2022-10-03Docs/admin-guide/mm/damon/usage: note DAMON debugfs interface deprecation planSeongJae Park1-0/+5
Commit b18402726bd1 ("Docs/admin-guide/mm/damon/usage: document DAMON sysfs interface") announced the DAMON debugfs interface deprecation plan, but it is not so aggressively announced. As the deprecation time is coming, this commit makes the announce more easy to be found by adding the note at the beginning of the DAMON debugfs interface usage document.

2022-10-03Docs/admin-guide/mm/damon/start: mention the dependency as sysfs instead of debugfsSeongJae Park1-10/+3
'Getting Started' document of DAMON says DAMON user-space tool, damo[1], is using DAMON debugfs interface, and therefore it needs to ensure debugfs is mounted. However, the latest version of the tool is using DAMON sysfs interface. Moreover, DAMON debugfs interface is going to be deprecated as announced by commit b18402726bd1 ("Docs/admin-guide/mm/damon/usage: document DAMON sysfs interface"). This commit therefore update the document to tell readers about DAMON sysfs interface dependency instead and never mention about debugfs interface, which will be deprecated.

2022-10-03Docs/admin-guide/mm/damon: rename the title of the documentSeongJae Park1-3/+3
The title of the DAMON document for admin-guide, 'Monitoring Data Accesses', could confuse readers in some ways. First of all, DAMON is not the only single way for data access monitoring. And the document is for not only the data access monitoring but also data access pattern based memory management optimizations (DAMOS). This commit updates the title to 'DAMON: Data Access MONitor', which more explicitly explains what the document describes.

2022-10-03kasan: dynamically allocate stack ring entriesAndrey Konovalov1-1/+3
Instead of using a large static array, allocate the stack ring dynamically via memblock_alloc(). The size of the stack ring is controlled by a new kasan.stack_ring_size command-line parameter. When kasan.stack_ring_size is not provided, the default value of 32 << 10 is used. When the stack trace collection is disabled via kasan.stacktrace=off, the stack ring is not allocated.

2022-10-03kasan: support kasan.stacktrace for SW_TAGSAndrey Konovalov1-6/+9
Add support for the kasan.stacktrace command-line argument for Software Tag-Based KASAN. The following patch adds a command-line argument for selecting the stack ring size, and, as the stack ring is supported by both the Software and the Hardware Tag-Based KASAN modes, it is natural that both of them have support for kasan.stacktrace too.

Pull RCU updates from Paul McKenney: - Documentation updates. This is the first in a series from an ongoing review of the RCU documentation. "Why are people thinking -that- about RCU? Oh. Because that is an entirely reasonable interpretation of its documentation." - Miscellaneous fixes. - Improved memory allocation and heuristics. - Improve rcu_nocbs diagnostic output. - Add full-sized polled RCU grace period state values. These are the same size as an rcu_head structure, which is double that of the traditional unsigned long state values that may still be obtained from et_state_synchronize_rcu(). The added size avoids missing overlapping grace periods. This benefit is that call_rcu() can be replaced by polling, which can be attractive in situations where RCU-protected data is aged out of memory. Early in the series, the size of this state value is three unsigned longs. Later in the series, the fastpaths in synchronize_rcu() and synchronize_rcu_expedited() are reworked to permit the full state to be represented by only two unsigned longs. This reworking slows these two functions down in SMP kernels running either on single-CPU systems or on systems with all but one CPU offlined, but this should not be a significant problem. And if it somehow becomes a problem in some yet-as-unforeseen situations, three-value state values can be provided for only those situations. Finally, a pair of functions named same_state_synchronize_rcu() and same_state_synchronize_rcu_full() allow grace-period state values to be compared for equality. This permits users to maintain lists of data structures having the same state value, removing the need for per-data-structure grace-period state values, thus decreasing memory footprint. - Polled SRCU grace-period updates, including adding tests to rcutorture and reducing the incidence of Tiny SRCU grace-period-state counter wrap. - Improve Tasks RCU diagnostics and quiescent-state detection. * tag 'rcu.2022.09.30a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: (55 commits) rcutorture: Use the barrier operation specified by cur_ops rcu-tasks: Make RCU Tasks Trace check for userspace execution rcu-tasks: Ensure RCU Tasks Trace loops have quiescent states rcu-tasks: Convert RCU_LOCKDEP_WARN() to WARN_ONCE() srcu: Make Tiny SRCU use full-sized grace-period counters srcu: Make Tiny SRCU poll_state_synchronize_srcu() more precise srcu: Add GP and maximum requested GP to Tiny SRCU rcutorture output rcutorture: Make "srcud" option also test polled grace-period API rcutorture: Limit read-side polling-API testing rcu: Add functions to compare grace-period state values rcutorture: Expand rcu_torture_write_types() first "if" statement rcutorture: Use 1-suffixed variable in rcu_torture_write_types() check rcu: Make synchronize_rcu() fastpath update only boot-CPU counters rcutorture: Adjust rcu_poll_need_2gp() for rcu_gp_oldstate field removal rcu: Remove ->rgos_polled field from rcu_gp_oldstate structure rcu: Make synchronize_rcu_expedited() fast path update .expedited_sequence rcu: Remove expedited grace-period fast-path forward-progress helper rcu: Make synchronize_rcu() fast path update ->gp_seq counters rcu-tasks: Remove grace-period fast-path rcu-tasks helper rcu: Set rcu_data structures' initial ->gpwrap value to true ...

ASoC: Updates for v6.1 This has been a very quiet release for the core but quite a busy one for drivers with a big crop of new drivers and lots of feature additions and fixes to existing ones: - A new string helper parse_int_array_user(). - Improvements to the SOF IPC4 code, especially around trace. - Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450 and Texas Instruments SRC4392 There is a conflict with the conversion of I2C remove functions to void in the cs42l42 driver which is fairly straightforward to resolve but should be highlighted to Linus.

2022-10-02kbuild: remove head-y syntaxMasahiro Yamada1-4/+5
Kbuild puts the objects listed in head-y at the head of vmlinux. Conventionally, we do this for head*.S, which contains the kernel entry point. A counter approach is to control the section order by the linker script. Actually, the code marked as __HEAD goes into the ".head.text" section, which is placed before the normal ".text" section. I do not know if both of them are needed. From the build system perspective, head-y is not mandatory. If you can achieve the proper code placement by the linker script only, it would be cleaner. I collected the current head-y objects into head-object-list.txt. It is a whitelist. My hope is it will be reduced in the long run.

2022-10-02kbuild: use obj-y instead extra-y for objects placed at the headMasahiro Yamada1-17/+1
The objects placed at the head of vmlinux need special treatments: - arch/$(SRCARCH)/Makefile adds them to head-y in order to place them before other archives in the linker command line. - arch/$(SRCARCH)/kernel/Makefile adds them to extra-y instead of obj-y to avoid them going into built-in.a. This commit gets rid of the latter. Create vmlinux.a to collect all the objects that are unconditionally linked to vmlinux. The objects listed in head-y are moved to the head of vmlinux.a by using 'ar m'. With this, arch/$(SRCARCH)/kernel/Makefile can consistently use obj-y for builtin objects. There is no *.o that is directly linked to vmlinux. Drop unneeded code in scripts/clang-tools/gen_compile_commands.py. $(AR) mPi needs 'T' to workaround the llvm-ar bug.
