2025-02-25arm64: dts: mediatek: mt8390-genio-700: Add USB, TypeC Controller, MUXAngeloGioacchino Del Regno
This board features multiple USB connectors: * One Type-C connector with Power Delivery and Alt. Modes; * One MicroUSB connector, also used for bootloader SW download; * One USB through the RaspberryPi-compatible pins header. Add configuration for the MTU3 controllers providing OTG support with role switching both on the MicroUSB port, RPi pins header, and the Type-C port found on this board. Moreover, add the Richtek RT1715 Type-C Power Delivery Controller which manages current source/sink, linked to the iTE IT5205 Type-C Alternate Mode Passive Mux, handling both mode switching between USB (up to 3.1 Gen2 10Gbps) and DisplayPort (four lanes, DP1.4, op to 8.1Gbps) and plug orientation switching. All USB ports reside on different controller instances, and all of them support host or gadget and can be configured as desired at runtime.

2025-02-25arm64: dts: mediatek: mt8188: Add MTU3 nodes and correctly describe USBAngeloGioacchino Del Regno
The MT8188 SoC has three USB controllers, and all of them are behind the MTU3 DRD controller. Add the missing MTU3 nodes, default disabled, for all USB controllers and move the related XHCI nodes to be children of their MTU3 DRD to correctly describe the SoC. In order to retain USB functionality on all of the MT8188 and MT8390 boards, also move the vusb33 supply and enable the relevant MTU3 nodes with special attention to the MT8188 Geralt Chromebooks, where it was necessary to set the dr_mode of all MTU3 controllers to host to avoid interfering with the EC performing DRD on its own.

Add a port used to connect the SuperSpeed output endpoint to a Type-C connector. Note that the MediaTek XHCI controllers are always in front of a different controller handling the USB HS (usually, MTU3), so the only port that this controller provides is SuperSpeed, while the HighSpeed one comes from elsewhere.

2025-02-13arm64: dts: mediatek: mt8188: Assign apll1 clock as parent to avoid hangNícolas F. R. A. Prado
Certain registers in the AFE IO space require the apll1 clock to be enabled in order to be read, otherwise the machine hangs (registers like 0x280, 0x410 (AFE_GAIN1_CON0) and 0x830 (AFE_CONN0_5)). During AFE driver probe, when initializing the regmap for the AFE IO space those registers are read, resulting in a hang during boot. This has been observed on the Genio 700 EVK, Genio 510 EVK and MT8188-Geralt-Ciri Chromebook, all of which are based on the MT8188 SoC. Assign CLK_TOP_APLL1_D4 as the parent for CLK_TOP_A1SYS_HP, which is enabled during register read and write, to make sure the apll1 is enabled during register operations and prevent the MT8188 machines from hanging during boot.

2025-02-01mm/hugetlb: fix hugepage allocation for interleaved memory nodesRitesh Harjani (IBM)
gather_bootmem_prealloc() assumes the start nid as 0 and size as num_node_state(N_MEMORY). That means in case if memory attached numa nodes are interleaved, then gather_bootmem_prealloc_parallel() will fail to scan few of these nodes. Since memory attached numa nodes can be interleaved in any fashion, hence ensure that the current code checks for all numa node ids (.size = nr_node_ids). Let's still keep max_threads as N_MEMORY, so that it can distributes all nr_node_ids among the these many no. threads. e.g. qemu cmdline ======================== numa_cmd="-numa node,nodeid=1,memdev=mem1,cpus=2-3 -numa node,nodeid=0,cpus=0-1 -numa dist,src=0,dst=1,val=20" mem_cmd="-object memory-backend-ram,id=mem1,size=16G" w/o this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): ========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 0 kB with this patch for cmdline (default_hugepagesz=1GB hugepagesz=1GB hugepages=2): =========================== ~ # cat /proc/meminfo |grep -i huge AnonHugePages: 0 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 2 HugePages_Free: 2 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 2097152 kB Link: https://lkml.kernel.org/r/f8d8dad3a5471d284f54185f65d575a6aaab692b.1736592534.git.ritesh.list@gmail.com Fixes: b78b27d02930 ("hugetlb: parallelize 1G hugetlb initialization") Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> Reported-by: Pavithra Prakash <pavrampu@linux.ibm.com> Suggested-by: Muchun Song <muchun.song@linux.dev> Tested-by: Sourabh Jain <sourabhjain@linux.ibm.com> Reviewed-by: Luiz Capitulino <luizcap@redhat.com> Acked-by: David Rientjes <rientjes@google.com> Cc: Donet Tom <donettom@linux.ibm.com> Cc: Gang Li <gang.li@linux.dev> Cc: Daniel Jordan <daniel.m.jordan@oracle.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
2025-02-01mm: gup: fix infinite loop within __get_longterm_lockedZhaoyang Huang
We can run into an infinite loop in __get_longterm_locked() when collect_longterm_unpinnable_folios() finds only folios that are isolated from the LRU or were never added to the LRU. This can happen when all folios to be pinned are never added to the LRU, for example when vm_ops->fault allocated pages using cma_alloc() and never added them to the LRU. Fix it by simply taking a look at the list in the single caller, to see if anything was added.

Since nilfs_bmap_lookup_contig() in nilfs_fiemap() calculates its result by being prepared to go through potentially maxblocks == INT_MAX blocks, the value in n may experience an overflow caused by left shift of blkbits. While it is extremely unlikely to occur, play it safe and cast right hand expression to wider type to mitigate the issue.

2025-02-01mm: compaction: use the proper flag to determine watermarksyangge
There are 4 NUMA nodes on my machine, and each NUMA node has 32GB of memory. I have configured 16GB of CMA memory on each NUMA node, and starting a 32GB virtual machine with device passthrough is extremely slow, taking almost an hour. Long term GUP cannot allocate memory from CMA area, so a maximum of 16 GB of no-CMA memory on a NUMA node can be used as virtual machine memory. There is 16GB of free CMA memory on a NUMA node, which is sufficient to pass the order-0 watermark check, causing the __compaction_suitable() function to consistently return true. For costly allocations, if the __compaction_suitable() function always returns true, it causes the __alloc_pages_slowpath() function to fail to exit at the appropriate point. This prevents timely fallback to allocating memory on other nodes, ultimately resulting in excessively long virtual machine startup times. Call trace: __alloc_pages_slowpath if (compact_result == COMPACT_SKIPPED || compact_result == COMPACT_DEFERRED) goto nopage; // should exit __alloc_pages_slowpath() from here We could use the real unmovable allocation context to have __zone_watermark_unusable_free() subtract CMA pages, and thus we won't pass the order-0 check anymore once the non-CMA part is exhausted. There is some risk that in some different scenario the compaction could in fact migrate pages from the exhausted non-CMA part of the zone to the CMA part and succeed, and we'll skip it instead. But only __GFP_NORETRY allocations should be affected in the immediate "goto nopage" when compaction is skipped, others will attempt with DEF_COMPACT_PRIORITY anyway and won't fail without trying to compact-migrate the non-CMA pageblocks into CMA pageblocks first, so it should be fine. After this fix, it only takes a few tens of seconds to start a 32GB virtual machine with device passthrough functionality.

2025-02-01kernel: be more careful about dup_mmap() failures and uprobe registeringLiam R. Howlett
If a memory allocation fails during dup_mmap(), the maple tree can be left in an unsafe state for other iterators besides the exit path. All the locks are dropped before the exit_mmap() call (in mm/mmap.c), but the incomplete mm_struct can be reached through (at least) the rmap finding the vmas which have a pointer back to the mm_struct. Up to this point, there have been no issues with being able to find an mm_struct that was only partially initialised. Syzbot was able to make the incomplete mm_struct fail with recent forking changes, so it has been proven unsafe to use the mm_struct that hasn't been initialised, as referenced in the link below. Although 8ac662f5da19f ("fork: avoid inappropriate uprobe access to invalid mm") fixed the uprobe access, it does not completely remove the race. This patch sets the MMF_OOM_SKIP to avoid the iteration of the vmas on the oom side (even though this is extremely unlikely to be selected as an oom victim in the race window), and sets MMF_UNSTABLE to avoid other potential users from using a partially initialised mm_struct. When registering vmas for uprobe, skip the vmas in an mm that is marked unstable. Modifying a vma in an unstable mm may cause issues if the mm isn't fully initialised.

2025-02-01mm: kmemleak: fix upper boundary check for physical address objectsCatalin Marinas
Memblock allocations are registered by kmemleak separately, based on their physical address. During the scanning stage, it checks whether an object is within the min_low_pfn and max_low_pfn boundaries and ignores it otherwise. With the recent addition of __percpu pointer leak detection (commit 6c99d4eb7c5e ("kmemleak: enable tracking for percpu pointers")), kmemleak started reporting leaks in setup_zone_pageset() and setup_per_cpu_pageset(). These were caused by the node_data[0] object (initialised in alloc_node_data()) ending on the PFN_PHYS(max_low_pfn) boundary. The non-strict upper boundary check introduced by commit 84c326299191 ("mm: kmemleak: check physical address when scan") causes the pg_data_t object to be ignored (not scanned) and the __percpu pointers it contains to be reported as leaks. Make the max_low_pfn upper boundary check strict when deciding whether to ignore a physical address object and not scan it.
