Since commit 68fd110b ("kconfig: qconf: remove redundant help in the info view"), the help message is no longer displayed. I intended to drop duplicated "Symbol:", "Type:", but precious info about help and reverse dependencies was lost too. Revive it now. "defined at" is contained in menu_get_ext_help(), so I made sure to not display it twice. Fixes: 68fd110b ("kconfig: qconf: remove redundant help in the info view") Reported-by:

There is a race during page offline that can lead to infinite loop: a page never ends up on a buddy list and __offline_pages() keeps retrying infinitely or until a termination signal is received.

Ralph Campbell authored
A migrating transparent huge page has to already be unmapped. Otherwise, the page could be modified while it is being copied to a new page and data could be lost. The function __split_huge_pmd() checks for a PMD migration entry before calling __split_huge_pmd_locked() leading one to think that __split_huge_pmd_locked() can handle splitting a migrating PMD. However, the code always increments the page->_mapcount and adjusts the memory control group accounting assuming the page is mapped. Also, if the PMD entry is a migration PMD entry, the call to is_huge_zero_pmd(*pmd) is incorrect because it calls pmd_pfn(pmd) instead of migration_entry_to_pfn(pmd_to_swp_entry(pmd)). Fix these problems by checking for a PMD migration entry. Fixes: 84c3fc4e ("mm: thp: check pmd migration entry in common path") Signed-off-by:

5.8 commit 5d91f31f ("mm: swap: fix vmstats for huge page") has established that vm_events should count every subpage of a THP, including unevictable_pgs_culled and unevictable_pgs_rescued; but lru_cache_add_inactive_or_unevictable() was not doing so for unevictable_pgs_mlocked, and mm/mlock.c was not doing so for unevictable_pgs mlocked, munlocked, cleared and stranded. Fix them; but THPs don't go the pagevec way in mlock.c, so no fixes needed on that path. Fixes: 5d91f31f ("mm: swap: fix vmstats for huge page") Signed-off-by:

check_move_unevictable_pages() is used in making unevictable shmem pages evictable: by shmem_unlock_mapping(), drm_gem_check_release_pagevec() and i915/gem check_release_pagevec(). Those may pass down subpages of a huge page, when /sys/kernel/mm/transparent_hugepage/shmem_enabled is "force". That does not crash or warn at present, but the accounting of vmstats unevictable_pgs_scanned and unevictable_pgs_rescued is inconsistent: scanned being incremented on each subpage, rescued only on the head (since tails already appear evictable once the head has been updated). 5.8 commit 5d91f31f ("mm: swap: fix vmstats for huge page") has established that vm_events in general (and unevictable_pgs_rescued in particular) should count every subpage: so follow that precedent here. Do this in such a way that if mem_cgroup_page_lruvec() is made stricter (to check page->mem_cgroup is always set), no problem: skip the tails before calling it, and add thp_nr_pages() to vmstats on the head.

Patch series "mm: fixes to past from future testing". Here's a set of independent fixes against 5.9-rc2: prompted by testing Alex Shi's "warning on !memcg" and lru_lock series, but I think fit for 5.9 - though maybe only the first for stable. This patch (of 5): In 5.8 some instances of memcg charging in do_swap_page() and unuse_pte() were removed, on the understanding that swap cache is now already charged at those points; but a case was missed, when ksm_might_need_to_copy() has decided it must allocate a substitute page: such pages were never charged. Fix it inside ksm_might_need_to_copy(). This was discovered by Alex Shi's prospective commit "mm/memcg: warning on !memcg after readahead page charged". But there is a another surprise: this also fixes some rarer uncharged PageAnon cases, when KSM is configured in, but has never been activated. ksm_might_need_to_copy()'s anon_vma->root and linear_page_index() check sometimes catches a case which would need to have been copied if KSM were turned on. Or that's my optimistic interpretation (of my own old code), but it leaves some doubt as to whether everything is working as intended there - might it hint at rare anon ptes which rmap cannot find? A question not easily answered: put in the fix for missed memcg charges.

Commit c9b09a92 ("kconfig: qconf: use delete[] instead of delete to free array") fixed two lines, but there is one more. (cppcheck does not report it for some reason...) This was detected by Clang. "make HOSTCXX=clang++ xconfig" reports the following: scripts/kconfig/qconf.cc:1279:2: warning: 'delete' applied to a pointer that was allocated with 'new[]'; did you mean 'delete[]'? [-Wmismatched-new-delete] delete data; ^ [] scripts/kconfig/qconf.cc:1239:15: note: allocated with 'new[]' here char *data = new char[count + 1]; ^ Fixes: c4f7398b ("kconfig: qconf: make debug links work again") Fixes: c9b09a92 ("kconfig: qconf: use delete[] instead of delete to free array") Signed-off-by:

Commit e52d58d5 ("iommu/amd: Use cmpxchg_double() when updating 128-bit IRTE") removed an assumption that modify_irte_ga always set the valid bit, which requires the callers to set the appropriate value for the struct irte_ga.valid bit before calling the function. Similar to the commit 26e495f3 ("iommu/amd: Restore IRTE.RemapEn bit after programming IRTE"), which is for the function amd_iommu_deactivate_guest_mode(). The same change is also needed for the amd_iommu_activate_guest_mode(). Otherwise, this could trigger IO_PAGE_FAULT for the VFIO based VMs with AVIC enabled. Fixes: e52d58d5 ("iommu/amd: Use cmpxchg_double() when updating 128-bit IRTE") Reported-by:

Pull percpu fix from Dennis Zhou: "This is a fix for the first chunk size calculation where the variable length array incorrectly used the number of longs instead of bytes of longs. This came in as a code fix and not a bug report, so I don't think it was widely problematic. I believe it worked out due to it being memblock memory and alignment requirements working in our favor" * 'for-5.9-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: percpu: fix first chunk size calculation for populated bitmap
