Modules changes for 6.16-rc1
- Make .static_call_sites in modules read-only after init The .static_call_sites sections in modules have been made read-only after init to avoid any (non-)accidental modifications, similarly to how they are read-only after init in vmlinux. - The rest are minor cleanups. The changes have been on linux-next for 2 months, with the exception of the last comment-only cleanup. As discussed previously, we rotate module maintainership among its co-maintainers every 6 months. Daniel Gomez is next in line and he will send the next pull request for the modules. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEEIduBR9MnFA82q/jtumpXJwqY6poFAmg9tSoUHHBldHIucGF2 bHVAc3VzZS5jb20ACgkQumpXJwqY6poY/gf9GgexhRSNp10orTltOFD9+c+g6ekn q4UiLK7ooz4mFqPN4ljrSxvF1IYkjgrkkPDDEPZEZl2bQ7yWFb1xO9csihZeSI0l Bf5m+Pxo+U2ylNr6wEsOS7P5GntraTkLJ4NHje/bYmIQMAjiowniTF3693FYs51d bCD4Xn0zzZi+eekoAi/34GL5Zzkk5jhr2nBBvUZ3mXrRlR/iNpwUd4IWxb1Ujbfh 9YjAAGbeBowHzsyfPKoccJ/ybosrUKGqpVrp4KPe0JVoCvw8nwkxAfHGhsjjVk10 G0l4eCZ8KW87rPoJw5HvmTTNIxM10xKuZ4fa67/9ou+kHWRzMSa6ub4Jiw== =JU3a -----END PGP SIGNATURE----- Merge tag 'modules-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux Pull module updates from Petr Pavlu: - Make .static_call_sites in modules read-only after init The .static_call_sites sections in modules have been made read-only after init to avoid any (non-)accidental modifications, similarly to how they are read-only after init in vmlinux - The rest are minor cleanups * tag 'modules-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux: module: Remove outdated comment about text_size module: Make .static_call_sites read-only after init module: Add a separate function to mark sections as read-only after init module: Constify parameters of module_enforce_rwx_sections() |

Generic:
* Clean up locking of all vCPUs for a VM by using the *_nest_lock()
family of functions, and move duplicated code to virt/kvm/.
kernel/ patches acked by Peter Zijlstra.
* Add MGLRU support to the access tracking perf test.
ARM fixes:
* Make the irqbypass hooks resilient to changes in the GSI<->MSI
routing, avoiding behind stale vLPI mappings being left behind. The
fix is to resolve the VGIC IRQ using the host IRQ (which is stable)
and nuking the vLPI mapping upon a routing change.
* Close another VGIC race where vCPU creation races with VGIC
creation, leading to in-flight vCPUs entering the kernel w/o private
IRQs allocated.
* Fix a build issue triggered by the recently added workaround for
Ampere's AC04_CPU_23 erratum.
* Correctly sign-extend the VA when emulating a TLBI instruction
potentially targeting a VNCR mapping.
* Avoid dereferencing a NULL pointer in the VGIC debug code, which can
happen if the device doesn't have any mapping yet.
s390:
* Fix interaction between some filesystems and Secure Execution
* Some cleanups and refactorings, preparing for an upcoming big series
x86:
* Wait for target vCPU to acknowledge KVM_REQ_UPDATE_PROTECTED_GUEST_STATE to
fix a race between AP destroy and VMRUN.
* Decrypt and dump the VMSA in dump_vmcb() if debugging enabled for the VM.
* Refine and harden handling of spurious faults.
* Add support for ALLOWED_SEV_FEATURES.
* Add #VMGEXIT to the set of handlers special cased for CONFIG_RETPOLINE=y.
* Treat DEBUGCTL[5:2] as reserved to pave the way for virtualizing features
that utilize those bits.
* Don't account temporary allocations in sev_send_update_data().
* Add support for KVM_CAP_X86_BUS_LOCK_EXIT on SVM, via Bus Lock Threshold.
* Unify virtualization of IBRS on nested VM-Exit, and cross-vCPU IBPB, between
SVM and VMX.
* Advertise support to userspace for WRMSRNS and PREFETCHI.
* Rescan I/O APIC routes after handling EOI that needed to be intercepted due
to the old/previous routing, but not the new/current routing.
* Add a module param to control and enumerate support for device posted
interrupts.
* Fix a potential overflow with nested virt on Intel systems running 32-bit kernels.
* Flush shadow VMCSes on emergency reboot.
* Add support for SNP to the various SEV selftests.

A big core MTD change is the introduction of a new class to always
register a master device. This is a problem that has been there forever: the "master" device was not always present depending on a number of heuristics such as the presence of fixed partitions and the absence of a Kconfig symbol to force its presence. This was a problem for runtime PM operations which might not have the "master" device available in all situation. The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible. Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP table fixups for Macronix MX25L3255E have been merged. Aside from this, there is the usual load of misc improvement, fixes, and yaml conversion. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmg91NEACgkQJWrqGEe9 VoR8egf+JPTtykQ+Bip9bHStgfpxi0+OKL81PUuPBsbs5C546u5t6ZRhoPsU+KqL ZTyUk3ys7HcSwZCuiS9V6ea6TNV1FvAVZm+ONpkuPnU60++z8YfVr8ZvtgT0IUXx COi+5ksdsTFZMyRG+VybRKnYNrTYB7j7CqVL8ifxq1XYWnYdhjy5PH4DgAKnBhGL 523kN2eR85AhvJ4aulsKbcqQQYKvJIQbhjAKklA3yQVarDmoOdiSmndoZlRy+MDu B9DaRMvRRa/g1nI0stvR9K7FtdSrMYTg4kowR9jPRx0zEZXFFsZbASgcC+3G7HdK 7rLFWrN+G6fitcEjeAnfyV+sKF48LA== =tW1t -----END PGP SIGNATURE----- Merge tag 'mtd/for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull MTD updates from Miquel Raynal: "A big core MTD change is the introduction of a new class to always register a master device.

The SPI NAND subsystem has seen the introduction of DTR operations (the
equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible. Aside from this, there is the usual load of misc improvement and fixes. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmg90ysACgkQJWrqGEe9 VoTK8gf/U+28sdthNVHENmeQwgzMdjAaZkEn0qftRVplPUTGSqvkrTBQ2tsyGVpj V2jJ85WzQ6c+YVRjUsgojX4JClh0tfNrm8ySSu3TOAv98E/sCFttQgyCbELtt6GL P4/1g/BqHlagi1ouU95AtH3njZX9qXBq9cQGz3ZWX+qeS0p52wPsj1G8iy6syBR+ M6GZI92iINSXJUBlFBXzijDSxqcLWsAg8P2E5dTyL9Ukjcju0+fSQtt1oCp1F50+ zXJHfj3mB+BtBnX6nGhMu3sqY7LaM2NpEq7k6xtvo9ivWZwFAOK+uc31iGvAcKaZ R1A72QkRE3e0vQZjrX1JKZvXMVXt4Q== =Uj/O -----END PGP SIGNATURE----- Merge tag 'nand/for-6.16' into mtd/next The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names.

KVM/arm64 fixes for 6.16, take #1
- Make the irqbypass hooks resilient to changes in the GSI<->MSI routing, avoiding behind stale vLPI mappings being left behind. The fix is to resolve the VGIC IRQ using the host IRQ (which is stable) and nuking the vLPI mapping upon a routing change. - Close another VGIC race where vCPU creation races with VGIC creation, leading to in-flight vCPUs entering the kernel w/o private IRQs allocated. - Fix a build issue triggered by the recently added workaround for Ampere's AC04_CPU_23 erratum. - Correctly sign-extend the VA when emulating a TLBI instruction potentially targeting a VNCR mapping. - Avoid dereferencing a NULL pointer in the VGIC debug code, which can happen if the device doesn't have any mapping yet. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEn9UcU+C1Yxj9lZw9I9DQutE9ekMFAmg5fbgACgkQI9DQutE9 ekNMyhAAq99rswsyqUrDwTd4qwJBtRYj4FMkBD8rH1oPQcXkqPGVllOMOgAnJhtd mU1/XpU8gk49nsx5kwdg1RORQG4lKCZATH1F2MhInDWMMSSWUTWBu0+qG62GFQWF Db+aXcvyebHdfzunDmT1/NebhV9VGCnkUtbQrFBvBbqOt1xNCRhKNvv5RWNEugTW R2DIg4gCk2x1/iZceP8dDRDpnvFk8txtzZsWE6g1DZRw1mmlrz01rRgD7EJtkyaQ c74mqpc/A2GuJv2mwpz3GCXTLiNgAuNq1X9+yeEqYM+VVvuyGy906BTFXxgvYl6l o4OvE1F6QOtcJIokPb5kBlpxz76J2bNxKuUrY7rxM73Of0ZgGMsSltQxdcoGhJZ7 cyfUWFVQ+H5Gx+BVs/+5u2XdtX7OC0U50eXP0XrzviunTkEUhvRaH1WfTh9Zike/ U150d0oU17MeVZ9HlOWyhXV/nId6CPX5xo7BUjIq2e1Oy4mYkIYYbowdrV5t6NiJ FHwzXNa/T0prZDSPW4t1GL/8o8hcnd4KRGLTJDWBYk58J6S1hHG0QElAz5RvqUj+ nf8HSycZMBrpdXtIK6nu/GRk9Ng+6gT4KHomwjgIDj6QVn7DTFFId911j+HRmoCP DiV4QD4yVRSMBDX5cdQj2XBk2raMTOxdN9A1y6T2H3b+iLavVyo= =JjTn -----END PGP SIGNATURE----- Merge tag 'kvmarm-fixes-6.16-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 fixes for 6.16, take #1 - Make the irqbypass hooks resilient to changes in the GSI<->MSI routing, avoiding behind stale vLPI mappings being left behind.

overflow: Introduce __DEFINE_FLEX for having no initializer
While not yet in the tree, there is a proposed patch[1] that was
depending on the prior behavior of _DEFINE_FLEX, which did not have an
explicit initializer. Provide this via __DEFINE_FLEX now, which can also
have attributes applied (e.g. __uninitialized).
Examples of the resulting initializer behaviors can be seen here:

watchdog: iTCO_wdt: Update the heartbeat value after clamping timeout
When executing "modprobe iTCO_wdt heartbeat=700", the user-specified 'heartbeat' parameter exceeds the valid range, the driver clamps the timeout to default 30s but fails to update the logged 'heartbeat' value, resulting in misleading log output: iTCO_wdt iTCO_wdt: timeout value out of range, using 30 iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0) After validating the range, update the 'heartbeat' value with the clamped timeout value to ensure that log messages accurately reflect the actual runtime parameters.

watchdog: Add driver for Intel OC WDT
Add a driver for the Intel Over-Clocking Watchdog found in Intel Platform Controller (PCH) chipsets.

watchdog: arm_smc_wdt: get wdt status through SMCWD_GET_TIMELEFT
The optional SMCWD_GET_TIMELEFT command can be used to detect if the watchdog has already been started. See the implementation in OP-TEE secure OS [1]. At probe time, check if the watchdog is already started and then set WDOG_HW_RUNNING in the watchdog status. This will cause the watchdog framework to ping the watchdog until a userspace watchdog daemon takes over the control.

watchdog: apple: set max_hw_heartbeat_ms instead of max_timeout
The hardware only supports timeouts slightly below 3mins, but by using max_hw_heartbeat_ms we can let the kernel take care of supporting larger timeouts than that requested from userspace. Switching to max_hw_heartbeat_ms also means our set_timeout function now needs to configure the hardware to the minimum of either the requested timeout (in seconds) or the maximum supported by the user (in seconds).

selftests/mm: add helper for logging test start and results
Several of the MM tests have a pattern of printing a description of the test to be run then reporting the actual TAP result using a generic string not connected to the specific test, often in a shared function used by many tests. The name reported typically varies depending on the specific result rather than the test too. This causes problems for tooling that works with test results, the names reported with the results are used to deduplicate tests and track them between runs so both duplicated names and changing names cause trouble for things like UIs and automated bisection. As a first step towards matching these tests better with the expectations of kselftest provide helpers which record the test name as part of the initial print and then use that as part of reporting a result. This is not added as a generic kselftest helper partly because the use of a variable to store the test name doesn't fit well with the header only implementation of kselftest.h and partly because it's not really an intended pattern. Ideally at some point the mm tests that use it will be updated to not need it.

selftests/mm: use standard ksft_finished() in cow and gup_longterm
Patch series "selftests/mm: cow and gup_longterm cleanups", v2. The bulk of these changes modify the cow and gup_longterm tests to report unique and stable names for each test, bringing them into line with the expectations of tooling that works with kselftest. The string reported as a test result is used by tooling to both deduplicate tests and track tests between test runs, using the same string for multiple tests or changing the string depending on test result causes problems for user interfaces and automation such as bisection. It was suggested that converting to use kselftest_harness.h would be a good way of addressing this, however that really wants the set of tests to run to be known at compile time but both test programs dynamically enumarate the set of huge page sizes the system supports and test each. Refactoring to handle this would be even more invasive than these changes which are large but straightforward and repetitive. A version of the main gup_longterm cleanup was previously sent separately, this version factors out the helpers for logging the start of the test since the cow test looks very similar. This patch (of 4): The cow and gup_longterm test programs open code something that looks a lot like the standard ksft_finished() helper to summarise the test results and provide an exit code, convert to use ksft_finished().

sched/numa: add statistics of numa balance task
On systems with NUMA balancing enabled, it has been found that tracking
task activities resulting from NUMA balancing is beneficial. NUMA
balancing employs two mechanisms for task migration: one is to migrate
a task to an idle CPU within its preferred node, and the other is to
swap tasks located on different nodes when they are on each other's
preferred nodes.
The kernel already provides NUMA page migration statistics in
/sys/fs/cgroup/mytest/memory.stat and /proc/{PID}/sched. However, it
lacks statistics regarding task migration and swapping. Therefore,
relevant counts for task migration and swapping should be added.
The following two new fields:
numa_task_migrated
numa_task_swapped
will be shown in /sys/fs/cgroup/{GROUP}/memory.stat, /proc/{PID}/sched
and /proc/vmstat.
Introducing both per-task and per-memory cgroup (memcg) NUMA balancing
statistics facilitates a rapid evaluation of the performance and
resource utilization of the target workload. For instance, users can
first identify the container with high NUMA balancing activity and then
further pinpoint a specific task within that group, and subsequently
adjust the memory policy for that task. In short, although it is
possible to iterate through /proc/$pid/sched to locate the problematic
task, the introduction of aggregated NUMA balancing activity for tasks
within each memcg can assist users in identifying the task more
efficiently through a divide-and-conquer approach.
As Libo Chen pointed out, the memcg event relies on the text names in
vmstat_text, and /proc/vmstat generates corresponding items based on
vmstat_text. Thus, the relevant task migration and swapping events
introduced in vmstat_text also need to be populated by
count_vm_numa_event(), otherwise these values are zero in /proc/vmstat.
In theory, task migration and swap events are part of the scheduler's
activities. The reason for exposing them through the
memory.stat/vmstat interface is that we already have NUMA balancing
statistics in memory.stat/vmstat, and these events are closely related
to each other. Following Shakeel's suggestion, we describe the
end-to-end flow/story of all these events occurring on a timeline for
future reference:
The goal of NUMA balancing is to co-locate a task and its memory pages
on the same NUMA node. There are two strategies: migrate the pages to
the task's node, or migrate the task to the node where its pages
reside.
Suppose a task p1 is running on Node 0, but its pages are located on
Node 1. NUMA page fault statistics for p1 reveal its "page footprint"
across nodes. If NUMA balancing detects that most of p1's pages are on
Node 1:
1.Page Migration Attempt:
The Numa balance first tries to migrate p1's pages to Node 0.
The numa_page_migrate counter increments.
2.Task Migration Strategies:
After the page migration finishes, Numa balance checks every
1 second to see if p1 can be migrated to Node 1.
Case 2.1: Idle CPU Available
If Node 1 has an idle CPU, p1 is directly scheduled there. This
event is logged as numa_task_migrated.
Case 2.2: No Idle CPU (Task Swap)
If all CPUs on Node1 are busy, direct migration could cause CPU
contention or load imbalance. Instead: The Numa balance selects a
candidate task p2 on Node 1 that prefers Node 0 (e.g., due to its own
page footprint). p1 and p2 are swapped. This cross-node swap is
recorded as numa_task_swapped.

sched/numa: fix task swap by skipping kernel threads
Patch series "sched/numa: add statistics of numa balance task migration",
v6.
Introduce task migration and swap statistics in the following places:
/sys/fs/cgroup/{GROUP}/memory.stat
/proc/{PID}/sched
/proc/vmstat
These statistics facilitate a rapid evaluation of the performance and
resource utilization of the target workload.
This patch (of 2):
Task swapping is triggered when there are no idle CPUs in task A's
preferred node. In this case, the NUMA load balancer chooses a task B
on A's preferred node and swaps B with A. This helps improve NUMA
locality without introducing load imbalance between nodes. In the
current implementation, B's NUMA node preference is not mandatory.
That is to say, a kernel thread might be incorrectly chosen as B.
However, kernel thread and user space thread that does not have mm are
not supposed to be covered by NUMA balancing because NUMA balancing
only considers user pages via VMAs.
According to Peter's suggestion for fixing this issue, we use
PF_KTHREAD to skip the kernel thread. curr->mm is also checked because
it is possible that user_mode_thread() might create a user thread
without an mm. As per Prateek's analysis, after adding the PF_KTHREAD
check, there is no need to further check the PF_IDLE flag:
: - play_idle_precise() already ensures PF_KTHREAD is set before adding
: PF_IDLE
:
: - cpu_startup_entry() is only called from the startup thread which
: should be marked with PF_KTHREAD (based on my understanding looking at
