[merged] mm-memory_hotplug-dont-access-uninitialized-memmaps-in-shrink_zone_span.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/memory_hotplug: don't access uninitialized memmaps in shrink_zone_span() has been removed from the -mm tree. Its filename was mm-memory_hotplug-dont-access-uninitialized-memmaps-in-shrink_zone_span.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: mm/memory_hotplug: don't access uninitialized memmaps in shrink_zone_span() Let's limit shrinking to !ZONE_DEVICE so we can fix the current code. We should never try to touch the memmap of offline sections where we could have uninitialized memmaps and could trigger BUGs when calling page_to_nid() on poisoned pages. There is no reliable way to distinguish an uninitialized memmap from an initialized memmap that belongs to ZONE_DEVICE, as we don't have anything like SECTION_IS_ONLINE we can use similar to pfn_to_online_section() for !ZONE_DEVICE memory. E.g., set_zone_contiguous() similarly relies on pfn_to_online_section() and will therefore never set a ZONE_DEVICE zone consecutive. Stopping to shrink the ZONE_DEVICE therefore results in no observable changes, besides /proc/zoneinfo indicating different boundaries - something we can totally live with. Before commit d0dc12e86b31 ("mm/memory_hotplug: optimize memory hotplug"), the memmap was initialized with 0 and the node with the right value. So the zone might be wrong but not garbage. After that commit, both the zone and the node will be garbage when touching uninitialized memmaps. Toshiki reported a BUG (race between delayed initialization of ZONE_DEVICE memmaps without holding the memory hotplug lock and concurrent zone shrinking). https://lkml.org/lkml/2019/11/14/1040 "Iteration of create and destroy namespace causes the panic as below: [ 41.207694] kernel BUG at mm/page_alloc.c:535!

[PATCH] Revert "Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation"

by Lyude Paul

This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d. Ugh, I really dropped the ball on this one :\. So as it turns out RMI4 works perfectly fine on the X1 Extreme Gen 2 except for one thing I didn't notice because I usually use the trackpoint: clicking with the touchpad. Somehow this is broken, in fact we don't even seem to indicate BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even see any RMI4 events coming from the touchpad when I press down on it. This only seems to work for PS/2 mode. Since that means we have a regression, and PS/2 mode seems to work fine for the time being - revert this for now. We'll have to do a more thorough investigation on this.

This is because the driver avoids the gen3 speed bump when the parent bus speed isn't identical to gen3, 8.0GT/s. This is not compatible with gen4 and newer speeds. Fix by relaxing the test to explicitly look for the lower capability speeds which inherently allows for gen4 and all future speeds.

For things like page refcounts, KVM needs to treat ZONE_DEVICE pages like normal pages, e.g. put pages grabbed via gup(). But for flows such as setting A/D bits or shifting refcounts for transparent huge pages, KVM needs to to avoid processing ZONE_DEVICE pages as the flows in question lack the underlying machinery for proper handling of ZONE_DEVICE pages. This fixes a hang reported by Adam Borowski[*] in dev_pagemap_cleanup() when running a KVM guest backed with /dev/dax memory, as KVM straight up doesn't put any references to ZONE_DEVICE pages acquired by gup(). Note, Dan Williams proposed an alternative solution of doing put_page() on ZONE_DEVICE pages immediately after gup() in order to simplify the auditing needed to ensure is_zone_device_page() is called if and only if the backing device is pinned (via gup()). But that approach would break kvm_vcpu_{un}map() as KVM requires the page to be pinned from map() 'til unmap() when accessing guest memory, unlike KVM's secondary MMU, which coordinates with mmu_notifier invalidations to avoid creating stale page references, i.e. doesn't rely on pages being pinned.

However, try_to_unmap() acquires the page lock and so we must avoid recursively locking the pages ourselves -- which means that we cannot safely acquire the lock around set_page_dirty(). Since we can't be sure of the lock, we have to risk skip dirtying the page, or else risk calling set_page_dirty() without a lock and so risk fs corruption.
