2021-11-11dt-bindings: Remove Netlogic bindingsRob Herring
Support for Netlogic was removed in commit 95b8a5e0111a ("MIPS: Remove NETLOGIC support"). Remove the now unused bindings. The GPIO binding also includes "brcm,vulcan-gpio", but it appears to be unused as well as Broadcom Vulkan became Cavium ThunderX2 which is ACPI based.

2021-11-11of: Support using 'mask' in making device bus idRob Herring
Commit 25b892b583cc ("ARM: dts: arm: Update register-bit-led nodes 'reg' and node names") added a 'reg' property to nodes. This change has the side effect of changing how the kernel generates the device name. The assumption was a translatable 'reg' address is unique. However, in the case of the register-bit-led binding (and a few others) that is not the case. The 'mask' property must also be used in this case to make a unique device name.

2021-11-12libata: add horkage for missing Identify Device logDamien Le Moal
ACS-3 introduced the ATA Identify Device Data log as mandatory. A warning message currently signals to the user if a device does not report supporting this log page in the log directory page, regardless of the ATA version of the device. Furthermore, this warning will appear for all attempts at accessing this missing log page during device revalidation. Since it is useless to constantly access the log directory and warn about this lack of support once we have discovered that the device does not support this log page, introduce the horkage flag ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for the Identify Device Data log page. Set this flag when ata_log_supported() returns false in ata_identify_page_supported(). The warning is printed only if the device ATA level is 10 or above (ACS-3 or above), and only once on device scan. With this flag set, the log directory page is not accessed again to test for Identify Device Data log page support.

2021-11-11Revert "PCI: Use to_pci_driver() instead of pci_dev->driver"Bjorn Helgaas
This reverts commit 2a4d9408c9e8b6f6fc150c66f3fef755c9e20d4a. Robert reported a NULL pointer dereference caused by the PCI core (local_pci_probe()) calling the i2c_designware_pci driver's .runtime_resume() method before the .probe() method. i2c_dw_pci_resume() depends on initialization done by i2c_dw_pci_probe(). Prior to 2a4d9408c9e8 ("PCI: Use to_pci_driver() instead of pci_dev->driver"), pci_pm_runtime_resume() avoided calling the .runtime_resume() method because pci_dev->driver had not been set yet. 2a4d9408c9e8 and b5f9c644eb1b ("PCI: Remove struct pci_dev->driver"), removed pci_dev->driver, replacing it by device->driver, which *has* been set by this time, so pci_pm_runtime_resume() called the .runtime_resume() method when it previously had not.

When BLKRESETZONE ioctl and data read race, the data read leaves stale page cache.

However, the stale page cache still can be read during the reset zone operation for the ioctl. To avoid the stale page cache completely, hold invalidate_lock of the block device file mapping.

2021-11-11blk-mq: don't grab ->q_usage_counter in blk_mq_sched_bio_mergeMing Lei
blk_mq_sched_bio_merge is only called from blk-mq.c:blk_attempt_bio_merge(), which is called when queue usage counter is grabbed already: 1) blk_mq_get_new_requests() 2) blk_mq_get_request() - cached request in current plug owns one queue usage counter So don't grab ->q_usage_counter in blk_mq_sched_bio_merge(), and more importantly this nest way causes hang in blk_mq_freeze_queue_wait().

2021-11-11mm/migrate.c: remove MIGRATE_PFN_LOCKEDAlistair Popple
MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a source page was already locked during migrate_vma_collect(). If it wasn't then the a second attempt is made to lock the page. However if the first attempt failed it's unlikely a second attempt will succeed, and the retry adds complexity. So clean this up by removing the retry and MIGRATE_PFN_LOCKED flag. Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag set, but nothing actually checks that.

2021-11-11mm: migrate: simplify the file-backed pages validation when migrating its ↵Baolin Wang
mapping There is no need to validate the file-backed page's refcount before trying to freeze the page's expected refcount, instead we can rely on the folio_ref_freeze() to validate if the page has the expected refcount before migrating its mapping. Moreover we are always under the page lock when migrating the page mapping, which means nowhere else can remove it from the page cache, so we can remove the xas_load() validation under the i_pages lock.

2021-11-11mm: allow only SLUB on PREEMPT_RTIngo Molnar
Memory allocators may disable interrupts or preemption as part of the allocation and freeing process. For PREEMPT_RT it is important that these sections remain deterministic and short and therefore don't depend on the size of the memory to allocate/ free or the inner state of the algorithm. Until v3.12-RT the SLAB allocator was an option but involved several changes to meet all the requirements. The SLUB design fits better with PREEMPT_RT model and so the SLAB patches were dropped in the 3.12-RT patchset. Comparing the two allocator, SLUB outperformed SLAB in both throughput (time needed to allocate and free memory) and the maximal latency of the system measured with cyclictest during hackbench. SLOB was never evaluated since it was unlikely that it preforms better than SLAB. During a quick test, the kernel crashed with SLOB enabled during boot. Disable SLAB and SLOB on PREEMPT_RT.
