Pull interrupt subsystem updates from Thomas Gleixner:
"Core:
- Provide a new mechanism to create interrupt domains. The existing
interfaces have already too many parameters and it's a pain to
expand any of this for new required functionality.
The new function takes a pointer to a data structure as argument.
The data structure combines all existing parameters and allows for
easy extension.
The first extension for this is to handle the instantiation of
generic interrupt chips at the core level and to allow drivers to
provide extra init/exit callbacks.
This is necessary to do the full interrupt chip initialization
before the new domain is published, so that concurrent usage sites
won't see a half initialized interrupt domain. Similar problems
exist on teardown.
This has turned out to be a real problem due to the deferred and
parallel probing which was added in recent years.
Handling this at the core level allows to remove quite some accrued
boilerplate code in existing drivers and avoids horrible
workarounds at the driver level.
- The usual small improvements all over the place
Drivers:
- Add support for LAN966x OIC and RZ/Five SoC
- Split the STM ExtI driver into a microcontroller and a SMP version
to allow building the latter as a module for multi-platform
kernels
- Enable MSI support for Armada 370XP on platforms which do not
support IPIs
- The usual small fixes and enhancements all over the place"

Pull MM updates from Andrew Morton:
- In the series "mm: Avoid possible overflows in dirty throttling" Jan
Kara addresses a couple of issues in the writeback throttling code.
These fixes are also targetted at -stable kernels.
- Ryusuke Konishi's series "nilfs2: fix potential issues related to
reserved inodes" does that. This should actually be in the
mm-nonmm-stable tree, along with the many other nilfs2 patches. My
bad.
- More folio conversions from Kefeng Wang in the series "mm: convert to
folio_alloc_mpol()"
- Kemeng Shi has sent some cleanups to the writeback code in the series
"Add helper functions to remove repeated code and improve readability
of cgroup writeback"
- Kairui Song has made the swap code a little smaller and a little
faster in the series "mm/swap: clean up and optimize swap cache
index".
- In the series "mm/memory: cleanly support zeropage in
vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David
Hildenbrand has reworked the rather sketchy handling of the use of
the zeropage in MAP_SHARED mappings. I don't see any runtime effects
here - more a cleanup/understandability/maintainablity thing.
- Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling
of higher addresses, for aarch64. The (poorly named) series is
"Restructure va_high_addr_switch".
- The core TLB handling code gets some cleanups and possible slight
optimizations in Bang Li's series "Add update_mmu_tlb_range() to
simplify code".
- Jane Chu has improved the handling of our
fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in
the series "Enhance soft hwpoison handling and injection".
- Jeff Johnson has sent a billion patches everywhere to add
MODULE_DESCRIPTION() to everything. Some landed in this pull.
- In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang
has simplified migration's use of hardware-offload memory copying.
- Yosry Ahmed performs more folio API conversions in his series "mm:
zswap: trivial folio conversions".
- In the series "large folios swap-in: handle refault cases first",
Chuanhua Han inches us forward in the handling of large pages in the
swap code. This is a cleanup and optimization, working toward the end
objective of full support of large folio swapin/out.
- In the series "mm,swap: cleanup VMA based swap readahead window
calculation", Huang Ying has contributed some cleanups and a possible
fixlet to his VMA based swap readahead code.
- In the series "add mTHP support for anonymous shmem" Baolin Wang has
taught anonymous shmem mappings to use multisize THP. By default this
is a no-op - users must opt in vis sysfs controls. Dramatic
improvements in pagefault latency are realized.
- David Hildenbrand has some cleanups to our remaining use of
page_mapcount() in the series "fs/proc: move page_mapcount() to
fs/proc/internal.h".
- David also has some highmem accounting cleanups in the series
"mm/highmem: don't track highmem pages manually".
- Build-time fixes and cleanups from John Hubbard in the series
"cleanups, fixes, and progress towards avoiding "make headers"".
- Cleanups and consolidation of the core pagemap handling from Barry
Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers
and utilize them".
- Lance Yang's series "Reclaim lazyfree THP without splitting" has
reduced the latency of the reclaim of pmd-mapped THPs under fairly
common circumstances. A 10x speedup is seen in a microbenchmark.
It does this by punting to aother CPU but I guess that's a win unless
all CPUs are pegged.
- hugetlb_cgroup cleanups from Xiu Jianfeng in the series
"mm/hugetlb_cgroup: rework on cftypes".
- Miaohe Lin's series "Some cleanups for memory-failure" does just that
thing.
- Someone other than SeongJae has developed a DAMON feature in Honggyu
Kim's series "DAMON based tiered memory management for CXL memory".
This adds DAMON features which may be used to help determine the
efficiency of our placement of CXL/PCIe attached DRAM.
- DAMON user API centralization and simplificatio work in SeongJae
Park's series "mm/damon: introduce DAMON parameters online commit
function".
- In the series "mm: page_type, zsmalloc and page_mapcount_reset()"
David Hildenbrand does some maintenance work on zsmalloc - partially
modernizing its use of pageframe fields.
- Kefeng Wang provides more folio conversions in the series "mm: remove
page_maybe_dma_pinned() and page_mkclean()".
- More cleanup from David Hildenbrand, this time in the series
"mm/memory_hotplug: use PageOffline() instead of PageReserved() for
!ZONE_DEVICE". It "enlightens memory hotplug more about PageOffline()
pages" and permits the removal of some virtio-mem hacks.
- Barry Song's series "mm: clarify folio_add_new_anon_rmap() and
__folio_add_anon_rmap()" is a cleanup to the anon folio handling in
preparation for mTHP (multisize THP) swapin.
- Kefeng Wang's series "mm: improve clear and copy user folio"
implements more folio conversions, this time in the area of large
folio userspace copying.
- The series "Docs/mm/damon/maintaier-profile: document a mailing tool
and community meetup series" tells people how to get better involved
with other DAMON developers. From SeongJae Park.
- A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does
that.
- David Hildenbrand sends along more cleanups, this time against the
migration code. The series is "mm/migrate: move NUMA hinting fault
folio isolation + checks under PTL".
- Jan Kara has found quite a lot of strangenesses and minor errors in
the readahead code. He addresses this in the series "mm: Fix various
readahead quirks".
- SeongJae Park's series "selftests/damon: test DAMOS tried regions and
{min,max}_nr_regions" adds features and addresses errors in DAMON's
self testing code.
- Gavin Shan has found a userspace-triggerable WARN in the pagecache
code. The series "mm/filemap: Limit page cache size to that supported
by xarray" addresses this. The series is marked cc:stable.
- Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations
and cleanup" cleans up and slightly optimizes KSM.
- Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of
code motion. The series (which also makes the memcg-v1 code
Kconfigurable) are "mm: memcg: separate legacy cgroup v1 code and put
under config option" and "mm: memcg: put cgroup v1-specific memcg
data under CONFIG_MEMCG_V1"
- Dan Schatzberg's series "Add swappiness argument to memory.reclaim"
adds an additional feature to this cgroup-v2 control file.
- The series "Userspace controls soft-offline pages" from Jiaqi Yan
permits userspace to stop the kernel's automatic treatment of
excessive correctable memory errors. In order to permit userspace to
monitor and handle this situation.
- Kefeng Wang's series "mm: migrate: support poison recover from
migrate folio" teaches the kernel to appropriately handle migration
from poisoned source folios rather than simply panicing.
- SeongJae Park's series "Docs/damon: minor fixups and improvements"
does those things.
- In the series "mm/zsmalloc: change back to per-size_class lock"
Chengming Zhou improves zsmalloc's scalability and memory
utilization.
- Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for
pinning memfd folios" makes the GUP code use FOLL_PIN rather than
bare refcount increments. So these paes can first be moved aside if
they reside in the movable zone or a CMA block.
- Andrii Nakryiko has added a binary ioctl()-based API to
/proc/pid/maps for much faster reading of vma information. The series
is "query VMAs from /proc/<pid>/maps".
- In the series "mm: introduce per-order mTHP split counters" Lance
Yang improves the kernel's presentation of developer information
related to multisize THP splitting.
- Michael Ellerman has developed the series "Reimplement huge pages
without hugepd on powerpc (8xx, e500, book3s/64)". This permits
userspace to use all available huge page sizes.
- In the series "revert unconditional slab and page allocator fault
injection calls" Vlastimil Babka removes a performance-affecting and
not very useful feature from slab fault injection.

- Add support for KVM_DIRTY_LOG_INITIALLY_SET
- Add perf kvm-stat support for loongarch
RISC-V:
- Redirect AMO load/store access fault traps to guest
- perf kvm stat support
- Use guest files for IMSIC virtualization, when available
s390:
- Assortment of tiny fixes which are not time critical
x86:
- Fixes for Xen emulation
- Add a global struct to consolidate tracking of host values, e.g.
EFER
- Add KVM_CAP_X86_APIC_BUS_CYCLES_NS to allow configuring the
effective APIC bus frequency, because TDX
- Print the name of the APICv/AVIC inhibits in the relevant
tracepoint
- Clean up KVM's handling of vendor specific emulation to
consistently act on "compatible with Intel/AMD", versus checking
for a specific vendor
- Drop MTRR virtualization, and instead always honor guest PAT on
CPUs that support self-snoop
- Update to the newfangled Intel CPU FMS infrastructure
- Don't advertise IA32_PERF_GLOBAL_OVF_CTRL as an MSR-to-be-saved, as
it reads '0' and writes from userspace are ignored
- Misc cleanups
x86 - MMU:
- Small cleanups, renames and refactoring extracted from the upcoming
Intel TDX support
- Don't allocate kvm_mmu_page.shadowed_translation for shadow pages
that can't hold leafs SPTEs
- Unconditionally drop mmu_lock when allocating TDP MMU page tables
for eager page splitting, to avoid stalling vCPUs when splitting
huge pages
- Bug the VM instead of simply warning if KVM tries to split a SPTE
that is non-present or not-huge. KVM is guaranteed to end up in a
broken state because the callers fully expect a valid SPTE, it's
all but dangerous to let more MMU changes happen afterwards
x86 - AMD:
- Make per-CPU save_area allocations NUMA-aware
- Force sev_es_host_save_area() to be inlined to avoid calling into
an instrumentable function from noinstr code
- Base support for running SEV-SNP guests. API-wise, this includes a
new KVM_X86_SNP_VM type, encrypting/measure the initial image into
guest memory, and finalizing it before launching it. Internally,
there are some gmem/mmu hooks needed to prepare gmem-allocated
pages before mapping them into guest private memory ranges
This includes basic support for attestation guest requests, enough
to say that KVM supports the GHCB 2.0 specification
There is no support yet for loading into the firmware those signing
keys to be used for attestation requests, and therefore no need yet
for the host to provide certificate data for those keys.
To support fetching certificate data from userspace, a new KVM exit
type will be needed to handle fetching the certificate from
userspace.
An attempt to define a new KVM_EXIT_COCO / KVM_EXIT_COCO_REQ_CERTS
exit type to handle this was introduced in v1 of this patchset, but
is still being discussed by community, so for now this patchset
only implements a stub version of SNP Extended Guest Requests that
does not provide certificate data
x86 - Intel:
- Remove an unnecessary EPT TLB flush when enabling hardware
- Fix a series of bugs that cause KVM to fail to detect nested
pending posted interrupts as valid wake eents for a vCPU executing
HLT in L2 (with HLT-exiting disable by L1)
- KVM: x86: Suppress MMIO that is triggered during task switch
emulation
Explicitly suppress userspace emulated MMIO exits that are
triggered when emulating a task switch as KVM doesn't support
userspace MMIO during complex (multi-step) emulation
Silently ignoring the exit request can result in the
WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace
for some other reason prior to purging mmio_needed
See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write
exits if emulator detects exception") for more details on KVM's
limitations with respect to emulated MMIO during complex emulator
flows
Generic:
- Rename the AS_UNMOVABLE flag that was introduced for KVM to
AS_INACCESSIBLE, because the special casing needed by these pages
is not due to just unmovability (and in fact they are only
unmovable because the CPU cannot access them)
- New ioctl to populate the KVM page tables in advance, which is
useful to mitigate KVM page faults during guest boot or after live
migration. The code will also be used by TDX, but (probably) not
through the ioctl
- Enable halt poll shrinking by default, as Intel found it to be a
clear win
- Setup empty IRQ routing when creating a VM to avoid having to
synchronize SRCU when creating a split IRQCHIP on x86
- Rework the sched_in/out() paths to replace kvm_arch_sched_in() with
a flag that arch code can use for hooking both sched_in() and
sched_out()
- Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
truncating a bogus value from userspace, e.g. to help userspace
detect bugs
- Mark a vCPU as preempted if and only if it's scheduled out while in
the KVM_RUN loop, e.g. to avoid marking it preempted and thus
writing guest memory when retrieving guest state during live
migration blackout
Selftests:
- Remove dead code in the memslot modification stress test
- Treat "branch instructions retired" as supported on all AMD Family
17h+ CPUs
- Print the guest pseudo-RNG seed only when it changes, to avoid
spamming the log for tests that create lots of VMs
- Make the PMU counters test less flaky when counting LLC cache
misses by doing CLFLUSH{OPT} in every loop iteration"

There is a report that iowq executed getsockopt never completes. The
reason being that io_uring_cmd_sock() can return a positive result, and
io_uring_cmd() propagates it back to core io_uring, instead of IOU_OK.
In case of io_wq_submit_work(), the request will be dropped without
completing it.
The offending code was introduced by a hack in
a9c3eda7eada9 ("io_uring: fix submission-failure handling for uring-cmd"),
however it was fine until getsockopt was introduced and started
returning positive results.
The right solution is to always return IOU_OK, since
e0b23d9953b0c ("io_uring: optimise ltimeout for inline execution"),
we should be able to do it without problems, however for the sake of
backporting and minimising side effects, let's keep returning negative
return codes and otherwise do IOU_OK.

RELR as a relocation packing format for relative relocations for
reducing the size of relative relocation records. In a position
independent executable there are often many relative relocation
records, and our vmlinux is a PIE.
The LLD linker (since 17.0.0) and the BFD linker (since 2.43) supports
packing the relocations in the RELR format for LoongArch, with the flag
-z pack-relative-relocs.
Commits 5cf896fb6be3eff ("arm64: Add support for relocating the kernel
with RELR relocations") and ccb2d173b983984bfa ("Makefile: use -z
pack-relative-relocs") have already added the framework to use RELR.
We just need to wire it up and process the RELR relocation records in
relocate_relative() in addition to the RELA relocation records.
A ".p2align 3" directive is added to la_abs macro or the BFD linker
cannot pack the relocation records against the .la_abs section (the
". = ALIGN(8);" directive in vmlinux.lds.S is too late in the linking
process).
With defconfig and CONFIG_RELR vmlinux.efi is 2.1 MiB (6%) smaller, and
vmlinuz.efi (using gzip compression) is 384 KiB (2.8%) smaller.

Hibernation assumes the memory layout after resume be the same as that
before sleep, so it expects the kernel is loaded at the same position.
To achieve this goal we automatically disable KASLR if user explicitly
requests hibernation via the "resume=" command line. Since "nohibernate"
and "noresume" have higher priorities than "resume=", we only disable
KASLR if there is no "nohibernate" and "noresume".

Most LoongArch 64 machines are using custom "SADR" ACPI extension to
perform ACPI S3 sleep. However the standard ACPI way to perform sleep
is to write a value to ACPI PM1/SLEEP_CTL register, and this is never
supported properly in kernel.
Add standard S3 sleep by providing a default DoSuspend function which
calls ACPI's acpi_enter_sleep_state() routine when SADR is not provided
by the firmware.
Also fix suspend assembly code so that ra is set properly before go
into sleep routine. (Previously linked address of jirl was set to a0,
some firmware do require return address in a0 but it's already set with
la.pcrel before).

DMW3 is unused by kernel now, however firmware may leave garbage in them

Add support of kernel stack offset randomization while handling syscall,
the offset is defaultly limited by KSTACK_OFFSET_MAX().
In order to avoid triggering stack canaries (due to __builtin_alloca())
and slowing down the entry path, use __no_stack_protector attribute to
disable stack protector for do_syscall() at function level.
With this patch, the REPORT_STACK test show that:
`loongarch64 bits of stack entropy: 7`

Some drivers want to use cpu_logical_map(), early_cpu_to_node() and some
other CPU mapping APIs, even if we use "nr_cpus=1" to hard limit the CPU
number. This is strongly required for the multi-bridges machines.
Currently, we stop parsing the MADT if the nr_cpus limit is reached, but
to achieve the above goal we should always enumerate the MADT table and
setup logical-physical CPU mapping whether there is a nr_cpus limit.
Rework the MADT enumeration:
1. Define a flag "cpu_enumerated" to distinguish the first enumeration
(cpu_enumerated=0) and the physical hotplug case (cpu_enumerated=1)
for set_processor_mask().
2. If cpu_enumerated=0, stop parsing only when NR_CPUS limit is reached,
so we can setup logical-physical CPU mapping; if cpu_enumerated=1,
stop parsing when nr_cpu_ids limit is reached, so we can avoid some
runtime bugs. Once logical-physical CPU mapping is setup, we will let
cpu_enumerated=1.
3. Use find_first_zero_bit() instead of cpumask_next_zero() to find the
next zero bit (free logical CPU id) in the cpu_present_mask, because
cpumask_next_zero() will stop at nr_cpu_ids.
4. Only touch cpu_possible_mask if cpu_enumerated=0, this is in order to
avoid some potential crashes, because cpu_possible_mask is marked as
__ro_after_init.
5. In prefill_possible_map(), clear cpu_present_mask bits greater than
nr_cpu_ids, in order to avoid a CPU be "present" but not "possible".

Chromium sandbox apparently wants to deny statx [1] so it could properly
inspect arguments after the sandboxed process later falls back to fstat.
Because there's currently not a "fd-only" version of statx, so that the
sandbox has no way to ensure the path argument is empty without being
able to peek into the sandboxed process's memory. For architectures able
to do newfstatat though, glibc falls back to newfstatat after getting
-ENOSYS for statx, then the respective SIGSYS handler [2] takes care of
inspecting the path argument, transforming allowed newfstatat's into
fstat instead which is allowed and has the same type of return value.
But, as LoongArch is the first architecture to not have fstat nor
newfstatat, the LoongArch glibc does not attempt falling back at all
when it gets -ENOSYS for statx -- and you see the problem there!
Actually, back when the LoongArch port was under review, people were
aware of the same problem with sandboxing clone3 [3], so clone was
eventually kept. Unfortunately it seemed at that time no one had noticed
statx, so besides restoring fstat/newfstatat to LoongArch uapi (and
postponing the problem further), it seems inevitable that we would need
to tackle seccomp deep argument inspection.
However, this is obviously a decision that shouldn't be taken lightly,
so we just restore fstat/newfstatat by defining __ARCH_WANT_NEW_STAT
in unistd.h. This is the simplest solution for now, and so we hope the
community will tackle the long-standing problem of seccomp deep argument
inspection in the future [4][5].
Also add "newstat" to syscall_abis_64 in Makefile.syscalls due to
upstream asm-generic changes.

Raw NAND changes;
The Freescale MXC driver has been converted to the newer ->exec_op()
interface. The meson driver now supports handling the boot ROM area with
very specific ECC needs. Support for the iMX8QXP has been added to the
GPMI driver. The lpx32xx driver now can get the DMA channels using DT
entries. The Qcom binding has been improved to be more future proof by
Rob. And then there is the usual load of misc and minor changes.
SPI-NAND changes:
The Macronix vendor driver has been improved to support an extended ID
to avoid conflicting with older devices after an ID reuse issue.

SPI NOR changes for 6.11
Notable changes:
- Drop support for Xilinx S3AN flashes. These flashes are for the very
old Xilinx Spartan 3 FPGAs and they need some awkward code in the core
to support. Drop support for these flashes, along with the special
handling we needed for them in the core like non-power-of-2 page size
handling and the .setup() callback.
- Fix regression for old w25q128 flashes without SFDP tables. Commit
83e824a4a595 ("mtd: spi-nor: Correct flags for Winbond w25q128")
dropped support for such devices under the assumption that they aren't
being used anymore. Users have now surfaced [0] so fix the regression
by supporting both kind of devices.
- Core cleanups including removal of SPI_NOR_NO_FR flag and
simplification of spi_nor_get_flash_info().

Pull i2c fixes from Wolfram Sang:
"The I2C core gains documentation updates for the testunit, a cleanup
regarding unneeded 'driver_data' and more sanity checks in the char
device.
For the host drivers, this release includes significant updates, with
the primary change being the renaming from "master/slave" to
"controller/target" to adhere to I2C v7 and SMBus 3.2 standards.
New Support:
- Added support for Intel Arrow Lake-H
- Added I2C support in the Arioha SoC by linking the Mediatek I2C
controller
Cleanups:
- Added the MODULE_DESCRIPTION() macro, resolving a modpost warning
in the ALi 1563 Southbridge driver.
- Constified the regmap_config declaration in the i2c-designware
driver.
- Improved the coding style in the Renesas R-Car driver by removing
unnecessary semicolons after brackets.
General improvements:
- In the OMAP device, replaced NOIRQ_SYSTEM_SLEEP_PM_OPS with
RUNTIME_PM_OPS to enable waking up the controller during suspend()
before suspend_noirq() kicks in.
- Improved logging in the Xilinx driver.
- Added a warning (WARN()) in the Renesas R-Car driver for spurious
interrupts.
DTS Changes:
- Removed address-cell and size-cell from the Atmel at91sam, nVidia
Tegra 20, and Samsung S3c2410 devices.
- Fixed Texas Instruments OMAP4 I2C controller to comply with the
i2c-controller.yaml schema.
- Improved indentation in DTS examples for several I2C devices.

Pull char / misc and other driver updates from Greg KH:
"Here is the "big" set of char/misc and other driver subsystem changes
for 6.11-rc1. Nothing major in here, just loads of new drivers and
updates. Included in here are:
- IIO api updates and new drivers added
- wait_interruptable_timeout() api cleanups for some drivers
- MODULE_DESCRIPTION() additions for loads of drivers
- parport out-of-bounds fix
- interconnect driver updates and additions
- mhi driver updates and additions
- w1 driver fixes

All of these, EXCEPT for the final Kconfig build fix for 32bit
systems, have been in linux-next for a while with no reported issues.
The Kconfig fixup went in 29 hours ago, so might have missed the
latest linux-next, but was acked by everyone involved"

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH:
"This is the "big" staging driver update for 6.11-rc1. Not really all
that much happened this release cycle, just lots of tiny cleanups,
overall about 3000 lines removed, so the cleanups were worth it.
Included in here are:
- loads of rtl8723bs driver cleanups
- lots of rtl8192e driver cleanups
- vc04_services reworks and cleanups as that codebase gets slowly
evolved into something that will make it into the "real" part of
the kernel hopefully soon.
- other tiny staging driver cleanups
All of these have been in linux-next for a while with no reported
issues"
