It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to to of_property_read_bool().

It is clearly stated on "Loongson 3A3000/3B3000 processor
user manual vol 2" that
"All access requests using a non-cached algorithm are executed in a
blocking order. That is, before the current read request data is
returned to the processor, all subsequent requests are blocked and issued;
All subsequent requests are blocked until the write request data has been
sent or the issued write request has not received a write reply from the
final receiver."
Which means uncached read/write is strongly ordered. So we won't need this
workaround.
This option was introduced when we add initial support for GS464E, it looks
like a misinterpretation of another section in the manual saying we need
barriers to ensure MMIO order against DMA requests.

Q: Do we have really have write buffer
A: Yes, on newer Loongson processors there is a "store fill buffer"
that will collect *cached* writes, on all Loongson processors
AXI crossbar will buffer all writes.
Q: Then why do we want to remove CPU_HAS_WB?
A: Because CPU_HAS_WB introduces wbflush, which intends to flush
all write reuqests to mmio device. We won't be affected by store
fill buffer because it won't buffer uncached writes. And a regular
memory barrier is sufficient to flush crossbar write buffer.

Previously every write to SMP regisers are followed by nudge_writes,
this incures a huge performance penalty because nudge_writes involves
SYNC, which will be globalized on chip.
Only set off nudge_writes when we really want other cores to see the
result ASAP. Also replace read/write functions to relaxed version because
we don't need extra barriers to protect against DMA.

module_layout manages different types of memory (text, data, rodata, etc.)
in one allocation, which is problematic for some reasons:
1. It is hard to enable CONFIG_STRICT_MODULE_RWX.
2. It is hard to use huge pages in modules (and not break strict rwx).
3. Many archs uses module_layout for arch-specific data, but it is not
obvious how these data are used (are they RO, RX, or RW?)
Improve the scenario by replacing 2 (or 3) module_layout per module with
up to 7 module_memory per module:
MOD_TEXT,
MOD_DATA,
MOD_RODATA,
MOD_RO_AFTER_INIT,
MOD_INIT_TEXT,
MOD_INIT_DATA,
MOD_INIT_RODATA,
and allocating them separately. This adds slightly more entries to
mod_tree (from up to 3 entries per module, to up to 7 entries per
module). However, this at most adds a small constant overhead to
__module_address(), which is expected to be fast.
Various archs use module_layout for different data. These data are put
into different module_memory based on their location in module_layout.
IOW, data that used to go with text is allocated with MOD_MEM_TYPE_TEXT;
data that used to go with data is allocated with MOD_MEM_TYPE_DATA, etc.
module_memory simplifies quite some of the module code. For example,
ARCH_WANTS_MODULES_DATA_IN_VMALLOC is a lot cleaner, as it just uses a
different allocator for the data. kernel/module/strict_rwx.c is also
much cleaner with module_memory.

Before commit 076cbf5d2163 ("x86/xen: don't let xen_pv_play_dead()
return"), in Xen, when a previously offlined CPU was brought back
online, it unexpectedly resumed execution where it left off in the
middle of the idle loop.
There were some hacks to make that work, but the behavior was surprising
as do_idle() doesn't expect an offlined CPU to return from the dead (in
arch_cpu_idle_dead()).
Now that Xen has been fixed, and the arch-specific implementations of
arch_cpu_idle_dead() also don't return, give it a __noreturn attribute.
This will cause the compiler to complain if an arch-specific
implementation might return. It also improves code generation for both
caller and callee.
Also fixes the following warning:
vmlinux.o: warning: objtool: do_idle+0x25f: unreachable instruction

play_dead() doesn't return. Make that more explicit with a BUG().
BUG() is preferable to unreachable() because BUG() is a more explicit
failure mode and avoids undefined behavior like falling off the edge of
the function into whatever code happens to be next.

Clang is unable to handle the situation that a chunk of inline
assembly ends with a compat branch instruction and then compiler
generates another control transfer instruction immediately after
this compat branch. The later instruction will end up in forbidden
slot and cause exception.
Workaround by add a option to control the use of compact branch.
Currently it's selected by CC_IS_CLANG and hopefully we can change
it to a version check in future if clang manages to fix it.

"A double-word or a variable shift may give an incorrect result if

For DADDI errata we just workaround by disable immediate operation
for BPF_ADD / BPF_SUB to avoid generation of DADDIU.
All other use cases in JIT won't cause overflow thus they are all safe.

Currently, out of every Ralink SoC, only the dt-binding of the MT7621 SoC
uses pinctrl. Because of this, PINCTRL is not selected at all. Make
SOC_MT7621 select PINCTRL.
Remove PINCTRL_MT7621, enabling it for the MT7621 SoC will be handled under
the PINCTRL_MT7621 option.

In c0_compare_int_usable we clear compare interrupt by write value
just read out from counter to compare register.
However sometimes if those all instructions are graduated together
then it's possible that at the time compare register is written, the
counter haven't progressed, thus the interrupt is triggered again.
It also applies to QEMU that instructions is executed significantly
faster then counter.
Offset the value used to clear interrupt by one to prevent that happen.

CP0_CMGCRBASE is not always available on CPS enabled system
such as early proAptiv.
For early SMP bring up where we can't safely access memeory,
we patch the entry of CPS NMI vector to inject CMGCR address
directly into register during early core bringup.
For VPE bringup as the core is already coherenct at that point
we just read the variable to obtain the address.

Pull kvm updates from Paolo Bonzini:
"ARM:
- Provide a virtual cache topology to the guest to avoid
inconsistencies with migration on heterogenous systems. Non secure
software has no practical need to traverse the caches by set/way in
the first place
- Add support for taking stage-2 access faults in parallel. This was
an accidental omission in the original parallel faults
implementation, but should provide a marginal improvement to
machines w/o FEAT_HAFDBS (such as hardware from the fruit company)
- A preamble to adding support for nested virtualization to KVM,
including vEL2 register state, rudimentary nested exception
handling and masking unsupported features for nested guests
- Fixes to the PSCI relay that avoid an unexpected host SVE trap when
resuming a CPU when running pKVM
- VGIC maintenance interrupt support for the AIC
- Improvements to the arch timer emulation, primarily aimed at
reducing the trap overhead of running nested
- Add CONFIG_USERFAULTFD to the KVM selftests config fragment in the
interest of CI systems
- Avoid VM-wide stop-the-world operations when a vCPU accesses its
own redistributor
- Serialize when toggling CPACR_EL1.SMEN to avoid unexpected
exceptions in the host
- Aesthetic and comment/kerneldoc fixes
- Drop the vestiges of the old Columbia mailing list and add [Oliver]
as co-maintainer
RISC-V:
- Fix wrong usage of PGDIR_SIZE instead of PUD_SIZE
- Correctly place the guest in S-mode after redirecting a trap to the
guest
- Redirect illegal instruction traps to guest
- SBI PMU support for guest
s390:
- Sort out confusion between virtual and physical addresses, which
currently are the same on s390
- A new ioctl that performs cmpxchg on guest memory
- A few fixes
x86:
- Change tdp_mmu to a read-only parameter
- Separate TDP and shadow MMU page fault paths
- Enable Hyper-V invariant TSC control
- Fix a variety of APICv and AVIC bugs, some of them real-world, some
of them affecting architecurally legal but unlikely to happen in
practice
- Mark APIC timer as expired if its in one-shot mode and the count
underflows while the vCPU task was being migrated
- Advertise support for Intel's new fast REP string features
- Fix a double-shootdown issue in the emergency reboot code
- Ensure GIF=1 and disable SVM during an emergency reboot, i.e. give
SVM similar treatment to VMX
- Update Xen's TSC info CPUID sub-leaves as appropriate
- Add support for Hyper-V's extended hypercalls, where "support" at
this point is just forwarding the hypercalls to userspace
- Clean up the kvm->lock vs. kvm->srcu sequences when updating the
PMU and MSR filters
- One-off fixes and cleanups
- Fix and cleanup the range-based TLB flushing code, used when KVM is
running on Hyper-V
- Add support for filtering PMU events using a mask. If userspace
wants to restrict heavily what events the guest can use, it can now
do so without needing an absurd number of filter entries
- Clean up KVM's handling of "PMU MSRs to save", especially when vPMU
support is disabled
- Add PEBS support for Intel Sapphire Rapids
- Fix a mostly benign overflow bug in SEV's
send|receive_update_data()
- Move several SVM-specific flags into vcpu_svm
x86 Intel:
- Handle NMI VM-Exits before leaving the noinstr region
- A few trivial cleanups in the VM-Enter flows
- Stop enabling VMFUNC for L1 purely to document that KVM doesn't
support EPTP switching (or any other VM function) for L1
- Fix a crash when using eVMCS's enlighted MSR bitmaps
Generic:
- Clean up the hardware enable and initialization flow, which was
scattered around multiple arch-specific hooks. Instead, just let
the arch code call into generic code. Both x86 and ARM should
benefit from not having to fight common KVM code's notion of how to
do initialization
- Account allocations in generic kvm_arch_alloc_vm()
- Fix a memory leak if coalesced MMIO unregistration fails
selftests:
- On x86, cache the CPU vendor (AMD vs. Intel) and use the info to
emit the correct hypercall instruction instead of relying on KVM to
patch in VMMCALL
- Use TAP interface for kvm_binary_stats_test and tsc_msrs_test"

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"
[ Geert Uytterhoeven points out that that last sentence isn't true, and
that there's a pending report that has a fix that is queued up - Linus ]
