Patch series "Remove assumptions of THP size". There are a number of places in the VM which assume that a THP is a PMD in size. That's true today, and remains true after this patch series, but this is a prerequisite for switching to arbitrary-sized THPs. thp_nr_pages() still returns either HPAGE_PMD_NR or 1, but will be changed later. This patch (of 11): page_cache_free_page() assumes THPs are PMD_SIZE; fix that assumption. Signed-off-by:

When a THP is removed from the page cache by reclaim, we replace it with a shadow entry that occupies all slots of the XArray previously occupied by the THP. If the user then accesses that page again, we only allocate a single page, but storing it into the shadow entry replaces all entries with that one page. That leads to bugs like page dumped because: VM_BUG_ON_PAGE(page_to_pgoff(page) != offset) ------------[ cut here ]------------ kernel BUG at mm/filemap.c:2529! https://bugzilla.kernel.org/show_bug.cgi?id=206569 This is hard to reproduce with mainline, but happens regularly with the THP patchset (as so many more THPs are created). This solution is take from the THP patchset. It splits the shadow entry into order-0 pieces at the time that we bring a new page into cache.

In order to use multi-index entries for huge pages in the page cache, we need to be able to split a multi-index entry (eg if a file is truncated in the middle of a huge page entry). This version does not support splitting more than one level of the tree at a time. This is an acceptable limitation for the page cache as we do not expect to support order-12 pages in the near future.

Patch series "Fix read-only THP for non-tmpfs filesystems". As described more verbosely in the [3/3] changelog, we can inadvertently put an order-0 page in the page cache which occupies 512 consecutive entries. Users are running into this if they enable the READ_ONLY_THP_FOR_FS config option; see https://bugzilla.kernel.org/show_bug.cgi?id=206569 and Qian Cai has also reported it here: https://lore.kernel.org/lkml/20200616013309.GB815@lca.pw/ This is a rather intrusive way of fixing the problem, but has the advantage that I've actually been testing it with the THP patches, which means that it sees far more use than it does upstream -- indeed, Song has been entirely unable to reproduce it. It also has the advantage that it removes a few patches from my gargantuan backlog of THP patches. This patch (of 3): This function returns the order of the entry at the index. We need this because there isn't space in the shadow entry to encode its order. [akpm@linux-foundation.org: export xa_get_order to modules] Signed-off-by:

Saved write support was added to track the write bit of a pte after marking the pte protnone. This was done so that AUTONUMA can convert a write pte to protnone and still track the old write bit. When converting it back we set the pte write bit correctly thereby avoiding a write fault again. Hence enable the test only when CONFIG_NUMA_BALANCING is enabled and use protnone protflags.

powerpc used to set the pte specific flags in set_pte_at(). This is different from other architectures. To be consistent with other architecture update pfn_pte to set _PAGE_PTE on ppc64. Also, drop now unused pte_mkpte. We add a VM_WARN_ON() to catch the usage of calling set_pte_at() without setting _PAGE_PTE bit. We will remove that after a few releases. With respect to huge pmd entries, pmd_mkhuge() takes care of adding the _PAGE_PTE bit. [akpm@linux-foundation.org: whitespace fix, per Christophe] Signed-off-by:

The conversion to request_mem_region() is broken because it assumes that the range is marked busy prior to release. However, due to the way that the kmem driver manipulates the IORESOURCE_BUSY flag (clears it to let {add,remove}_memory() handle busy) it requires a manual release_resource() to perform cleanup. Given that the actual 'struct resource *' needs to be recalled, not just the range, add that tracking to the kmem driver-data.

Merge tag 'linux-kselftest-next-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull kselftest updates from Shuah Khan: - speed up headers_install done during selftest build - add generic make nesting support - add support to select individual tests: Selftests build/install generates run_kselftest.sh script to run selftests on a target system. Currently the script doesn't have support for selecting individual tests. Add support for it. With this enhancement, user can select test collections (or tests) individually. e.g: run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep Additionally adds a way to list all known tests with "-l", usage with "-h", and perform a dry run without running tests with "-n". * tag 'linux-kselftest-next-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: doc: dev-tools: kselftest.rst: Update examples and paths selftests/run_kselftest.sh: Make each test individually selectable selftests: Extract run_kselftest.sh and generate stand-alone test list selftests: Add missing gitignore entries selftests: more general make nesting support selftests: use "$(MAKE)" instead of "make" for headers_install

Kai-Heng Feng authored
Many laptops can be woken up from Suspend-to-Idle by touchpad. This is also the default behavior on other OSes. However, if touchpad and touchscreen contact to each other when lid is closed, wakeup events can be triggered inadventertly. So let's disable the wakeup by default, but enable the wakeup capability so users can enable it at their own discretion. Signed-off-by:

Pull sound updates from Takashi Iwai: "The amount of changes is smaller at this round (what a surprise), but lots of activity is seen.
