b6cfddd26e cxl: Adjust offset calculation for poison injection
The HPA to DPA translation for poison injection assumes that the
base address starts from where the CXL region begins. When the
extended linear cache is active, the offset can be within the DRAM
region. Adjust the offset so that it correctly reflects the offset
within the CXL region.

7c3643f204 acpi,srat: Fix incorrect device handle check for Generic Initiator
The Generic Initiator Affinity Structure in SRAT table uses device
handle type field to indicate the device type. According to ACPI
specification, the device handle type value of 1 represents PCI device,
not 0.

   - Pick the correct translation regime when doing a PTW on the back of

   - Prevent userspace from injecting an event into a vcpu that isn't
     initialised yet

   - Move timer save/restore to the sysreg handling code, fixing EL2
     timer access in the process

   - Add FGT-based trapping of MDSCR_EL1 to reduce the overhead of debug

   - Fix trapping configuration when the host isn't GICv3

   - Improve the detection of HCR_EL2.E2H being RES1

   - Drop a spurious 'break' statement in the S1 PTW

   - Don't try to access SPE when owned by EL3

  Documentation updates:

   - Document the failure modes of event injection

   - Document that a GICv3 guest can be created on a GICv5 host with
     FEAT_GCIE_LEGACY

  Selftest improvements:

   - Add a selftest for the effective value of HCR_EL2.AMO

   - Address build warning in the timer selftest when building with
     clang

   - Teach irqfd selftests about non-x86 architectures

   - Add missing sysregs to the set_id_regs selftest

   - Fix vcpu allocation in the vgic_lpi_stress selftest

   - Correctly enable interrupts in the vgic_lpi_stress selftest

  x86:

   - Expand the KVM_PRE_FAULT_MEMORY selftest to add a regression test
     for the bug fixed by commit 3ccbf6f470 ("KVM: x86/mmu: Return
     -EAGAIN if userspace deletes/moves memslot during prefault")

   - Don't try to get PMU capabilities from perf when running a CPU with
     hybrid CPUs/PMUs, as perf will rightly WARN.

  guest_memfd:

   - Rework KVM_CAP_GUEST_MEMFD_MMAP (newly introduced in 6.18) into a
     more generic KVM_CAP_GUEST_MEMFD_FLAGS

   - Add a guest_memfd INIT_SHARED flag and require userspace to
     explicitly set said flag to initialize memory as SHARED,
     irrespective of MMAP.

     The behavior merged in 6.18 is that enabling mmap() implicitly
     initializes memory as SHARED, which would result in an ABI
     collision for x86 CoCo VMs as their memory is currently always
     initialized PRIVATE.

   - Allow mmap() on guest_memfd for x86 CoCo VMs, i.e. on VMs with

dbfdaeb381 tpm_crb: Add idle support for the Arm FF-A start method
According to the CRB over FF-A specification [1], a TPM that implements
the ABI must comply with the TCG PTP specification. This requires support
for the Idle and Ready states.

This patch implements CRB control area requests for goIdle and
cmdReady on FF-A based TPMs.

The FF-A message used to notify the TPM of CRB updates includes a
locality parameter, which provides a hint to the TPM about which
locality modified the CRB.  This patch adds a locality parameter
to __crb_go_idle() and __crb_cmd_ready() to support this.

 - Explicitly encode the XZR register if the value passed to

   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

a1e83d4c03 selftests/bpf: Fix redefinition of 'off' as different kind of symbol
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
032676ff82 ("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.

7c33e97a6e bpf: Do not disable preemption in bpf_test_run().
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.

ea0d55ae4b arm64: debug: always unmask interrupts in el0_softstp()
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.

e9ad390a48 arm64/sysreg: Fix GIC CDEOI instruction encoding
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.

Since commit 54f45a30c0 ("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.

4a9cb2eecc docs: rust: add section on imports formatting
`rustfmt`, by default, formats imports in a way that is prone to conflicts
while merging and rebasing, since in some cases it condenses several
items into the same line.

For instance, Linus mentioned [1] that the following case:

    use crate::{
        fmt,
        page::AsPageIter,
    };

is compressed by `rustfmt` into:

    use crate::{fmt, page::AsPageIter};

which is undesirable.

Similarly, `rustfmt` may put several items in the same line even if the
braces span already multiple lines, e.g.:

    use kernel::{
        acpi, c_str,
        device::{property, Core},
        of, platform,
    };

The options that control the formatting behavior around imports are
generally unstable, and `rustfmt` releases do not allow to use nightly
features, unlike the compiler and other Rust tooling [2].

For the moment, we can introduce a workaround to prevent `rustfmt`
from compressing the example above -- the "trailing empty comment":

    use crate::{
        fmt,
        page::AsPageIter, //
    };

which is reminiscent of the trailing comma behavior in other formatters.
We already used empty comments for formatting purposes in the past,
e.g. in commit b9b701fce4 ("rust: clarify the language unstable features
in use").

In addition, `rustfmt` actually reformats with a vertical layout (i.e. it
does not put two items in the same line) when seeing such a comment,
i.e. it doesn't just preserve the formatting, which is good in the sense
that we can use it to easily reformat some imports, since it matches
the style we generally want to have.

A Git merge driver would help (suggested by Gary and Wedson), though
maintainers would need to set it up, the diffs would still be larger
and the formatting rules for imports would remain hard to predict.

Thus document the style that we will follow in the coding guidelines
by introducing a new section and explain how the trailing empty comment
works there too.

We discussed the issue with upstream Rust in our usual Rust <-> Rust
for Linux meeting [3], and there have also been a few other discussions
in parallel in issues [4][5] and Zulip [6]. We will see what happens,
but upstream Rust has already created a subteam of `rustfmt` to try
to overcome the bandwidth issue [7], which is a good signal, and some
organization work has already started (e.g. tracking issues). We will
continue our discussions with them about it.

5a869d0177 nvme/tcp: handle tls partially sent records in write_space()
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.

f6fddc6df3 bpf: Fix memory leak in __lookup_instance error path
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.
