LG LD070WX3-SL01 was mistakenly documented as a simple DSI panel, which it clearly is not. Address this by adding the proper schema for this panel. There is only one user of this panel binding in the mainline Linux kernel, which is the Nvidia tablet Tegra Note 7. Its panel is broken anyway since it cannot initialize properly if the bootloader does not leave a pre-initialized panel. It also cannot suspend or re-initialize properly, since no DSI configuration is set and it has a loose regulator which relies on an always-on property rather than being hooked to the panel where it belongs. Tegra Note 7 device tree is adjusted as a part of this series.

2025-11-19arm64, tlbflush: don't TLBI broadcast if page reused in write faultHuang Ying
A multi-thread customer workload with large memory footprint uses fork()/exec() to run some external programs every tens seconds. When running the workload on an arm64 server machine, it's observed that quite some CPU cycles are spent in the TLB flushing functions. While running the workload on the x86_64 server machine, it's not. This causes the performance on arm64 to be much worse than that on x86_64. During the workload running, after fork()/exec() write-protects all pages in the parent process, memory writing in the parent process will cause a write protection fault. Then the page fault handler will make the PTE/PDE writable if the page can be reused, which is almost always true in the workload. On arm64, to avoid the write protection fault on other CPUs, the page fault handler flushes the TLB globally with TLBI broadcast after changing the PTE/PDE. However, this isn't always necessary. Firstly, it's safe to leave some stale read-only TLB entries as long as they will be flushed finally. Secondly, it's quite possible that the original read-only PTE/PDEs aren't cached in remote TLB at all if the memory footprint is large. In fact, on x86_64, the page fault handler doesn't flush the remote TLB in this situation, which benefits the performance a lot. To improve the performance on arm64, make the write protection fault handler flush the TLB locally instead of globally via TLBI broadcast after making the PTE/PDE writable. If there are stale read-only TLB entries in the remote CPUs, the page fault handler on these CPUs will regard the page fault as spurious and flush the stale TLB entries. To test the patchset, make the usemem.c from vm-scalability (https://git.kernel.org/pub/scm/linux/kernel/git/wfg/vm-scalability.git). support calling fork()/exec() periodically. To mimic the behavior of the customer workload, run usemem with 4 threads, access 100GB memory, and call fork()/exec() every 40 seconds. Test results show that with the patchset the score of usemem improves ~40.6%. The cycles% of TLB flush functions reduces from ~50.5% to ~0.3% in perf profile.

2025-11-19mm: add spurious fault fixing support for huge pmdHuang Ying
The page faults may be spurious because of the racy access to the page table. For example, a non-populated virtual page is accessed on 2 CPUs simultaneously, thus the page faults are triggered on both CPUs. However, it's possible that one CPU (say CPU A) cannot find the reason for the page fault if the other CPU (say CPU B) has changed the page table before the PTE is checked on CPU A. Most of the time, the spurious page faults can be ignored safely. However, if the page fault is for the write access, it's possible that a stale read-only TLB entry exists in the local CPU and needs to be flushed on some architectures. This is called the spurious page fault fixing. In the current kernel, there is spurious fault fixing support for pte, but not for huge pmd because no architectures need it. But in the next patch in the series, we will change the write protection fault handling logic on arm64, so that some stale huge pmd entries may remain in the TLB. These entries need to be flushed via the huge pmd spurious fault fixing mechanism.

ops_execute() calculates the size of a fence array based on XE_MAX_GT_PER_TILE, while the code that actually fills in the fence array uses a for_each_tlb_inval() iterator. This works out okay today since both approaches come up with the same number of invalidation fences (2: primary GT invalidation + media GT invalidation), but could be problematic in the future if there isn't a 1:1 relationship between TLBs needing invalidation and potential GTs on the tile. Adjust the allocation code to use the same for_each_tlb_inval() counting logic as the code that fills the array to future-proof the code.

2025-11-19printk: Avoid scheduling irq_work on suspendJohn Ogness
Allowing irq_work to be scheduled while trying to suspend has shown to cause problems as some architectures interpret the pending interrupts as a reason to not suspend. This became a problem for printk() with the introduction of NBCON consoles. With every printk() call, NBCON console printing kthreads are woken by queueing irq_work. This means that irq_work continues to be queued due to printk() calls late in the suspend procedure. Avoid this problem by preventing printk() from queueing irq_work once console suspending has begun. This applies to triggering NBCON and legacy deferred printing as well as klogd waiters. Since triggering of NBCON threaded printing relies on irq_work, the pr_flush() within console_suspend_all() is used to perform the final flushing before suspending consoles and blocking irq_work queueing. NBCON consoles that are not suspended (due to the usage of the "no_console_suspend" boot argument) transition to atomic flushing. Introduce a new global variable @console_irqwork_blocked to flag when irq_work queueing is to be avoided. The flag is used by printk_get_console_flush_type() to avoid allowing deferred printing and switch NBCON consoles to atomic flushing. It is also used by vprintk_emit() to avoid klogd waking. Add WARN_ON_ONCE(console_irqwork_blocked) to the irq_work queuing functions to catch any code that attempts to queue printk irq_work during the suspending/resuming procedure.

2025-11-19printk: Allow printk_trigger_flush() to flush all typesJohn Ogness
Currently printk_trigger_flush() only triggers legacy offloaded flushing, even if that may not be the appropriate method to flush for currently registered consoles. (The function predates the NBCON consoles.) Since commit 6690d6b52726 ("printk: Add helper for flush type logic") there is printk_get_console_flush_type(), which also considers NBCON consoles and reports all the methods of flushing appropriate based on the system state and consoles available. Update printk_trigger_flush() to use printk_get_console_flush_type() to appropriately flush registered consoles.

2025-11-19zloop: fix zone append check in zloop_rw()Damien Le Moal
While commit cf28f6f923cb ("zloop: fail zone append operations that are targeting full zones") added a check in zloop_rw() that a zone append is not issued to a full zone, commit e3a96ca90462 ("zloop: simplify checks for writes to sequential zones") inadvertently removed the check to verify that there is enough unwritten space in a zone for an incoming zone append opration. Re-add this check in zloop_rw() to make sure we do not write beyond the end of a zone. Of note is that this same check is already present in the function zloop_set_zone_append_sector() when ordered zone append is in use.

2025-11-19ima: Access decompressed kernel module to verify appended signatureCoiby Xu
Currently, when in-kernel module decompression (CONFIG_MODULE_DECOMPRESS) is enabled, IMA has no way to verify the appended module signature as it can't decompress the module. Define a new kernel_read_file_id enumerate READING_MODULE_COMPRESSED so IMA can calculate the compressed kernel module data hash on READING_MODULE_COMPRESSED and defer appraising/measuring it until on READING_MODULE when the module has been decompressed. Before enabling in-kernel module decompression, a kernel module in initramfs can still be loaded with ima_policy=secure_boot. So adjust the kernel module rule in secure_boot policy to allow either an IMA signature OR an appended signature i.e. to use "appraise func=MODULE_CHECK appraise_type=imasig|modsig".

2025-11-19fs: move mntput_no_expire() slowpath into a dedicated routineMateusz Guzik
In the stock variant the compiler spills several registers on the stack and employs stack smashing protection, adding even more code + a branch on exit.. The actual fast path is small enough that the compiler inlines it for all callers -- the symbol is no longer emitted. Forcing noinline on it just for code-measurement purposes shows the fast path dropping from 111 to 39 bytes.
