2022-07-18doc: proc: fix the description to THPeligibleYang Shi1-1/+3
The THPeligible bit shows 1 if and only if the VMA is eligible for allocating THP and the THP is also PMD mappable. Some misaligned file VMAs may be eligible for allocating THP but the THP can't be mapped by PMD. Make this more explicitly to avoid ambiguity.

2022-07-04mm/smaps: add Pss_DirtyVincent Whitchurch2-1/+5
Pss is the sum of the sizes of clean and dirty private pages, and the proportional sizes of clean and dirty shared pages: Private = Private_Dirty + Private_Clean Shared_Proportional = Shared_Dirty_Proportional + Shared_Clean_Proportional Pss = Private + Shared_Proportional The Shared*Proportional fields are not present in smaps, so it is not always possible to determine how much of the Pss is from dirty pages and how much is from clean pages. This information can be useful for measuring memory usage for the purpose of optimisation, since clean pages can usually be discarded by the kernel immediately while dirty pages cannot. The smaps routines in the kernel already have access to this data, so add a Pss_Dirty to show it to userspace. Pss_Clean is not added since it can be calculated from Pss and Pss_Dirty.

2022-07-04mm: memory_hotplug: make hugetlb_optimize_vmemmap compatible with ↵Muchun Song2-14/+13
memmap_on_memory For now, the feature of hugetlb_free_vmemmap is not compatible with the feature of memory_hotplug.memmap_on_memory, and hugetlb_free_vmemmap takes precedence over memory_hotplug.memmap_on_memory. However, someone wants to make memory_hotplug.memmap_on_memory takes precedence over hugetlb_free_vmemmap since memmap_on_memory makes it more likely to succeed memory hotplug in close-to-OOM situations. So the decision of making hugetlb_free_vmemmap take precedence is not wise and elegant. The proper approach is to have hugetlb_vmemmap.c do the check whether the section which the HugeTLB pages belong to can be optimized. If the section's vmemmap pages are allocated from the added memory block itself, hugetlb_free_vmemmap should refuse to optimize the vmemmap, otherwise, do the optimization. Then both kernel parameters are compatible. So this patch introduces VmemmapSelfHosted to mask any non-optimizable vmemmap pages. The hugetlb_vmemmap can use this flag to detect if a vmemmap page can be optimized.

2022-07-04mm: shrinkers: add scan interface for shrinker debugfsRoman Gushchin1-4/+35
Add a scan interface which allows to trigger scanning of a particular shrinker and specify memcg and numa node. It's useful for testing, debugging and profiling of a specific scan_objects() callback. Unlike alternatives (creating a real memory pressure and dropping caches via /proc/sys/vm/drop_caches) this interface allows to interact with only one shrinker at once. Also, if a shrinker is misreporting the number of objects (as some do), it doesn't affect scanning.

kmemleak_alloc_phys() Patch series "mm: kmemleak: store objects allocated with physical address separately and check when scan", v4. The kmemleak_*_phys() interface uses "min_low_pfn" and "max_low_pfn" to check address. But on some architectures, kmemleak_*_phys() is called before those two variables initialized. The following steps will be taken: 1) Add OBJECT_PHYS flag and rbtree for the objects allocated with physical address 2) Store physical address in objects if allocated with OBJECT_PHYS 3) Check the boundary when scan instead of in kmemleak_*_phys() This patch set will solve: https://lore.kernel.org/r/20220527032504.30341-1-yee.lee@mediatek.com https://lore.kernel.org/r/9dd08bb5-f39e-53d8-f88d-bec598a08c93@gmail.com v3: https://lore.kernel.org/r/20220609124950.1694394-1-patrick.wang.shcn@gmail.com v2: https://lore.kernel.org/r/20220603035415.1243913-1-patrick.wang.shcn@gmail.com v1: https://lore.kernel.org/r/20220531150823.1004101-1-patrick.wang.shcn@gmail.com This patch (of 4): Remove the unused kmemleak_not_leak_phys() function.

2022-06-17mm/memory-failure: disable unpoison once hw error happenszhenwei pi1-1/+2
Currently unpoison_memory(unsigned long pfn) is designed for soft poison(hwpoison-inject) only. Since 17fae1294ad9d, the KPTE gets cleared on a x86 platform once hardware memory corrupts. Unpoisoning a hardware corrupted page puts page back buddy only, the kernel has a chance to access the page with *NOT PRESENT* KPTE. This leads BUG during accessing on the corrupted KPTE. Suggested by David&Naoya, disable unpoison mechanism when a real HW error happens to avoid BUG like this: Unpoison: Software-unpoisoned page 0x61234 BUG: unable to handle page fault for address: ffff888061234000 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 2c01067 P4D 2c01067 PUD 107267063 PMD 10382b063 PTE 800fffff9edcb062 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 4 PID: 26551 Comm: stress Kdump: loaded Tainted: G M OE 5.18.0.bm.1-amd64 #7 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) ...

2022-06-10netfs: Further cleanups after struct netfs_inode wrapper introducedLinus Torvalds1-4/+5
Change the signature of netfs helper functions to take a struct netfs_inode pointer rather than a struct inode pointer where appropriate, thereby relieving the need for the network filesystem to convert its internal inode format down to the VFS inode only for netfslib to bounce it back up. For type safety, it's better not to do that (and it's less typing too). Give netfs_write_begin() an extra argument to pass in a pointer to the netfs_inode struct rather than deriving it internally from the file pointer. Note that the ->write_begin() and ->write_end() ops are intended to be replaced in the future by netfslib code that manages this without the need to call in twice for each page. netfs_readpage() and similar are intended to be pointed at directly by the address_space_operations table, so must stick to the signature dictated by the function pointers there.

2022-06-10dt-bindings: display: arm,malidp: remove bogus RQOS propertyAndre Przywara1-6/+1
As Liviu pointed out, the arm,malidp-arqos-high-level property mentioned in the original .txt binding was a mistake, and arm,malidp-arqos-value needs to take its place. The binding commit ce6eb0253cba ("dt/bindings: display: Add optional property node define for Mali DP500") mentions the right name in the commit message, but has the wrong name in the diff. Commit d298e6a27a81 ("drm/arm/mali-dp: Add display QoS interface configuration for Mali DP500") uses the property in the driver, but uses the shorter name. Remove the wrong property from the binding, and use the proper name in the example. The actual property was already documented properly.

2022-06-10dt-bindings: pinctrl: ralink: Fix 'enum' lists with duplicate entriesRob Herring2-25/+28
There's no reason to list the same value twice in an 'enum'. This was fixed treewide in commit c3b006819426 ("dt-bindings: Fix 'enum' lists with duplicate entries"), but this one got added in the merge window. A meta-schema change will catch future cases.
