freescale, Aspeed, TI, Rockchips, Samsung, ST and
Starfive.
Only a few new SoC got added:
- TI AM62P5, a variant of the existing Sitara AM62x family
- Intel Agilex5, an FPGFA platform that includes an Cortex-A76/A55
SoC.
- Qualcomm ipq5018 is used in wireless access points
- Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile phone
platform.
In total, 29 machines get added, which is low because of the summer
break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head. Most of
these are development and reference boards.
Despite not adding a lot of new machines, there are over 700 patches
in total, most of which are cleanups and minor fixes"

Remove the fixed-link node on port@7 as commit ba4aebce23b2 ("ARM: dts:
BCM5301X: Describe switch ports in the main DTS") states it's not
necessary.
Replace the copyright notice with an author notice.
Rename the model name from Asus to ASUS on bcm47094-asus-rt-ac88u.dts.

Each interrupt should be in its own cell. This is much more readable.

BCM53573 has 2 Ethernet interfaces each connected to one of switch ports
in the default design. They both use fixed links.
An exception are Luxul XAP devices that have switch replaced by a single
PHY.

BCM53125 always has 5 ports with GPHYs (for LAN/WAN ports) and 2 IMP
ports. It seems the best place to describe that in the main .dtsi.
Device specific bits can go to device .dts files. This will help
avoiding some code duplication.
