The I2C core removes the manufacturer prefix from the compatible field so it reports to user-space the uevent i2c:rave-wdt, but this doesn't match with the i2c_device_id (i2c:ziirave-wdt) array so the module is not autoloaded. Correct the I2C device id to match with the reported uevent and fix the module autoloading functionality.

Without this check, the following XFS_I invocations would return bad pointers when used on non-XFS inodes (perhaps pointers into preceding allocator chunks). This could be used by an attacker to trick xfs_swap_extents into performing locking operations on attacker-chosen structures in kernel memory, potentially leading to code execution in the kernel. (I have not investigated how likely this is to be usable for an attack in practice.)

Fix a memory leak on probe error of the airspy usb device driver. The problem is triggered when more than 64 usb devices register with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV. The memory leak is caused by the probe function of the airspy driver mishandeling errors and not freeing the corresponding control structures when an error occours registering the device to v4l2 core. A badusb device can emulate 64 of these devices, and then through continual emulated connect/disconnect of the 65th device, cause the kernel to run out of RAM and crash the kernel, thus causing a local DOS vulnerability.

Now that we include the processor type in the pci_id_table structure we can skip the wrappers and just have the sbridge_get_all_devices() check the type to decide whether to allow duplicate devices and controllers to have registers spread across buses.

The VM_BUG_ON_PAGE in page_move_anon_rmap() is more trouble than it's worth: the syzkaller fuzzer hit it again. It's still wrong for some THP cases, because linear_page_index() was never intended to apply to addresses before the start of a vma. That's easily fixed with a signed long cast inside linear_page_index(); and Dmitry has tested such a patch, to verify the false positive. But why extend linear_page_index() just for this case? when the avoidance in page_move_anon_rmap() has already grown ugly, and there's no reason for the check at all (nothing else there is using address or index). Remove address arg from page_move_anon_rmap(), remove VM_BUG_ON_PAGE, remove CONFIG_DEBUG_VM PageTransHuge adjustment. And one more thing: should the compound_head(page) be done inside or outside page_move_anon_rmap()? It's usually pushed down to the lowest level nowadays (and mm/memory.c shows no other explicit use of it), so I think it's better done in page_move_anon_rmap() than by caller.

The previous patch addresses the race between split_huge_pmd_address() and someone changing the pmd. The fix is only for splitting of normal thp (i.e. pmd-mapped thp,) and for splitting of pte-mapped thp there still is the similar race. For splitting pte-mapped thp, the pte's conversion is done by try_to_unmap_one(TTU_MIGRATION). This function checks page_check_address() to get the target pte, but it can return NULL under some race, leading to VM_BUG_ON() in freeze_page(). Fortunately, page_check_address() already has an argument to decide whether we do a quick/racy check or not, so let's flip it when called from freeze_page().
