Pull arm64 fixes from Catalin Marinas:
- Explicitly encode the XZR register if the value passed to
write_sysreg_s() is 0.
The GIC CDEOI instruction is encoded as a system register write with
XZR as the source register. However, clang does not honour the "Z"
register constraint, leading to incorrect code generation
- Ensure the interrupts (DAIF.IF) are unmasked when completing
single-step of a suspended breakpoint before calling
exit_to_user_mode().
With pseudo-NMIs, interrupts are (additionally) masked at the PMR_EL1
register, handled by local_irq_*()

This fixes the following build error
CLNG-BPF [test_progs] verifier_global_ptr_args.bpf.o
progs/verifier_global_ptr_args.c:228:5: error: redefinition of 'off' as
different kind of symbol
228 | u32 off;
| ^
The symbol 'off' was previously defined in
tools/testing/selftests/bpf/tools/include/vmlinux.h, which includes an
enum i40e_ptp_gpio_pin_state from
drivers/net/ethernet/intel/i40e/i40e_ptp.c:
enum i40e_ptp_gpio_pin_state {
end = -2,
invalid = -1,
off = 0,
in_A = 1,
in_B = 2,
out_A = 3,
out_B = 4,
};
This enum is included when CONFIG_I40E is enabled. As of commit
032676ff8217 ("LoongArch: Update Loongson-3 default config file"),
CONFIG_I40E is set in the defconfig, which leads to the conflict.
Renaming the local variable avoids the redefinition and allows the
build to succeed.

The timer mode is initialized to NO_PREEMPT mode by default,
this disables preemption and force execution in atomic context
causing issue on PREEMPT_RT configurations when invoking
spin_lock_bh(), leading to the following warning:
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 6107, name: syz.0.17
preempt_count: 1, expected: 0
RCU nest depth: 1, expected: 1
Preemption disabled at:
[<ffffffff891fce58>] bpf_test_timer_enter+0xf8/0x140 net/bpf/test_run.c:42
Fix this, by removing NO_PREEMPT/NO_MIGRATE mode check.
Also, the test timer context no longer needs explicit calls to
migrate_disable()/migrate_enable() with rcu_read_lock()/rcu_read_unlock().
Use helpers rcu_read_lock_dont_migrate() and rcu_read_unlock_migrate()
instead.

We intend that EL0 exception handlers unmask all DAIF exceptions
before calling exit_to_user_mode().
When completing single-step of a suspended breakpoint, we do not call
local_daif_restore(DAIF_PROCCTX) before calling exit_to_user_mode(),
leaving all DAIF exceptions masked.
When pseudo-NMIs are not in use this is benign.
When pseudo-NMIs are in use, this is unsound. At this point interrupts
are masked by both DAIF.IF and PMR_EL1, and subsequent irq flag
manipulation may not work correctly. For example, a subsequent
local_irq_enable() within exit_to_user_mode_loop() will only unmask
interrupts via PMR_EL1 (leaving those masked via DAIF.IF), and
anything depending on interrupts being unmasked (e.g. delivery of
signals) will not work correctly.
This was detected by CONFIG_ARM64_DEBUG_PRIORITY_MASKING.
Move the call to `try_step_suspended_breakpoints()` outside of the check
so that interrupts can be unmasked even if we don't call the step handler.

The GIC CDEOI system instruction requires the Rt field to be set to 0b11111
otherwise the instruction behaviour becomes CONSTRAINED UNPREDICTABLE.
Currenly, its usage is encoded as a system register write, with a constant
0 value:
write_sysreg_s(0, GICV5_OP_GIC_CDEOI)
While compiling with GCC, the 0 constant value, through these asm
constraints and modifiers ('x' modifier and 'Z' constraint combo):
asm volatile(__msr_s(r, "%x0") : : "rZ" (__val));
forces the compiler to issue the XZR register for the MSR operation (ie
that corresponds to Rt == 0b11111) issuing the right instruction encoding.
Unfortunately LLVM does not yet understand that modifier/constraint
combo so it ends up issuing a different register from XZR for the MSR
source, which in turns means that it encodes the GIC CDEOI instruction
wrongly and the instruction behaviour becomes CONSTRAINED UNPREDICTABLE
that we must prevent.
Add a conditional to write_sysreg_s() macro that detects whether it
is passed a constant 0 value and issues an MSR write with XZR as source
register - explicitly doing what the asm modifier/constraint is meant to
achieve through constraints/modifiers, fixing the LLVM compilation issue.

Pull io_uring fixes from Jens Axboe:
- Revert of a change that went into an older kernel, and which has been
reported to cause a regression for some write workloads on LVM while
a snapshop is being created
- Fix a regression from this merge window, where some compilers (and/or
certain .config options) would cause an earlier evaluations of a
dereference which would then cause a NULL pointer dereference.
I was only able to reproduce this with OPTIMIZE_FOR_SIZE=y, but David
Howells hit it with just KASAN enabled. Depending on how things
inlined, this makes sense
- Fix for a missing lock around a mem region unregistration
- Fix for ring resizing with the same placement after resize

commit 337bf13aa9dda ("PCI/VGA: Replace vga_is_firmware_default() with a
screen info check") introduced an implicit dependency upon SCREEN_INFO by
removing the open coded implementation.
If a user didn't have CONFIG_SCREEN_INFO set, vga_is_firmware_default()
would now return false. SCREEN_INFO is only used on X86 so add a
conditional select for SCREEN_INFO to ensure that the VGA arbiter works as
intended.

Since commit 54f45a30c0d0 ("PCI/MSI: Add startup/shutdown for per
device domains") set callback irq_startup() and irq_shutdown() of
the struct pci_msi[x]_template, __irq_startup() will always invokes
irq_startup() callback instead of irq_enable() callback overridden
in vmd_init_dev_msi_info(). This will not start the IRQ correctly.
Also override irq_startup()/irq_shutdown() in vmd_init_dev_msi_info(),
so the irq_startup() can invoke the real logic.

With TLS enabled, records that are encrypted and appended to TLS TX
list can fail to see a retry if the underlying TCP socket is busy, for
example, hitting an EAGAIN from tcp_sendmsg_locked(). This is not known
to the NVMe TCP driver, as the TLS layer successfully generated a record.
Typically, the TLS write_space() callback would ensure such records are
retried, but in the NVMe TCP Host driver, write_space() invokes
nvme_tcp_write_space(). This causes a partially sent record in the TLS TX
list to timeout after not being retried.
This patch fixes the above by calling queue->write_space(), which calls
into the TLS layer to retry any pending records.

When __lookup_instance() allocates a func_instance structure but fails
to allocate the must_write_set array, it returns an error without freeing
the previously allocated func_instance. This causes a memory leak of 192
bytes (sizeof(struct func_instance)) each time this error path is triggered.
Fix by freeing 'result' on must_write_set allocation failure.

Michal reported and bisected an issue after recent adoption
of skb_attempt_defer_free() in UDP.
The issue here is that skb_release_head_state() is called twice per skb,
one time from skb_consume_udp(), then a second time from skb_defer_free_flush()
and napi_consume_skb().
As Sabrina suggested, remove skb_release_head_state() call from
skb_consume_udp().
Add a DEBUG_NET_WARN_ON_ONCE(skb_nfct(skb)) in skb_attempt_defer_free()
Many thanks to Michal, Sabrina, Paolo and Florian for their help.

If obj_exts allocation failed, slab->obj_exts is set to OBJEXTS_ALLOC_FAIL,
But we do not clear it when freeing the slab. Since OBJEXTS_ALLOC_FAIL and
MEMCG_DATA_OBJEXTS currently share the same bit position, during the
release of the associated folio, a VM_BUG_ON_FOLIO() check in
folio_memcg_kmem() is triggered because the OBJEXTS_ALLOC_FAIL flag was
not cleared, causing it to be interpreted as a kmem folio (non-slab)
with MEMCG_OBJEXTS_DATA flag set, which is invalid because
MEMCG_OBJEXTS_DATA is supposed to be set only on slabs.
Another problem that predates sharing the OBJEXTS_ALLOC_FAIL and
MEMCG_DATA_OBJEXTS bits is that on configurations with
is_check_pages_enabled(), the non-cleared bit in page->memcg_data will
trigger a free_page_is_bad() failure "page still charged to cgroup"
When freeing a slab, we clear slab->obj_exts if the obj_ext array has
been successfully allocated. So let's clear it also when the allocation
has failed.

Fixes: 7612833192d5 ("slab: Reuse first bit for OBJEXTS_ALLOC_FAIL")

When adding dependencies with drm_sched_job_add_dependency(), that
function consumes the fence reference both on success and failure, so in
the latter case the dma_fence_put() on the error path (xarray failed to
expand) is a double free.
Interestingly this bug appears to have been present ever since
commit ebd5f74255b9 ("drm/sched: Add dependency tracking"), since the code
back then looked like this:
drm_sched_job_add_implicit_dependencies():
...
for (i = 0; i < fence_count; i++) {
ret = drm_sched_job_add_dependency(job, fences[i]);
if (ret)
break;
}
for (; i < fence_count; i++)
dma_fence_put(fences[i]);
Which means for the failing 'i' the dma_fence_put was already a double
free. Possibly there were no users at that time, or the test cases were
insufficient to hit it.
The bug was then only noticed and fixed after
commit 9c2ba265352a ("drm/scheduler: use new iterator in drm_sched_job_add_implicit_dependencies v2")
landed, with its fixup of
commit 4eaf02d6076c ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies").
At that point it was a slightly different flavour of a double free, which
commit 963d0b356935 ("drm/scheduler: fix drm_sched_job_add_implicit_dependencies harder")
noticed and attempted to fix.
But it only moved the double free from happening inside the
drm_sched_job_add_dependency(), when releasing the reference not yet
obtained, to the caller, when releasing the reference already released by
the former in the failure case.
As such it is not easy to identify the right target for the fixes tag so
lets keep it simple and just continue the chain.
While fixing we also improve the comment and explain the reason for taking
the reference and not dropping it.

Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>:
This patch series addresses a set of issues in the Nuvoton NAU88L21
audio codec driver related to interrupt handling and jack hotplug
detection reliability.
The changes focus on:
* Eliminating race conditions between jack insertion and ejection events
* Ensuring interrupts are consistently and correctly cleared before
unmasking
* Introducing a DMI-based quirk to bypass the jack debounce circuit on
Valve Steam Deck, improving detection accuracy under stress
* Improving robustness of the IRQ handler by avoiding unnecessary
blocking operations
The series has been tested on affected hardware to verify correct
behavior during repeated and rapid jack hotplug cycles.

This assert can trigger here with non pin_map users that select
LATE_RESTORE, since the vmap is allowed to be NULL given that
save/restore can now use the blitter instead. The check here doesn't
seem to have much value anymore given that we no longer move pinned
memory, so any existing vmap is left well alone, and doesn't need to be
recreated upon restore, so just drop the assert here.
