2020-10-16mm/page_owner: change split_page_owner to take a countMatthew Wilcox (Oracle)
The implementation of split_page_owner() prefers a count rather than the old order of the page. When we support a variable size THP, we won't have the order at this point, but we will have the number of pages. So change the interface to what the caller and callee would prefer.

2020-10-16mm/filemap: fix page cache removal for arbitrary sized THPsMatthew Wilcox (Oracle)
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.

2020-10-16mm/filemap: fix storing to a THP shadow entryMatthew Wilcox (Oracle)
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.

2020-10-16XArray: add xas_splitMatthew Wilcox (Oracle)
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.

2020-10-16XArray: add xa_get_orderMatthew Wilcox (Oracle)
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.

2020-10-16device-dax/kmem: fix resource releaseDan Williams
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.

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.

2020-10-14powerpc32: don't adjust unmoved stack pointer in csum_partial_copy_generic() ↵Jason A. Donenfeld
epilogue A recent change to the checksum code removed usage of some extra arguments, alongside with storage on the stack for those, and the stack pointer no longer needed to be adjusted in the function prologue. But a left over subtraction wasn't removed in the function epilogue, causing the function to return with the stack pointer moved 16 bytes away from where it should have. This corrupted local state and lead to weird crashes. This simply removes the leftover instruction from the epilogue. Fixes: 70d65cd555c5 ("ppc: propagate the calling conventions change down to csum_partial_copy_generic()") Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jason A.
