Rename stack_depot_want_early_init to stack_depot_request_early_init.
The old name is confusing, as it hints at returning some kind of intention of stack depot. The new name reflects that this function requests an action from stack depot instead.

mm, slab/slub: Ensure kmem_cache_alloc_bulk() is available early
The memory allocators are available during early boot even in the phase where interrupts are disabled and scheduling is not yet possible.
The setup is so that GFP_KERNEL allocations work in this phase without causing might_alloc() splats to be emitted because the system state is SYSTEM_BOOTING at that point which prevents the warnings to trigger.
Most allocation/free functions use local_irq_save()/restore() or a lock variant of that. But kmem_cache_alloc_bulk() and kmem_cache_free_bulk() use local_[lock]_irq_disable()/enable(), which leads to a lockdep warning when interrupts are enabled during the early boot phase.
This went unnoticed so far as there are no early users of these interfaces. The upcoming conversion of the interrupt descriptor store from radix_tree to maple_tree triggered this warning as maple_tree uses the bulk interface.
Cure this by moving the kmem_cache_alloc/free() bulk variants of SLUB and SLAB to local[_lock]_irq_save()/restore().
There is obviously no reclaim possible and required at this point so there is no need to expand this coverage further.
No functional change.

Merge tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it, there is now a new family of functions that uses fast rejection sampling to choose properly uniformly random numbers within an interval:
get_random_u32_below(ceil) - [0, ceil) get_random_u32_above(floor) - (floor, U32_MAX] get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of prandom_u32_max(), as well as many open-coded patterns, resulting in improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused prandom_u32_max() function, just in case any other trees add a new use case of it that needs to converted. According to linux-next, there may be two trivial cases of prandom_u32_max() reintroductions that are fixable with a 's/.../.../'. So I'll have for you a final conversion patch doing that alongside the removal patch during the second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and wasn't entirely useful, so this has been replaced by code that works in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI variables, refreshing a variable with a fresh seed when the RNG is initialized. The RNG GUID namespace is then hidden from efivarfs to prevent accidental leakage.
These changes are split into random.c infrastructure code used in the EFI subsystem, in this pull request, and related support inside of EFISTUB, in Ard's EFI tree. These are co-dependent for full functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for an improvement to the way vsprintf initializes its siphash key, replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c input function, add_hwgenerator_randomness(), rather than sometimes going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork handler, but is a no-op when the latent entropy gcc plugin isn't used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed in beside the latent entropy variable. So now, if the latent entropy gcc plugin isn't enabled, add_latent_entropy() will expand to a call to add_device_randomness(NULL, 0), which adds a cycle counter, without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand when used. Always running from a worker allows it to make use of the CPU RNG on platforms like S390x, whose instructions are too slow to do so from interrupts. It also has the effect of adding in new inputs more frequently with more regularity, amounting to a long term transcript of random values. Plus, it helps a bit with the upcoming vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different CPUs, round-robining, in hopes of hitting even more memory latencies and other unpredictable effects. It also will mix in a cycle counter when the entropy timer fires, in addition to being mixed in from the main loop, to account more explicitly for fluctuations in that timer firing. And the state it touches is now kept within the same cache line, so that it's assured that the different execution contexts will cause latencies.

mm: slub: test: Use the kunit_get_current_test() function
Use the newly-added function kunit_get_current_test() instead of accessing current->kunit_test directly. This function uses a static key to return more quickly when KUnit is enabled, but no tests are actively running. There should therefore be a negligible performance impact to enabling the slub KUnit tests.
Other than the performance improvement, this should be a no-op.

Merge tag 'slab-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- SLOB deprecation and SLUB_TINY
The SLOB allocator adds maintenance burden and stands in the way of API improvements [1]. Deprecate it by renaming the config option (to make users notice) to CONFIG_SLOB_DEPRECATED with updated help text. SLUB should be used instead as SLAB will be the next on the removal list.
Based on reports from a riscv k210 board with 8MB RAM, add a CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the expense of scalability. This has resolved the k210 regression [2] so in case there are no others (that wouldn't be resolvable by further tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.
Existing defconfigs with CONFIG_SLOB are converted to CONFIG_SLUB_TINY.
- kmalloc() slub_debug redzone improvements
A series from Feng Tang that builds on the tracking or requested size for kmalloc() allocations (for caches with debugging enabled) added in 6.1, to make redzone checks consider the requested size and not the rounded up one, in order to catch more subtle buffer overruns. Includes new slub_kunit test.
- struct slab fields reordering to accomodate larger rcu_head
RCU folks would like to grow rcu_head with debugging options, which breaks current struct slab layout's assumptions, so reorganize it to make this possible.
- Miscellaneous improvements/fixes: - __alloc_size checking compiler workaround (Kees Cook) - Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes) - Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina) - Correct SLUB's percpu allocation estimates (Baoquan He) - Re-enableS LUB's run-time failslab sysfs control (Alexander Atanasov) - Make tools/vm/slabinfo more user friendly when not run as root (Rong Tao) - Dead code removal in SLUB (Hyeonggon Yoo)
