Add a dedicated local APIC API, kvm_x2apic_disable_intercept_reg_mask(),
to provide the mask of x2APIC registers whose MSRs can and should be passed
through to the guest when x2APIC virtualization is enable, and use it in
lieu of the open-coded equivalent VMX logic. Providing a common helper
will allow sharing the logic with SVM (x2AVIC), and as a bonus eliminates
the somewhat confusing code where KVM enables interception for MSR_TYPE_RW,
even though only the READ case actually needs to be updated.
No functional change intended.

In test_mutliproc(), when send() or recv() returns an error (e.g.,
-1), the test continues to execute the remaining code and fails
repeatedly due to using EXPECT_GE.
For example, if a TLS connection is broken and recv() returns -1,
EXPECT_GE(res, 0) records a failure but does not stop the test.
The test then proceeds with left -= res (where res = -1), causing
left to increase unexpectedly, and the loop continues indefinitely.
This results in a massive number of identical failure messages:
# tls.c:1686:mutliproc_sendpage_writers:Expected res (-1) >= 0 (0)
# tls.c:1686:mutliproc_sendpage_writers:Expected res (-1) >= 0 (0)
... (hundreds of identical failures)
Fix this by replacing EXPECT_GE with ASSERT_GE. When send() or recv()
fails, ASSERT_GE immediately aborts the current test, preventing
the subsequent undefined behavior and endless failure messages.

Since some time the metric-only output columns are messed up and do not
line up with the header, which makes it hard to read. I haven't bisected
it, but presumably it was broken for some time.
There were multiple problems:
- The dummy pm invocation at the beginning did print a bogus field
- The column computation in pm did not agree with the header length
- The color escape strings from highlighting confuse printf's field
length computation
Fix all those. I simplified the column width computation significantly,
ignoring EVNAME_LEN, MGROUP_LEN, config->unit_width which don't
seem to be useful in the metric only context. It now only uses
the actual unit width as well as config->metric_only_len. The result
is more code removed than added.

- Fix for an issue with IORING_OP_NOP and using injection results
- Fix for an issue in IORING_OP_WAITID, where the info state was

cases it is not. Just clear the data upfront, so that non-initialized

- Fix for a lockdep reported issue, where IORING_OP_BIND enters file
create and hence hits mnt_want_write(), which creates a three part
lockdep cycle between the super lock, io_uring's uring_lock, and the
cred mutex
- Fix a regression introduced in this cycle with how linked timeouts
are deleted

covers all the cases

vsock_poll() reads vsk->peer_shutdown before taking the socket lock
to set EPOLLHUP and EPOLLRDHUP, then reads it again after taking
the lock to report EOF readability. A shutdown packet can update
peer_shutdown while poll is waiting for the lock, so one poll invocation
can report EOF readability without the corresponding HUP/RDHUP bits.
For connectible sockets, take one peer_shutdown snapshot after
lock_sock() and use it for all peer-shutdown-derived poll bits. For
datagram sockets, which do not take lock_sock() in poll(), take one
lockless READ_ONCE() snapshot and pair it with WRITE_ONCE() on the
writer side.
This keeps the peer-shutdown-derived bits internally consistent for each
poll pass.

====================
net: convert atm/xdp/af_iucv/l2tp_ppp/rxrpc/tipc to getsockopt_iter
This series continues the conversion of the remaining proto_ops getsockopt
callbacks to the new getsockopt_iter callback introduced in commit 67fab22a7a
("net: add getsockopt_iter callback to proto_ops").
The new callback takes a sockopt_t — a type-safe wrapper around iov_iter
plus an optlen field — instead of raw __user pointers. This:
- Replaces (char __user *optval, int __user *optlen) with sockopt_t *opt
- Reads the input buffer size from opt->optlen instead of get_user()
- Writes the option value via copy_to_iter() instead of copy_to_user()
- Reports the returned length via opt->optlen instead of put_user(),
independently of the bytes copied through the iter
Each conversion is a behaviour-preserving and code-style-preserving refactor;
no big changes being introduced, even when the code looks weird.

Convert TIPC sockets (msg, packet, stream proto_ops) to use the new
getsockopt_iter callback with sockopt_t.
Key changes:
- Replace (char __user *optval, int __user *optlen) with sockopt_t *sopt
- Use sopt->optlen for buffer length (input) and returned size (output)
- Use copy_to_iter() instead of put_user()/copy_to_user()
The sockopt_t parameter is named sopt to avoid collision with the
existing optname parameter named opt.
Note: Dropped the unnecessary parentheses to make checkpatch happier.
Also dropped two now-stale comments that referred to the old "res"
variable handling.

Add debugfs entries to expose hardware configuration and diagnostic
information that aids in debugging driver initialization and runtime
operations without adding noise to dmesg.
The debugfs directory for each PCI device is named using pci_name()
(the unique BDF address), and its creation and removal is integrated
into mana_gd_setup() and mana_gd_cleanup_device() respectively, so
that all callers (probe, remove, suspend, resume, shutdown) share a
single code path.

- gdma_protocol_ver, pf_cap_flags1: VF version negotiation results

When build_skb() fails in tun_xdp_one(), the function sets ret to
-ENOMEM and jumps to the out label, which returns without freeing the
page that vhost_net_build_xdp() allocated for the frame. As with the
short-frame rejection path, tun_sendmsg() discards the per-buffer error
and still returns total_len, so vhost_tx_batch() takes the success path
and never frees the page. Each build_skb() failure in a batch leaks one
page-frag chunk.

other error exits of tun_xdp_one() already perform.

Commit 150061a206 ("net/sched: fq_codel: local packets no longer count against memory limit")
made fq_codel not account for local packets in the
memory limit. Since tests a4bb, a4be, a4bf, a4c0, a4c1 were relying on
these packets being accounted so that parent's qlen notify callback was
executed, they broke.
Fix the tests by adding the qdiscs to ifb instead and making it see
mirred packets that came from scapy. That way the packets are accounted
in the memory limit and the parent's qlen notify callback is still
executed.

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.
This workqueue has no benefits being per-CPU, so make it unbound adding
WQ_UNBOUND, removing also the WQ_POWER_EFFICIENT flag.

cs_dbs_update() performs explicit checks against policy->min/max
before updating the target frequency. These checks are redundant as
__cpufreq_driver_target() already clamps the requested frequency to
the valid policy limits.
Remove the unnecessary boundary checks and simplify the update logic.
This also fixes an issue introduced by commit 00bfe05889 ("cpufreq:
conservative: Decrease frequency faster for deferred updates"), where
stale target comparisons could cause frequency updates to be skipped
entirely after deferred adjustments.

Drivers setting CPUFREQ_NEED_UPDATE_LIMITS expect target() to be
invoked even if the target frequency remains unchanged, so they can
update their internal policy limits state.
Currently the core invokes target() unconditionally whenever the
requested frequency matches policy->cur for such drivers, even if
policy->min and policy->max haven't changed since the previous update.
Track pending policy limit updates explicitly and skip redundant
target() invocations when neither the target frequency nor the

may not be enabled in the test root cgroup's subtree_control.
In that case, the child cgroup is created without the memory control

accounting checks.

This patch provides basic support for the K230 clock, which covers
all clocks in K230 SoC.
The clock tree of the K230 SoC consists of a 24MHZ external crystal
oscillator, PLLs and an external pulse input for timerX, and their
derived clocks.

Coccinelle (scripts/coccinelle/api/string_choices.cocci) flags an
opportunity to replace the open-coded ternary expression in the probe
dev_info() call:
k3-ringacc.c:1439:3-32: opportunity for
str_enabled_disabled(ringacc->dma_ring_reset_quirk)
Replace the ternary with str_enabled_disabled() and add the required
include for <linux/string_choices.h>.

pktdma_get_regs() returns a void __iomem * but uses ERR_PTR() on the
error path, causing sparse to warn about an address space mismatch.
Replace ERR_PTR() with IOMEM_ERR_PTR() to resolve the warning cleanly.

smatch warns:
knav_dma.c:390 of_channel_match_helper() warn: unsigned
'args.args[0]' is never less than zero.
of_phandle_args.args[] is uint32_t, so the 'args.args[0] < 0' check
is always false. of_parse_phandle_with_fixed_args() already handles
errors by returning a non-zero code, which is checked immediately
above. Remove the dead check.

DMA_PRIO_MASK (GENMASK(3, 0)) is defined alongside the other priority
macros but is never referenced in the code. tx_priority and rx_priority
are only ever assigned DMA_PRIO_DEFAULT (0) and are never sourced from
device tree or user-controlled input, so no out-of-range value is
possible. W=2 builds report:
knav_dma.c:32:9: warning: macro is not used [-Wunused-macros]
32 | #define DMA_PRIO_MASK GENMASK(3, 0)
Remove the dead macro.

Fix several address-space and type annotation issues reported by sparse:
- Change pdsp->command from 'void __iomem *' to 'u32 __iomem *' to
match the other union members (acc_command, qos_command); adjust
the offset in knav_queue_load_pdsp() from +0x18 to +0x6 to
preserve the 24-byte offset.
- Fix knav_queue_pdsp_wait() declaration: correct the parameter
annotation from 'u32 * __iomem' (pointer-in-iomem-space) to
'u32 __iomem *' (pointer-to-iomem); use 'unsigned int' for the
timeout parameter instead of bare 'unsigned'; fix the continuation-
line alignment.
- Use IOMEM_ERR_PTR() in knav_queue_map_reg() instead of ERR_PTR()
when returning an error as void __iomem *.
- Annotate the firmware data array as 'const __be32 *' instead of
'u32 *', as be32_to_cpu() requires __be32 input.

knav_dev_lock_held() is a single-use wrapper around
lockdep_is_held(&knav_dev_lock), used only as the lockdep condition
in for_each_handle_rcu. When CONFIG_PROVE_RCU_LIST is disabled,
list_for_each_entry_rcu() elides the condition argument entirely,
causing clang to report the macro as unused with W=2:
knav_qmss_queue.c:30:9: warning: macro is not used [-Wunused-macros]
30 | #define knav_dev_lock_held() \
Remove the intermediate macro and open-code lockdep_is_held() directly
in the for_each_handle_rcu definition.
