Pull ceph updates from Ilya Dryomov:
"A wide variety of mostly CephFS fixes and cleanups, split between
changes that address edge cases (Sam, Xiubo, Matthew), efficiency
improvements (Max) and AI-assisted hardening (Michael, Jeremy).
One thing that stands out is Alex's change to how CephFS behaves in
NEARFULL scenarios: the long-standing "make all writes synchronous"
behavior has become opt-in. It was always somewhat controversial and
doesn't make much sense for modern deployments; the new default is to
continue normal operation (i.e. buffer writes as MDS allows, etc). The
behavior in case the cluster reaches any FULL state remains the same
as before"

git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, key enhancements focus on reducing inode management
memory overhead, introducing resizable tail sections with unified
pinned allocation, and boosting I/O throughput via parallel
multi-device flushes and asynchronous f2fs_write_end_io() execution.
We also add dynamic device alias reservations to allow on-the-fly
space donation from user partitions.
Alongside these features, critical bug fixes resolve folio race
conditions, lingering dirty flags, dentry and block counter leaks, and
potential deadloops in f2fs_fsync_node_pages(). Additional stability
patches address error-path handling across symlink, sync, and
rename/unlink operations, prevent pinned file fragmentation, and
correct segment migration and free section accounting in
free_segment_range.
Enhancements:
- reduce memory footprint of ino management
- support dynamic reserve/release for device aliasing
- issue multi-device flushes in parallel
- add a way to run f2fs_write_end_io() asynchronously
- support resizable tail section and unify pinned allocation
Bug fixes:
- fix to pass folio->index to f2fs_sanity_check_node_footer()
- fix folio_nr_pages() race after put in large folio invalidate
- fix to clear dirty flag on folio in error path
- accurately adjust free_sections during free_segment_range
- fix to avoid potential deadloop in f2fs_fsync_node_pages()
- fix the error path in symlink, device alias in rename/unlink,
f2fs_sync_fs
- fix to migrate all curseg types during free_segment_range
- fix to avoid pinfile fragment on fragment:{block, segment} mode
- fix valid block count leak on data block allocation failure
- fix dentry folio leak in find_in_level
- reject overlapping move range after len expansion
- fix some bugs related to file pinning, GC functions, i_size
And, the series includes a number of minor bug fixes"

Pull TPM updates from Jarkko Sakkinen:
"The bulk of this is Ross Philipson's TPM enablement for Trenchboot.
That exposes TPM constants, and decouple and improve robustness of
tpm_buf a bit in order to implement a minimal early TPM driver.
Early boot code will call either SKINIT on AMD or GETSEC[SENTER] on
Intel before jumping into kernel's entry point. They re-initalize TPM
PCRs but leave up to the early boot code measure initrd, boot_params
and Trenchboot associated metadata.
The motivation here is just that we would want in future iterations of
the series put our full focus to the x86 part of the review, and call
it a day as per TPM changes. Further, even if Trenchboot turned out to
be empty lottery the worst possible outcome for TPM driver is that
things get cleaned up a bit"

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Use DEBUG_NET_WARN_ON_ONCE() instead of WARN_ON() from the tproxy
datapath, a recent bug found a way to reach WARN_ON from datapath
due to insufficient validation of xt_TPROTO checkentry.
From Fernando F. Mancera.
2) Similar to previous patch to replace WARN_ON_ONCE by
DEBUG_NET_WARN_ON_ONCE() for connlimit. Not known issue, but
since this patch has been around for a while, let's merge it.
Also from Fernando.
3) Move nf_tables harware offload commit path after chain blob
and audit to reduce chances of leaving the hardware in
inconsistent state.
4) Add missing vzeroupper to nf_tables pipapo AVX2 to address
performace degradation to later user of SSE code,
from Eric Biggers.
5) Remove pr_debug() in x_tables extensions, a recent bogus found a
way to print a unsanitized string in xt_IDLETIMER, many of these
pr_debug() calls are there for historical reasons.
6) Use pr_info_ratelimited() in x_tables .checkentry.
7) Fix an imbalance in module refcount due to incorrect override
expression logic with sets. Remove unnecessary clone in control
plane, use the existing expressions provided by set or dynset
expression. Release override expressions only.
8) Tigthen nf_tables device name removal, it is possible to remove
prefix strings with exact device name. From Fernando F. Mancera.
9) Set on the set dead bit earlier, otherwise it is possible to
call .commit on deleted sets. This also addresses the
re-introduction of a bug.

qdisc_get_stab() accepts a user-supplied size table, and
__qdisc_calculate_pkt_len() amplifies qdisc_pkt_len() through the
overhead, the size-table data (u16), and size_log (up to
STAB_SIZE_LOG_MAX). A crafted stab can therefore set qdisc_pkt_len()
to ~1 GiB for an ordinary skb. Per-flow deficit schedulers such as
DRR and ETS replenish one quantum per loop iteration; with a tiny
quantum (1) they spin billions of times under the qdisc lock,
producing a soft lockup / RCU stall as illustrated by vega@nebusec.ai.
Cap the final qdisc_pkt_len() to QDISC_PKT_LEN_MAX so the size-table
amplification cannot drive deficit schedulers into an unbounded loop.
A legitimate size table (e.g. qfq's overhead 999999999, which is
handled by dropping) is still accepted.
Introduce cap QDISC_PKT_LEN_MAX (1 << 20) = 1 MiB which is well above
any legitimate single-skb wire length: the largest current skb->len
is GSO_MAX_SIZE (524280), and an ATM-style size table (53/48 cell tax)
amplifies that to ~578 KB, both comfortably below 1 MiB. At the same
time, 1 MiB bounds the deficit refill loop to ~1M iterations per
packet with quantum=1, which completes in a few milliseconds well
under the demonstrated softlockup threshold (~10^9 iterations).
Conditions to recreate the bug:
- CONFIG_NET_SCHED=y, CONFIG_NET_SCH_DRR=y (or CONFIG_NET_SCH_ETS=y).
- Attach a DRR (or ETS) root qdisc with a crafted TCA_STAB that
amplifies qdisc_pkt_len to ~1 GiB (e.g. size_log=15, data=[32768]).
- Add a class with a tiny quantum of 1 and send one small packet; the
deficit loop spins billions of times under the qdisc lock and trips
the softlockup detector (panic with kernel.softlockup_panic=1).
- Reachable as root or from an unprivileged user in a fresh user+net
namespace (unshare -Urn) with namespace-local CAP_NET_ADMIN.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull more MM updates from Andrew Morton:
- "mm/rmap: index MAP_PRIVATE file-backed folios by anonymous pgoff"
(Lorenzo Stoakes)
Index MAP_PRIVATE file-backed folios by their anonymous page offset
to resolve confusion around reverse mapping for zeroed and CoW'd
file-backed memory.
Use this new VMA anonymous page offset tracking to eliminate index
conflicts and lay the foundation for scalable CoW performance
improvements.
- "promote mapped executable folios after first usage for MGLRU"
(Baolin Wang)
Make MGLRU's protection of mapped executable file folios more
reliable. Follow the classical LRU's logic, promoting mapped
executable file folios after their first usage to give executable
code a better chance to stay in memory and improve workload
performance.
- "mm: vmscan: fix node reclaim ignoring swappiness parameter" (Ridong
Chen)
Fix per-node proactive reclaim interface's ignoring the swappiness
parameter when CONFIG_MEMCG is disabled by consolidating
sc_swappiness() into a single function that checks
proactive_swappiness regardless of kernel configuration.
- "mm/vmscan: reduce lru_lock contention via vmstat-derived
scan-balance cost" (Usama Arif)
Reduce lru_lock contention in the reclaim path by deriving
scan-balance costs from vmstat counters rather than lock-acquired
producer updates.
Read and decay these cost signals on the reclaim side under a
dedicated per-lruvec lock, reducing total LRU lock wait time by over
60% without impacting scan throughput.
- "zram: fix zram issues reported by sashiko" (Sergey Senozhatsky)
Fix two low-risk zram bugs which Sashiko spotted in drive-by review.
- "Honor XA_FLAGS_ACCOUNT in xas_split_alloc() and charge to folio's
memcg" (Zi Yan)
Fix xas_split_alloc() by enabling target folio memcg charging during
splits and adding the missing __GFP_ACCOUNT flag for proper XArray
node memory accounting.
- "selftests/mm: use pattern matching in .gitignore" (Pratyush Mallick)
Replace hardcoded binary names in selftests/mm/.gitignore with a
generic pattern-matching rule to automatically ignore generated test
files and avoid manual updates when adding new tests.
- "mm/page_ext: remove pgdat_page_ext_init()" (Sang-Heon Jeon)
Make the incompatibility between FLATMEM and NUMA explicit in
mm/Kconfig and remove the unused pgdat_page_ext_init() function.
- "zram: fix zstd error paths and add parameter validation" (Haoqin
Huang)
Clean up zram compression backends by removing redundant error
cleanup, adding parameter and dictionary validation, auto-prefixing
algorithm error logs, and resetting parameters prior to
reinitialization.
- "zram: fix stale scan bounds after reinitialization" (Longlong Xia)
Prevent out-of-bounds slot accesses during concurrent zram resets by
moving table scan bound calculations under dev_lock in
writeback_store() and read_block_state().
- "add anon mTHP collapse test cases" (Baolin Wang)
Extend selftests helper functions to support arbitrary page orders
and add new test cases and options for mTHP collapse in khugepaged.
- "selftests/mm: Handle unsupported and transient test conditions"
(Muhammad Usama Anjum)
Update MM selftests to report a SKIP status instead of a failure when
required kernel or filesystem features are unsupported, while adding
retry logic for transient page migration errors.
- "mm/zswap: Fixes and improves the zswap shrink" (Hao Jia)
Fix the missing zswap global shrinker when CONFIG_MEMCG is disabled
and extend shrink_memcg() to support batch writeback for improved
writeback efficiency.
- "alloc_tag: introduce IOCTL-based filtering for MAP" (Suren
Baghdasaryan)
Introduce an IOCTL-based binary interface for memory allocation
profiling that enables kernel-side filtering before per-CPU counter
aggregation.
This eliminates the text-parsing overhead of /proc/allocinfo and
provides up to a 20x speedup by transferring only filtered allocation
data to userspace.
- "better block swap batching and a different take on swap_ops v5"
(Christoph Hellwig)
Refactor block swap I/O to use swap_iocb for batching instead of
single-bio requests and rebase the swap_ops interface, achieving
faster swap throughput during kernel builds.
- "mm: kmemleak: reduce transient false positives by confirming leaks"
(Catalin Marinas)
Reduce false-positive kmemleak reports by combining two kmemleak
enhancements that add a second confirmation scan and a configurable
minimum unreferenced scan count module parameter.
- "mm: kmemleak: default min_unref_scans to 2 for verbose kernels"
(Breno Leitao)
Auto-scanning kernels can generate false-positive memory leak reports
on single scans, so this patch defaults min_unref_scans to 2 when
CONFIG_DEBUG_KMEMLEAK_VERBOSE is enabled to require a second
confirming scan.
- "swap_ops updates" (Christoph Hellwig)
Batching I/O for synchronous swap devices causes performance
regressions and filesystem-based swap suffers from double-indirection
overhead. This series resolves both issues by reintroducing per-folio
writes for synchronous swap and allowing filesystems to directly
export their own swap_ops.
- "mm/khugepaged: several cleanups" (Nico Pache)
khugepaged accumulated redundant state-checking patterns and outdated
comments following mTHP integration. Introduce dedicated helpers for
PTE validation and event counting while refreshing the internal
documentation.
- "maple_tree: lock checking and clean ups" (Liam Howlett)
Syzbot reports incorrectly blame memory management exit paths for
locking bugs, maple tree erase operations risk allocation failures
without gfp flags and internal documentation lacks clarity.
Improve lock error detection, update docs, fix race and allocation
edge cases and optimize erase allocations using a fallback to
GFP_KERNEL | GFP_NOFAIL.

Moving the register definitions to a global header file
include/linux/designware_i2c.h. That removes the need to
duplicate them in the adaptation layers for this driver
outside of drivers/i2c/busses/. There is at least one of
those in drivers/gpu/drm/xe/xe_i2c.c.

ASoC: Fixes for v7.3
A fairly big batch of fixes that came in during the merge window.
There's a lot of quirks for x86 systems and a bunch of driver specific
fixes, the most critical being the fixes for Tegra's register
definitions. It turned out that they had been relying on the regmap
default handling bugs that were fixed in v7.2 and so audio was fairly
badly broken, unfortunately the issue wasn't noticed in time for
release.

Both the dynset and newsetelem path clone the existing set expressions
when setting set element expressions if no override expressions are
provided. This results in a double clone, once to clone the template set
expressions then another clone on the new element. Add a flag to
annotate if userspace provides a override expression (ie. expression of
the same type of the set but different configuration), otherwise borrow
the existing expression from the set. Add conditionals to release
expression iif they represent an override. Use this new override_exprs
flag to dump the dynset expression override to userspace.
This simplifies the existing logic and it also fixes a bug with the
connlimit expression which results in a module refcount imbalance
WARNING splat when resorting on the default set expressions.
Fixes: 65038428b2c6 ("netfilter: nf_tables: allow to specify stateful expression in set definition")

The user can specify any gso_size in a packet crafted with an AF_PACKET
PACKET_VNET_HDR socket, even smaller than TCP_MIN_GSO_SIZE = 8. At the
same time, GSO_MAX_SIZE = 8 * GSO_MAX_SEGS = 8 * 65535. When the user
crafts a packet with gso_size < 8, there is a risk for partial GSO to
overflow the 16-bit gso_segs field when dividing the SKB length by
gso_size.
Adjust gso_size of TCP packets to be at least TCP_MIN_GSO_SIZE = 8. Keep
gso_size of UDP GSO packets, as gso_size=1 is valid and explicitly
tested at tools/testing/selftests/net/tun.c:649.

Pull clk updates from Stephen Boyd:
"Mostly the usual clk driver updates and new SoC additions plus
non-critical data fixes for things that weren't used yet.
One thing that's new here in the core is SSC spread spectrum support
(SSC) in the clk provider API. The idea is that DT authors will
configure SSC for certain clks and they'll be configured at clk
provider registration time or when a consumer device is probed,
similar to how we handle assigned clk rates or parents.
On the clk driver side we have Qualcomm adding almost half the diff
because they add support for 4 different SoCs and then a long tail of
other SoCs like Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more
SoC support this time around. Luckily it's mostly clk data for these
new SoCs because the actual clk_ops are already there. Beyond the new
drivers we get all the little fixups for more compilation coverage or
usage of more modern APIs. That all looks normal.
Finally, I kinda buried the lede, I'm bringing on Brian and Jerome to
help out with maintaining the clk subsystem. The current working model
is already semi-distributed in that silicon vendors typically take
care of their drivers and send me pull requests but I'm becoming a
bottleneck for new drivers and core framework review because this has
become a 100% volunteer effort on my part.
Mike is stepping down after all these years (thanks Mike!) and that
jump started the conversation around finding co-maintainers. Brian and
Jerome have graciously offered to help me with the work load, meaning
in the future they'll be sending pull requests and committing directly
to the clk.git tree. They've both been around on the list for a while,
I've met them both in person, and they've been making changes to the
core clk framework along with helping review patches so I'm pretty
confident this will work well.
Core:
- devm_clk_bulk_get_enable() consumer API
- devm_clk_hw_register_composite_pdata() provider API
- Spread Spectrum Clock (SSC) support via DT bindings and provider APIs
- Divider clk rounding improved (and tested)

- Cix Sky1 audio subsystem (AUDSS)
- UltraRISC DP1000

ceph_put_page_vector() was paired with ceph_get_direct_page_vector(),
which was removed in commit 97a385e55829 ("libceph: remove
ceph_get_direct_page_vector()"). Its only remaining caller,
finish_netfs_read(), uses it to put a page vector allocated with
iov_iter_get_pages_alloc2(), which is confusing. Open-code the
put_page() loop and kvfree() there instead.
The caller passed dirty = false, so this also removes the dead dirty
branch and with it a call to the deprecated set_page_dirty_lock().

Pull another power sequencing update from Bartosz Golaszewski:
"A single tree-wide rename of two of the public functions to better
reflect their actual semantics:
- rename pwrseq_power_on/off() to pwrseq_enable/disable() tree-wide"
* tag 'pwrseq-updates-for-v7.3-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable()
|
|
The way power sequencing works means that a call to pwrseq_power_on()
does not necessarily result in the pwrseq target being powered-on at
that time: it may have already been powered on before. Similarly: a call
to pwrseq_power_off() does not have to result in an actual powering off
of resources: there may still be other users that requested a power-on
before.
We will also introduce the concept of "non-controllable" pwrseq targets
soon which further increases the disconnect between the naming
convention and the actual semantics.
What consumers of pwrseq descriptors actually do is: they *vote* for a
powering on of a given target or retract that vote. These operations
could be called get/put in line with runtime PM but this could become
confusing since we already provide pwrseq_get/put() for a different
purpose. pwrseq_vote_on/off() also have been rejected as unusual in
the tree.
Change the name of the two functions to pwrseq_enable/disable() which
better reflects their purpose and semantics and also mirrors other
enable-counted resources like regulators and clocks. No functional change
intended.
If at any point users need to know *when* the exact power event happens,
we can provide that information in the form of a notifier.

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Add support for 'slot' based PMU events, paired with new UAPI that
compels the user to select a specific PMU implementation
- Lazy save/restore of vCPU state for pKVM, along with various fixes
and cleanups to the management of vCPU state between the untrusted
host and pKVM hypervisor
- Disable traps of EL1 registers for nested hypervisors when
FEAT_NV2p1 is present, guaranteeing that EL2-specific register bits
are stateful in the EL1 counterpart
- Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the
scope of those instructions remains 'in host' (i.e. L1
kernel/userspace)
- Pile of fixes for the management of the VNCR pseudo-TLB, such as
under-invalidations and races with concurrent TLBIs on other vCPUs
- Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
runtime-patched constant, allowing the same data to be shared with
pKVM prior to dropping host privileges
- Considerable pile of LLM-assisted fixes around the shop but mostly
in the VGIC, our in-kernel generator of bugs (and sometimes
interrupts)
LoongArch:
- Advertise already-supported capabilities
- Some bug fixes about timer and MMIO
- Some hardening about interrupt injection
- Replace kvm_err() with kvm_pr_unimpl()
- Add FPU/LSX/LASX test cases for selftests
RISC-V:
- Svadu/Zicfiss/Zicfilp FWFT support for Guest
- Use try_cmpxchg for IMSIC MRIF RMW
- More arch-specific tracepoints in KVM RISC-V
- Eager page splitting when enabling dirty logging
- Optimize hfence request handling for SMP Guests
- Improve dirty log clearing by skipping zero bits in mask
- Guard HFENCE range loops against overflow
- CPU PM notifiers in KVM RISC-V for non-retentive idle states
- Fix kernel-mode vector context save/restore for Guest
s390:
- Fixes for vfio-ap
- Fixes for the gmap rework
- Fixes for vsie
- AI triggered fixes all over
- diag9c tracing
- code move preparation for the additional arm64 support
- enable CONTEXT_ANALYSIS
x86:
- Perform spring cleaning on x86.{c,h} and asm/kvm_host.h, by adding
regs.c (the kvm_cache_regs.h => regs.h is already applied) and
msrs.{c,h}, and moving relevant code out of x86.c
- Split kvm_mmu in three parts, respectively to describe the format
of page tables, walking the guest page tables and building the page
tables. Always use the same page table walker kvm->arch.gva_walk as
the entry point to convert a guest's virtual address, where the
previous code used two different kvm_mmu structs depending on
whether the walk included nested EPT/NPT or not. Make page fault
vmexits reuse the permission checking machinery that is used for
guest page faults. This is both a cleanup and a baby step towards
supporting XS/XU memory permissions
- Document some of the "fun" gotchas with the APIC base when creating
IRQCHIPs on x86
- Remove a defunct masterclock update from kvm_xen_shared_info_init().
It could result in incorrect kvmclock due to triggering an
unnecessary switch to/from masterclock mode
- Skip Xen runstate time updates if time has effectively gone
backwards, so that the guest doesn't report 100% steal time for
a very, very long time
- Drop KVM's runtime updates of the Xen PV timing CPUID leaf, as KVM
was updating the wrong sub-leaf, and upstream KVM will soon provide
all the information needed by userspace to populate the CPUID field
itself
- Fix a bug where KVM would walk a newly created rmap without holding
the rmap lock (or mmu_lock) during aging
- Fix a bug where aging TDP MMU SPTEs could clobber FROZEN SPTEs
- Fix a variety of #DB priority bugs
- Fix a class of races related to enabling Hyper-V emulation on a
vCPU after the vCPU is visible to the rest of KVM
- Use static calls for nested virtualization ops
- Move more KVM-internal code out of x86's kvm_host.h
- Enumerate support for a variety of Zhaoxin instructions that don't
require explicit virtualization
- Fix missing EFER validation bugs, including in the KVM_SET_SREGS*
path
- Harden kvm_vcpu_map() against double-mapping and thus leaking
references
- Misc fixes and cleanups, e.g. for largely benign syzkaller splats
x86 (Intel):
- Zero a vCPU's entry in VMX's Posted Interrupt Descriptor table used
for IPI virtualization when the vCPU is freed, to fix a
use-after-free where hardware will write to a freed vCPU's PID
- Service local TLB flushes on a failed nested VM-Enter to fix a bug
where KVM could miss a TLB on a future, successful VM-Enter with
the same L2 VPID
- Cap the maximum value shoved into the VMX Preemption Timer to
workaround an erratum that affects all existing Intel CPUs that
support CPUID 0x15
- Fix VPID virtualization bugs where KVM would fail to flush hardware
TLBs
- Harden the TDX "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion
x86 (AMD):
- Forcefully invalidate SNP VMSA pages if their backing guest_memfd
page is zapped/invalidated, e.g. due to a PUNCH_HOLE in response to
a Page-State Change request
- Remove a dying VM from the GA Log notifier list before the VM is
actually destroyed, to fix a potential use-after-free
- While FOLL_WRITE was needed in the past to trigger CoW unsharing,
nowadays FOLL_LONGTERM does that already even without FOLL_WRITE,
and in fact, get_user_pages() actually disallows FOLL_WRITE
together with FOLL_LONGTERM. So don't pass FOLL_WRITE when
registering encrypted memory regions, i.e. when pinning SEV/SEV-ES
guest memory, to fix a regression with file-backed memory
introduced by KVM's (correct) usage of long-term pins
(This was reviewed by mm maintainers; for more information, see
commit ee1a586dd1fa "KVM: SEV: Drop FOLL_WRITE for encrypted region
registration")
- Allocate full pages for SEV/SEV-ES {DE,EN}CRYPT ops on SNP-enabled
hosts to fix a data corruption issue due to the PSP driver
assigning to-be-written pages to firmware (as required by the SNP
specs)
- Unconditionally intercept ICBEP so that KVM generates the correct
guest RIP when handling an ICEBP-induced TASK_SWITCH #VMEXIT
- Harden the SNP "populate" ioctls against bad input, and to prepare
for supporting in-place private<=>shared conversion
Generic:
- Remove kvm_debugfs_dir if kvm_init() fails after creating KVM's
debugfs
- Add a per-VM bitmap to track which vCPU IDs have been "claimed" but
for which the vCPU isn't yet online, and use the bitmap to reject
duplicate IDs before calling into arch code. This allows arch code
to consume vcpu_id without having to worry about cross-vCPU
clobbering (at least s390 and x86 have had related bugs)
- Rework the so called "prepare" and "invalidate" guest_memfd hooks
to prepare for in-place private<=>shared conversion, and clean up a
few warts along the way
Selftests:
- Automatically allocate a full page for L2 guest stacks on x86
instead of requiring test-specific L1 guest code to carve out a
portion of the L1 stack for L2 usage, and to ensure the L2 stack
also adheres to the x86-64 calling convention ABI
- Add a selftest to verify {Guest,Host}-Only behavior in x86's
mediated PMU
- Clean up nested SVM's handling of GPRs on L2<=>L1 transitions,
reuse the functionality for nested VMX, and drop the ucall hack
that was fudging around the lack of GPR switching on nVMX
- Add a stress test to verify KVM doesn't clobber/drop #PF state,
e.g. CR2, across save/restore, including when L2 is active
- Add a test to verify KVM_CREATE_VM accepts exactly what is reported
by KVM_CAP_VM_TYPES
- Misc selftests fixes and cleanups
- Fix several issues with seeding the pRNG, and rework the pRNG APIs
to that the pRNG can be sanely used in host code, not just guest
code
- Add an IRQ test to validate virtual IRQ deliverty for IRQs wired up
via KVM_IRQFD + KVM_SET_GSI_ROUTING, with optional support for
triggering IRQs via writes to an assigned VFIO device
- Add syscall wrappers to assert success on a variety of pthreads and
CPU affinity APIs
- Set vCPU pthread affinity as early as possible to reduce contention
issues that were surfaced by PREEMPT_LAZY, which result in runtimes
of over a minute on large hosts, versus the expected ~5 seconds
- Rework the PMU counters test to run each testcase using a single VM
with many vCPUs for each sub-testcase, instead of using a unique VM
for each sub-testcase. This cuts the runtime by ~20x
Miscellaneous:
- MAINTAINERS updates for vfio-ap, guest_memfd, kvm-x86. Mostly
representing the status quo more accurately, but also... welcome

Decouple kzalloc from buffer creation, so that a managed allocation can be
used:
struct tpm_buf *buf __free(kfree) buf = kzalloc(TPM_BUFSIZE,
GFP_KERNEL);
if (!buf)
return -ENOMEM;
tpm_buf_init(buf, TPM_BUFSIZE);
Alternatively, other allocations are also possible (static data, stack,
etc) for example:
u8 buf_data[512];
struct tpm_buf *buf = (struct tpm_buf *)buf_data;
tpm_buf_init(buf, sizeof(buf_data));
This is achieved by embedding buffer's header inside the allocated blob,
instead of having an outer wrapper.

These are definitions for TPM 2.0 interface and interactions with
the platform as defined in the TCG specification:
These definitions are located here in a separate file to avoid conflicts
with vendor specific TIS/FIFO definition (e.g. STMicroelectronics,
Infineon Technologies, etc). This allows the TCG defined TIS/FIFO
interface to be in a public header while the former chip specific
implementations contain their own definitions. TPM 1.x family chips
that adhere to the TCG specifications use the TIS/FIFO interface as
defined here.

While we attempted to work around the false-positive lockdep warning
due to the nested mutex lock in rawmidi at the open path for a UMP
legacy rawmidi, it didn't cover the similar locking at its close path,
and this still caused another false-positive reports by syzkaller.
Add a similar workaround to snd_rawmidi_kernel_release() as done in
the former commit 9c04742e73b3 ("ALSA: rawmidi: Work around
false-positive mutex lockdep warning") to cover completely.

A cached RECONF chunk may contain more than one request parameter. A
duplicate response can therefore find and process the same ADD_OUT request
again while another parameter is still outstanding, rolling back outcnt
twice and possibly underflowing it.
Track outstanding request types as bits and clear each bit after its first
response. Later responses for the same request are then ignored.

Failures to remove entries using the two APIs to erase the entries may
result in allocation failures. The failures may go unnoticed and an
unexpected entry may remain. Instead, fall back to retrying with
GFP_KERNEL | __GFP_NOFAIL so that the entry will be removed.

Use the lockdep sequence numbers to ensure the write lock is not dropped
between write operations. The lockdep sequence is recorded on any walk
that starts from the top of the tree and re-checked prior to any operation
using an active node.
When lockdep detects an issue, it sets debug_locks to 0 disabling further
reports. __lock_sequnece() will return u32 ~0 when debug_locks is zero,
and the real sequnece count cannot return such a high value as it is less
than 32bits.
By always updating the sequence number, regardless of lock state and by
ignoring ~0 value in the sequence number will avoid ever printing a
WARN_ON when lockdep sets debug_locks to 0.

Add an 8 bit small sequence counter to the held_lock struct to detect if
the lock as been dropped and reacquired. This is useful when a data
structure depends on a constant locking context, but is not able to detect
locking and unlocking of the lock through its own API.
Since the __lock_unpin_lock() will no longer detect underflow by casting
the unsigned int to a signed int, update the casting code to use a temp
variable for calculations using a signed int.

Patch series "maple_tree: lock checking and clean ups", v3.
In this series:
1. Try to detect lock issues
A number of syzbot reports are incorrectly pointing to the mm exit as
a source of the locking error. The first three patches attempt to
help users detect errors in their locking - but they still have to use
LOCKDEP. I guess it's still down to hope and prayers.
2. Documentation fixes
The documentation was lacking clarity, there are updates to try and
help the users, especially around the erase() cases.
3. Two benign issues
The cyclic allocator may have a race, although no in-kernel user can
hit it.
The erase functions may cause allocation issues if used with the
incorrect locking type, but none are present in-tree.
4. The erase gfp uses
mas_erase() and mtree_erase() do not take a gfp argument. To improve
reliability of the erase, the first attempt to allocate will be
GFP_NOWAIT, followed by a retry (if necessary of GFP_KERNEL |
GFP_NOFAIL. This will ensure the data is gone. I've updated the
documentation to make it more clear as well. mas_store() is not
addressed in the same way, but may need to be updated at a later date,
but that may require changing callers so it is out of scope here.
Beyond these goals there are some test fixes, some general speed-up
patches targeting extra work and cycles, and dropping dead code.
This patch (of 19):
When CONFIG_LOCKDEP and CONFIG_RCU_STRICT_GRACE_PERIOD is enabled, check
for rcu locking issues by recording the grace period in the maple state
and checking the rcu window is still valid whenever the maple state is
reused with a state that is not MA_START or MA_PAUSED.
