selftests/powerpc: Suppress -Wmaybe-uninitialized with GCC 15
GCC 15 reports the below false positive '-Wmaybe-uninitialized' warning
in vphn_unpack_associativity() when building the powerpc selftests.

| ^~~~~~~~~
cc1: all warnings being treated as errors
When vphn_unpack_associativity() is called from hcall_vphn() in kernel
the error is not seen while building vphn.c during kernel compilation.
This is because the top level Makefile includes '-fno-strict-aliasing'
flag always.
The issue here is that GCC 15 emits '-Wmaybe-uninitialized' due to type
punning between __be64[] and __b16* when accessing the buffer via
be16_to_cpup(). The underlying object is fully initialized but GCC 15
fails to track the aliasing due to the strict aliasing violation here.
Please refer [1] and [2]. This results in a false positive warning which
is promoted to an error under '-Werror'. This problem is not seen when
the compilation is performed with GCC 13 and 14. An issue [1] has also
been created on GCC bugzilla.
The selftest compiles fine with '-fno-strict-aliasing'. Since this GCC
flag is used to compile vphn.c in kernel too, the same flag should be
used to build vphn tests when compiling vphn.c in the selftest as well.
Fix this by including '-fno-strict-aliasing' during vphn.c compilation
in the selftest. This keeps the build working while limiting the scope
of the suppression to building vphn tests.

powerpc/xive: rework xive_find_target_in_mask()
Switch the function to using modern cpumask API and drop most of the housekeeping code.

powerpc/crash: Update backup region offset in elfcorehdr on memory hotplug
When elfcorehdr is prepared for kdump, the program header representing
the first 64 KB of memory is expected to have its offset point to the
backup region. This is required because purgatory copies the first 64 KB
of the crashed kernel memory to this backup region following a kernel
crash. This allows the capture kernel to use the first 64 KB of memory
to place the exception vectors and other required data.
When elfcorehdr is recreated due to memory hotplug, the offset of
the program header representing the first 64 KB is not updated.
As a result, the capture kernel exports the first 64 KB at offset
0, even though the data actually resides in the backup region.
Fix this by calling sync_backup_region_phdr() to update the program
header offset in the elfcorehdr created during memory hotplug.
sync_backup_region_phdr() works for images loaded via the
kexec_file_load syscall. However, it does not work for kexec_load,
because image->arch.backup_start is not initialized in that case.
So introduce machine_kexec_post_load() to process the elfcorehdr
prepared by kexec-tools and initialize image->arch.backup_start for
kdump images loaded via kexec_load syscall.
Rename update_backup_region_phdr() to sync_backup_region_phdr() and
extend it to synchronize the backup region offset between the kdump
image and the ELF core header. The helper now supports updating either
the kdump image from the ELF program header or updating the ELF program
header from the kdump image, avoiding code duplication.
Define ARCH_HAS_KIMAGE_ARCH and struct kimage_arch when
CONFIG_KEXEC_FILE or CONFIG_CRASH_DUMP is enabled so that
kimage->arch.backup_start is available with the kexec_load system call.
This patch depends on the patch titled
"powerpc/crash: fix backup region offset update to elfcorehdr".

powerpc/crash: fix backup region offset update to elfcorehdr
update_backup_region_phdr() in file_load_64.c iterates over all the
program headers in the kdump kernel’s elfcorehdr and updates the
p_offset of the program header whose physical address starts at 0.
However, the loop logic is incorrect because the program header pointer
is not updated during iteration. Since elfcorehdr typically contains
PT_NOTE entries first, the PT_LOAD program header with physical address
0 is never reached. As a result, its p_offset is not updated to point to
the backup region.
Because of this behavior, the capture kernel exports the first 64 KB of
the crashed kernel’s memory at offset 0, even though that memory
actually lives in the backup region. When a crash happens, purgatory
copies the first 64 KB of the crashed kernel’s memory into the backup
region so the capture kernel can safely use it.
This has not caused problems so far because the first 64 KB is usually
identical in both the crashed and capture kernels. However, this is
just an assumption and is not guaranteed to always hold true.
Fix update_backup_region_phdr() to correctly update the p_offset of the
program header with a starting physical address of 0 by correcting the
logic used to iterate over the program headers.

powerpc/64s: Add support for huge pfnmaps
This uses _RPAGE_SW2 bit for the PMD and PUDs similar to PTEs.
This also adds support for {pte,pmd,pud}_pgprot helpers needed for
follow_pfnmap APIs.
This allows us to extend the PFN mappings, e.g. PCI MMIO bars where
it can grow as large as 8GB or even bigger, to map at PMD / PUD level.
VFIO PCI core driver already supports fault handling at PMD / PUD level
for more efficient BAR mappings.

powerpc/pgtable-frag: Fix bad page state in pte_frag_destroy
powerpc uses pt_frag_refcount as a reference counter for tracking it's
pte and pmd page table fragments. For PTE table, in case of Hash with
64K pagesize, we have 16 fragments of 4K size in one 64K page.
Patch series [1] "mm: free retracted page table by RCU"
added pte_free_defer() to defer the freeing of PTE tables when
retract_page_tables() is called for madvise MADV_COLLAPSE on shmem
range.
[1]: https://lore.kernel.org/all/7cd843a9-aa80-14f-5eb2-33427363c20@google.com/
pte_free_defer() sets the active flag on the corresponding fragment's
folio & calls pte_fragment_free(), which reduces the pt_frag_refcount.
When pt_frag_refcount reaches 0 (no active fragment using the folio), it
checks if the folio active flag is set, if set, it calls call_rcu to
free the folio, it the active flag is unset then it calls pte_free_now().
Now, this can lead to following problem in a corner case...

The bad page state error occurs when such a folio gets freed (with
active flag set), from do_exit() path in parallel.
... this can happen when the pte fragment was allocated from this folio,
but when all the fragments get freed, the pte_frag_refcount still had some
unused fragments. Now, if this process exits, with such folio as it's cached
pte_frag in mm->context, then during pte_frag_destroy(), we simply call
pagetable_dtor() and pagetable_free(), meaning it doesn't clear the
active flag. This, can lead to the above bug. Since we are anyway in
do_exit() path, then if the refcount is 0, then I guess it should be
ok to simply clear the folio active flag before calling pagetable_dtor()
& pagetable_free().

ARM:
- Correctly handle deeactivation of interrupts that were activated from
LRs. Since EOIcount only denotes deactivation of interrupts that
are not present in an LR, start EOIcount deactivation walk *after*
the last irq that made it into an LR.
- Avoid calling into the stubs to probe for ICH_VTR_EL2.TDS when
pKVM is already enabled -- not only thhis isn't possible (pKVM
will reject the call), but it is also useless: this can only
happen for a CPU that has already booted once, and the capability
will not change.
- Fix a couple of low-severity bugs in our S2 fault handling path,
affecting the recently introduced LS64 handling and the even more
esoteric handling of hwpoison in a nested context
- Address yet another syzkaller finding in the vgic initialisation,
where we would end-up destroying an uninitialised vgic with nasty
consequences
- Address an annoying case of pKVM failing to boot when some of the
memblock regions that the host is faulting in are not page-aligned
- Inject some sanity in the NV stage-2 walker by checking the limits
against the advertised PA size, and correctly report the resulting
faults
PPC:
- Fix a PPC e500 build error due to a long-standing wart that was exposed by
the recent conversion to kmalloc_obj(); rip out all the ugliness that
led to the wart.
RISC-V:
- Prevent speculative out-of-bounds access using array_index_nospec()
in APLIC interrupt handling, ONE_REG regiser access, AIA CSR access,
float register access, and PMU counter access
- Fix potential use-after-free issues in kvm_riscv_gstage_get_leaf(),
kvm_riscv_aia_aplic_has_attr(), and kvm_riscv_aia_imsic_has_attr()
- Fix potential null pointer dereference in kvm_riscv_vcpu_aia_rmw_topei()
- Fix off-by-one array access in SBI PMU
- Skip THP support check during dirty logging
- Fix error code returned for Smstateen and Ssaia ONE_REG interface
- Check host Ssaia extension when creating AIA irqchip
x86:
- Fix cases where CPUID mitigation features were incorrectly marked as
available whenever the kernel used scattered feature words for them.
- Validate _all_ GVAs, rather than just the first GVA, when processing
a range of GVAs for Hyper-V's TLB flush hypercalls.
- Fix a brown paper bug in add_atomic_switch_msr().
- Use hlist_for_each_entry_srcu() when traversing mask_notifier_list,
to fix a lockdep warning; KVM doesn't hold RCU, just irq_srcu.
- Ensure AVIC VMCB fields are initialized if the VM has an in-kernel local
APIC (and AVIC is enabled at the module level).
- Update CR8 write interception when AVIC is (de)activated, to fix a bug
where the guest can run in perpetuity with the CR8 intercept enabled.
- Add a quirk to skip the consistency check on FREEZE_IN_SMM, i.e. to allow
L1 hypervisors to set FREEZE_IN_SMM. This reverts (by default) an
unintentional tightening of userspace ABI in 6.17, and provides some
amount of backwards compatibility with hypervisors who want to freeze
PMCs on VM-Entry.
- Validate the VMCS/VMCB on return to a nested guest from SMM, because
either userspace or the guest could stash invalid values in memory
and trigger the processor's consistency checks.
Generic:
- Remove a subtle pseudo-overlay of kvm_stats_desc, which, aside from being
unnecessary and confusing, triggered compiler warnings due to
-Wflex-array-member-not-at-end.
- Document that vcpu->mutex is take outside of kvm->slots_lock and
kvm->slots_arch_lock, which is intentional and desirable despite being
rather unintuitive.
Selftests:
- Increase the maximum number of NUMA nodes in the guest_memfd selftest to
64 (from 8).

More MM-CID fixes, mostly fixing hangs/races:
- Fix CID hangs due to a race between concurrent forks
- Fix vfork()/CLONE_VM MMCID bug causing hangs
- Remove pointless preemption guard
- Fix CID task list walk performance regression on large systems
by removing the known-flaky and slow counting logic using
for_each_process_thread() in mm_cid_*fixup_tasks_to_cpus(),
and implementing a simple sched_mm_cid::node list instead

Rust fixes for v7.0 (2nd)
Toolchain and infrastructure:
- Remap paths to avoid absolute ones starting with the upcoming Rust
1.95.0 release. This improves build reproducibility, avoids leaking
the exact path and avoids having the same path appear in two forms.
The approach here avoids remapping debug information as well, in
order to avoid breaking tools that used the paths to access source
files, which was the previous attempt that needed to be reverted.
- Allow 'unused_features' lint for the upcoming Rust 1.96.0 release.
While well-intentioned, we do not benefit much from the new lint.
- Emit dependency information into '$(depfile)' directly to avoid
a temporary '.d' file (it was an old approach).
'kernel' crate:
- 'str' module: fix warning under '!CONFIG_BLOCK' by making
'NullTerminatedFormatter' public.
- 'cpufreq' module: suppress false positive Clippy warning.
'pin-init' crate:
- Remove '#[disable_initialized_field_access]' attribute which was
unsound. This means removing the support for structs with unaligned
fields (through the 'repr(packed)' attribute), for now.
And document the load-bearing fact of field accessors (i.e. that they
are required for soundness).
- Replace shadowed return token by 'unsafe'-to-create token in order
to remain sound in the face of the likely upcoming Type Alias Impl
Trait (TAIT) and the next trait solver in upstream Rust.

Pull Rust fixes from Miguel Ojeda:
"Toolchain and infrastructure:
- Remap paths to avoid absolute ones starting with the upcoming Rust
1.95.0 release. This improves build reproducibility, avoids leaking
the exact path and avoids having the same path appear in two forms
The approach here avoids remapping debug information as well, in
order to avoid breaking tools that used the paths to access source
files, which was the previous attempt that needed to be reverted
- Allow 'unused_features' lint for the upcoming Rust 1.96.0 release.
While well-intentioned, we do not benefit much from the new lint
- Emit dependency information into '$(depfile)' directly to avoid a
temporary '.d' file (it was an old approach)
'kernel' crate:
- 'str' module: fix warning under '!CONFIG_BLOCK' by making
'NullTerminatedFormatter' public
- 'cpufreq' module: suppress false positive Clippy warning
'pin-init' crate:
- Remove '#[disable_initialized_field_access]' attribute which was
unsound. This means removing the support for structs with unaligned
fields (through the 'repr(packed)' attribute), for now
And document the load-bearing fact of field accessors (i.e. that
they are required for soundness)
- Replace shadowed return token by 'unsafe'-to-create token in order
to remain sound in the face of the likely upcoming Type Alias Impl
Trait (TAIT) and the next trait solver in upstream Rust"

USB fixes for 7.0-rc4
Here is a large chunk of USB driver fixes for 7.0-rc4. Included in here
are:
- usb gadget reverts due to reported issues, and then a follow-on fix
to hopefully resolve the reported overall problem
- xhci driver fixes
- dwc3 driver fixes
- usb core "killable" bulk message api addition to fix a usbtmc driver
bug where userspace could hang the driver for forever
- small USB driver fixes for reported issues
- new usb device quirks
All except the last USB device quirk change have been in linux-next with
no reported issues. That one came in too late, and is "obviously
correct" :)
