2022-09-26filemap: make the accounting of thrashing more consistentYang Yang
Once upon a time, we only support accounting thrashing of page cache. Then Joonsoo introduced workingset detection for anonymous pages and we gained the ability to account thrashing of them[1]. So let delayacct account both the thrashing of page cache and anonymous pages, this could make the codes more consistent and simpler.

2022-09-11page_ext: introduce boot parameter 'early_page_ext'Li Zhe
In commit 2f1ee0913ce5 ("Revert "mm: use early_pfn_to_nid in page_ext_init""), we call page_ext_init() after page_alloc_init_late() to avoid some panic problem. It seems that we cannot track early page allocations in current kernel even if page structure has been initialized early. This patch introduces a new boot parameter 'early_page_ext' to resolve this problem. If we pass it to the kernel, page_ext_init() will be moved up and the feature 'deferred initialization of struct pages' will be disabled to initialize the page allocator early and prevent the panic problem above. It can help us to catch early page allocations. This is useful especially when we find that the free memory value is not the same right after different kernel booting.

2022-09-11mm/page_owner.c: add llseek for page_ownerKassey Li
It is too slow to dump all the pages, in some usage we just want to dump a given start pfn, for example: a CMA range or a single page. To speed up and save time, this change allows specifying of a start pfn by adding llseek for page_owner.

2022-09-11memory tiering: rate limit NUMA migration throughputHuang Ying
In NUMA balancing memory tiering mode, if there are hot pages in slow memory node and cold pages in fast memory node, we need to promote/demote hot/cold pages between the fast and cold memory nodes. A choice is to promote/demote as fast as possible. But the CPU cycles and memory bandwidth consumed by the high promoting/demoting throughput will hurt the latency of some workload because of accessing inflating and slow memory bandwidth contention. A way to resolve this issue is to restrict the max promoting/demoting throughput. It will take longer to finish the promoting/demoting. But the workload latency will be better. This is implemented in this patch as the page promotion rate limit mechanism. The number of the candidate pages to be promoted to the fast memory node via NUMA balancing is counted, if the count exceeds the limit specified by the users, the NUMA balancing promotion will be stopped until the next second. A new sysctl knob kernel.numa_balancing_promote_rate_limit_MBps is added for the users to specify the limit.

2022-09-11mm/cma_debug: show complete cma name in debugfs directoriesCharan Teja Kalla
Currently only 12 characters of the cma name is being used as the debug directories where as the cma name can be of length CMA_MAX_NAME(=64) characters. One side problem with this is having 2 cma's with first common 12 characters would end up in trying to create directories with same name and fails with -EEXIST thus can limit cma debug functionality. The 'cma-' prefix is used initially where cma areas don't have any names and are represented by simple integer values. Since now each cma would be having its own name, drop 'cma-' prefix for the cma debug directories as they are clearly evident that they are for cma debug through creating them in /sys/kernel/debug/cma/ path.

2022-08-26wait_on_bit: add an acquire memory barrierMikulas Patocka
There are several places in the kernel where wait_on_bit is not followed by a memory barrier (for example, in drivers/md/dm-bufio.c:new_read). On architectures with weak memory ordering, it may happen that memory accesses that follow wait_on_bit are reordered before wait_on_bit and they may return invalid data. Fix this class of bugs by introducing a new function "test_bit_acquire" that works like test_bit, but has acquire memory ordering semantics.

2022-08-23arm64: errata: add detection for AMEVCNTR01 incrementing incorrectlyIonela Voinescu
The AMU counter AMEVCNTR01 (constant counter) should increment at the same rate as the system counter. On affected Cortex-A510 cores, AMEVCNTR01 increments incorrectly giving a significantly higher output value. This results in inaccurate task scheduler utilization tracking and incorrect feedback on CPU frequency. Work around this problem by returning 0 when reading the affected counter in key locations that results in disabling all users of this counter from using it either for frequency invariance or as FFH reference counter. This effect is the same to firmware disabling affected counters. Details on how the two features are affected by this erratum: - AMU counters will not be used for frequency invariance for affected CPUs and CPUs in the same cpufreq policy. AMUs can still be used for frequency invariance for unaffected CPUs in the system. Although unlikely, if no alternative method can be found to support frequency invariance for affected CPUs (cpufreq based or solution based on platform counters) frequency invariance will be disabled. Please check the chapter on frequency invariance at Documentation/scheduler/sched-capacity.rst for details of its effect. - Given that FFH can be used to fetch either the core or constant counter values, restrictions are lifted regarding any of these counters returning a valid (!0) value. Therefore FFH is considered supported if there is a least one CPU that support AMUs, independent of any counters being disabled or affected by this erratum. Clarifying comments are now added to the cpc_ffh_supported(), cpu_read_constcnt() and cpu_read_corecnt() functions. The above is achieved through adding a new erratum: ARM64_ERRATUM_2457168.

2022-08-23arm64: fix rodata=fullMark Rutland
On arm64, "rodata=full" has been suppored (but not documented) since commit: c55191e96caa9d78 ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well") As it's necessary to determine the rodata configuration early during boot, arm64 has an early_param() handler for this, whereas init/main.c has a __setup() handler which is run later. Unfortunately, this split meant that since commit: f9a40b0890658330 ("init/main.c: return 1 from handled __setup() functions") ... passing "rodata=full" would result in a spurious warning from the __setup() handler (though RO permissions would be configured appropriately). Further, "rodata=full" has been broken since commit: 0d6ea3ac94ca77c5 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()") ... which caused strtobool() to parse "full" as false (in addition to many other values not documented for the "rodata=" kernel parameter. This patch fixes this breakage by: * Moving the core parameter parser to an __early_param(), such that it is available early. * Adding an (optional) arch hook which arm64 can use to parse "full". * Updating the documentation to mention that "full" is valid for arm64. * Having the core parameter parser handle "on" and "off" explicitly, such that any undocumented values (e.g. typos such as "ful") are reported as errors rather than being silently accepted. Note that __setup() and early_param() have opposite conventions for their return values, where __setup() uses 1 to indicate a parameter was handled and early_param() uses 0 to indicate a parameter was handled.

Older Intel CPUs that are not in the affected processor list for MMIO Stale Data vulnerabilities currently report "Not affected" in sysfs, which may not be correct. Vulnerability status for these older CPUs is unknown. Add known-not-affected CPUs to the whitelist.

2022-08-16locking/atomic: Make test_and_*_bit() ordered on failureHector Martin
These operations are documented as always ordered in include/asm-generic/bitops/instrumented-atomic.h, and producer-consumer type use cases where one side needs to ensure a flag is left pending after some shared data was updated rely on this ordering, even in the failure case. This is the case with the workqueue code, which currently suffers from a reproducible ordering violation on Apple M1 platforms (which are notoriously out-of-order) that ends up causing the TTY layer to fail to deliver data to userspace properly under the right conditions. This change fixes that bug. Change the documentation to restrict the "no order on failure" story to the _lock() variant (for which it makes sense), and remove the early-exit from the generic implementation, which is what causes the missing barrier semantics in that case. Without this, the remaining atomic op is fully ordered (including on ARM64 LSE, as of recent versions of the architecture spec).

2022-08-15dt-bindings: thermal: Fix missing required propertyDaniel Lezcano
When the thermal zone description was converted to yaml schema, the required 'trips' property was forgotten. The initial text bindings was describing: " [ ... ] * Thermal zone nodes The thermal zone node is the node containing all the required info for describing a thermal zone, including its cooling device bindings. The thermal zone node must contain, apart from its own properties, one sub-node containing trip nodes and one sub-node containing all the zone cooling maps. Required properties: - polling-delay: The maximum number of milliseconds to wait between polls Type: unsigned when checking this thermal zone. Size: one cell - polling-delay-passive: The maximum number of milliseconds to wait Type: unsigned between polls when performing passive cooling. Size: one cell - thermal-sensors: A list of thermal sensor phandles and sensor specifier Type: list of used while monitoring the thermal zone. phandles + sensor specifier - trips: A sub-node which is a container of only trip point nodes Type: sub-node required to describe the thermal zone. Optional property: - cooling-maps: A sub-node which is a container of only cooling device Type: sub-node map nodes, used to describe the relation between trips and cooling devices. [ ... ] " Now the schema describes: " [ ... ] required: - polling-delay - polling-delay-passive - thermal-sensors [ ... ] " Add the missing 'trips' property in the required properties.

2022-08-12dt-bindings: gpio: sifive: add gpio-line-namesAtul Khare
Fix device tree schema validation messages like 'gpio-line-names' does not match any of the regexes: 'pinctrl-[0-9]+' From schema: ... sifive,gpio.yaml'. The bindings were missing the gpio-line-names element, which was causing the dt-schema checker to trip-up.

2022-08-12xen-blkfront: Apply 'feature_persistent' parameter when connectSeongJae Park
In some use cases[1], the backend is created while the frontend doesn't support the persistent grants feature, but later the frontend can be changed to support the feature and reconnect. In the past, 'blkback' enabled the persistent grants feature since it unconditionally checked if frontend supports the persistent grants feature for every connect ('connect_ring()') and decided whether it should use persistent grans or not. However, commit aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent grants") has mistakenly changed the behavior. It made the frontend feature support check to not be repeated once it shown the 'feature_persistent' as 'false', or the frontend doesn't support persistent grants. Similar behavioral change has made on 'blkfront' by commit 74a852479c68 ("xen-blkfront: add a parameter for disabling of persistent grants"). This commit changes the behavior of the parameter to make effect for every connect, so that the previous behavior of 'blkfront' can be restored.
