FROMLIST: ARM: NWFPE: avoid compiler-generated __aeabi_uldivmod
clang-15's ability to elide loops completely became more aggressive when it can deduce how a variable is being updated in a loop. Counting down one variable by an increment of another can be replaced by a modulo operation. For 64b variables on 32b ARM EABI targets, this can result in the compiler generating calls to __aeabi_uldivmod, which it does for a do while loop in float64_rem(). For the kernel, we'd generally prefer that developers not open code 64b division via binary / operators and instead use the more explicit helpers from div64.h. On arm-linux-gnuabi targets, failure to do so can result in linkage failures due to undefined references to __aeabi_uldivmod(). While developers can avoid open coding divisions on 64b variables, the compiler doesn't know that the Linux kernel has a partial implementation of a compiler runtime (--rtlib) to enforce this convention. It's also undecidable for the compiler whether the code in question would be faster to execute the loop vs elide it and do the 64b division. While I actively avoid using the internal -mllvm command line flags, I think we get better code than using barrier() here, which will force reloads+spills in the loop for all toolchains.

Merge tag 'x86_mm_for_v6.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 mm updates from Dave Hansen:
"There are some small things here, plus one big one.
The big one detected and refused to create W+X kernel mappings. This
caused a bit of trouble and it is entirely disabled on 32-bit due to
known unfixable EFI issues. It also oopsed on some systemd eBPF use,
which kept some users from booting.
The eBPF issue is fixed, but those troubles were caught relatively
recently which made me nervous that there are more lurking. The final
commit in here retains the warnings, but doesn't actually refuse to
create W+X mappings.
Summary:
- Detect insecure W+X mappings and warn about them, including a few
bug fixes and relaxing the enforcement
- Do a long-overdue defconfig update and enabling W+X boot-time
detection
- Cleanup _PAGE_PSE handling (follow-up on an earlier bug)
- Rename a change_page_attr function"

Pull more power management updates from Rafael Wysocki:
"These update the turbostat utility, extend the macros used for
defining device power management callbacks and add a diagnostic
message to the generic power domains code.
Specifics:
- Add an error message to be printed when a power domain marked as
"always on" is not actually on during initialization (Johan
Hovold).
- Extend macros used for defining power management callbacks to allow
conditional exporting of noirq and late/early suspend/resume PM
callbacks (Paul Cercueil).
- Update the turbostat utility:
- Add support for two new platforms (Zhang Rui).
- Adjust energy unit for Sapphire Rapids (Zhang Rui).
- Do not dump TRL if turbo is not supported (Artem Bityutskiy)"

More ACPI updates for 6.1-rc1
- Fix ACPI device object reference counting in (recently updated)
skl_int3472_fill_clk_pdata() (Andy Shevchenko).
- Fix a memory leak in APEI by avoiding to add a task_work to kernel
threads running when an asynchronous error is detected (Shuai Xue).
- Add ACPI support for handling system wakeups via GPIO wake capable
IRQs in addition to GPEs (Raul E Rangel).
- Make the system reboot code put ACPI-enabled systems into the S5
(system off) state which is necessary for some platforms to work as
expected (Kai-Heng Feng).
- Make the white space usage in the ACPI thermal driver more consistent
and drop redundant code from it (Rafael Wysocki).

bitmap patches for v6.1-rc1
From Phil Auld:
drivers/base: Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES
From me:
cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
This series cleans that mess and adds new config FORCE_NR_CPUS that
allows to optimize cpumask subsystem if the number of CPUs is known
at compile-time.
From me:
lib: optimize find_bit() functions
Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT() macros.
From me:
lib/find: add find_nth_bit()
Adds find_nth_bit(), which is ~70 times faster than bitcounting with
for_each() loop:
for_each_set_bit(bit, mask, size)
if (n-- == 0)
return bit;
Also adds bitmap_weight_and() to let people replace this pattern:
tmp = bitmap_alloc(nbits);
bitmap_and(tmp, map1, map2, nbits);
weight = bitmap_weight(tmp, nbits);
bitmap_free(tmp);
with a single bitmap_weight_and() call.
From me:
cpumask: repair cpumask_check()
After switching cpumask to use nr_cpu_ids, cpumask_check() started
generating many false-positive warnings. This series fixes it.
From Valentin Schneider:
bitmap,cpumask: Add for_each_cpu_andnot() and for_each_cpu_andnot()

Merge tag 'bitmap-6.1-rc1' of https://github.com/norov/linux
Pull bitmap updates from Yury Norov:
- Fix unsigned comparison to -1 in CPUMAP_FILE_MAX_BYTES (Phil Auld)
- cleanup nr_cpu_ids vs nr_cpumask_bits mess (me)
This series cleans that mess and adds new config FORCE_NR_CPUS that
allows to optimize cpumask subsystem if the number of CPUs is known
at compile-time.
- optimize find_bit() functions (me)
Reworks find_bit() functions based on new FIND_{FIRST,NEXT}_BIT()
macros.
- add find_nth_bit() (me)
Adds find_nth_bit(), which is ~70 times faster than bitcounting with
for_each() loop:
for_each_set_bit(bit, mask, size)
if (n-- == 0)
return bit;
Also adds bitmap_weight_and() to let people replace this pattern:
tmp = bitmap_alloc(nbits);
bitmap_and(tmp, map1, map2, nbits);
weight = bitmap_weight(tmp, nbits);
bitmap_free(tmp);
with a single bitmap_weight_and() call.
- repair cpumask_check() (me)
After switching cpumask to use nr_cpu_ids, cpumask_check() started
generating many false-positive warnings. This series fixes it.
- Add for_each_cpu_andnot() and for_each_cpu_andnot() (Valentin
Schneider)
Extends the API with one more function and applies it in sched/core.

Tracing updates for 6.1:
Major changes:
- Changed location of tracing repo from personal git repo to:
git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git
- Added Masami Hiramatsu as co-maintainer
- Updated MAINTAINERS file to separate out FTRACE as it is
more than just TRACING.
Minor changes:
- Added Mark Rutland as FTRACE reviewer
- Updated user_events to make it on its way to remove the BROKEN tag.
The changes should now be acceptable but will run it through
a cycle and hopefully we can remove the BROKEN tag next release.
- Added filtering to eprobes
- Added a delta time to the benchmark trace event
- Have the histogram and filter callbacks called via a switch
statement instead of indirect functions. This speeds it up to
avoid retpolines.
- Add a way to wake up ring buffer waiters waiting for the
ring buffer to fill up to its watermark.
- New ioctl() on the trace_pipe_raw file to wake up ring buffer
waiters.
- Wake up waiters when the ring buffer is disabled.
A reader may block when the ring buffer is disabled,
but if it was blocked when the ring buffer is disabled
it should then wake up.
Fixes:
- Allow splice to read partially read ring buffer pages
Fixes splice never moving forward.
- Fix inverted compare that made the "shortest" ring buffer
wait queue actually the longest.
- Fix a race in the ring buffer between resetting a page when
a writer goes to another page, and the reader.
- Fix ftrace accounting bug when function hooks are added at
boot up before the weak functions are set to "disabled".
- Fix bug that freed a user allocated snapshot buffer when
enabling a tracer.
- Fix possible recursive locks in osnoise tracer
- Fix recursive locking direct functions
- And other minor clean ups and fixes

Modules changes for v6.1-rc1
There's only two pathes queued up for v6.1 for modules, these have been grinding on linux-next for at least 4 weeks now: * David Disseldorp's minor enhancement for sysfs compression string * Aaron Tomlin's debugfs interface to view unloaded tainted modules But there are other changes queued up for testing for the next merge window already. One change being still discussed, and *not* yet even close to testing on linux-next, but worth mentioning to put on your radar is the generalization of the bpf prog_pack thing. The idea with that is to generalize the iTLB gains seen with using huge pages on eBPF to other text uses on the kernel (modules, ftrace, kprobes). Song Liu is doing a good job following up on that difficult task as the semantics for the special permissions are crap, and it really hasn't been easy to put all this together. The latest effort can be read on his vmalloc_exec() patch series [0]. Aaron will have a fix posted soon for the debugfs interface for unloaded modules, when that comes I'll just bounce that to you as it should be merged.

Kbuild updates for v6.1
- Remove potentially incomplete targets when Kbuid is interrupted by
SIGINT etc. in case GNU Make may miss to do that when stderr is piped
to another program.
- Rewrite the single target build so it works more correctly.
- Fix rpm-pkg builds with V=1.
- List top-level subdirectories in ./Kbuild.
- Ignore auto-generated __kstrtab_* and __kstrtabns_* symbols in kallsyms.
- Avoid two different modules in lib/zstd/ having shared code, which
potentially causes building the common code as build-in and modular
back-and-forth.
- Unify two modpost invocations to optimize the build process.
- Remove head-y syntax in favor of linker scripts for placing particular
sections in the head of vmlinux.
- Bump the minimal GNU Make version to 3.82.
- Clean up misc Makefiles and scripts.

It's been gone for over 2 years now and this is the first we've heard of it, but userspace breakage is userspace breakage, so O_NONBLOCK is now back. - Use randomness from hardware RNGs much more often during early boot, at the same interval that crng reseeds are done, from Dominik. - A semantic change in hardware RNG throttling, so that the hwrng framework can properly feed random.c with randomness from hardware RNGs that aren't specifically marked as creditable. A related patch coming to you via Herbert's hwrng tree depends on this one, not to compile, but just to function properly, so you may want to merge this PULL before that one. - A fix to clamp credited bits from the interrupts pool to the size of the pool sample. This is mainly just a theoretical fix, as it'd be pretty hard to exceed it in practice. - Oracle reported that InfiniBand TCP latency regressed by around 10-15% after a change a few cycles ago made at the request of the RT folks, in which we hoisted a somewhat rare operation (1 in 1024 times) out of the hard IRQ handler and into a workqueue, a pretty common and boring pattern. It turns out, though, that scheduling a worker from there has overhead of its own, whereas scheduling a timer on that same CPU for the next jiffy amortizes better and doesn't incur the same overhead. I also eliminated a cache miss by moving the work_struct (and subsequently, the timer_list) to below a critical cache line, so that the more critical members that are accessed on every hard IRQ aren't split between two cache lines. - The boot-time initialization of the RNG has been split into two approximate phases: what we can accomplish before timekeeping is possible and what we can accomplish after. This winds up being useful so that we can use RDRAND to seed the RNG before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in addition to other early uses of randomness. The effect is that systems with RDRAND (or a bootloader seed) will never see any warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And kfence benefits from getting a better seed of its own. - Small systems without much entropy sometimes wind up putting some truncated serial number read from flash into hostname, so contribute utsname changes to the RNG, without crediting. - Add smaller batches to serve requests for smaller integers, and make use of them when people ask for random numbers bounded by a given compile-time constant. This has positive effects all over the tree, most notably in networking and kfence. - The original jitter algorithm intended (I believe) to schedule the timer for the next jiffy, not the next-next jiffy, yet it used mod_timer(jiffies + 1), which will fire on the next-next jiffy, instead of what I believe was intended, mod_timer(jiffies), which will fire on the next jiffy. So fix that. - Fix a comment typo, from William. * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: clear new batches when bringing new CPUs online random: fix typos in get_random_bytes() comment random: schedule jitter credit for next jiffy, not in two jiffies prandom: make use of smaller types in prandom_u32_max random: add 8-bit and 16-bit batches utsname: contribute changes to RNG random: use init_utsname() instead of utsname() kfence: use better stack hash seed random: split initialization into early step and later step random: use expired timer rather than wq for mixing fast pool random: avoid reading two cache lines on irq randomness random: clamp credited irq bits to maximum mixed random: throttle hwrng writes if no entropy is credited random: use hwgenerator randomness more frequently at early boot random: restore O_NONBLOCK support |

Merge tag 'slab-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab fixes from Vlastimil Babka:
- The "common kmalloc v4" series [1] by Hyeonggon Yoo.
While the plan after LPC is to try again if it's possible to get rid
of SLOB and SLAB (and if any critical aspect of those is not possible
to achieve with SLUB today, modify it accordingly), it will take a
while even in case there are no objections.
Meanwhile this is a nice cleanup and some parts (e.g. to the
tracepoints) will be useful even if we end up with a single slab
implementation in the future:
- Improves the mm/slab_common.c wrappers to allow deleting
duplicated code between SLAB and SLUB.
- Large kmalloc() allocations in SLAB are passed to page allocator
like in SLUB, reducing number of kmalloc caches.
- Removes the {kmem_cache_alloc,kmalloc}_node variants of
tracepoints, node id parameter added to non-_node variants.
- Addition of kmalloc_size_roundup()
The first two patches from a series by Kees Cook [2] that introduce
kmalloc_size_roundup(). This will allow merging of per-subsystem
patches using the new function and ultimately stop (ab)using ksize()
in a way that causes ongoing trouble for debugging functionality and
static checkers.
- Wasted kmalloc() memory tracking in debugfs alloc_traces
A patch from Feng Tang that enhances the existing debugfs
alloc_traces file for kmalloc caches with information about how much
space is wasted by allocations that needs less space than the
particular kmalloc cache provides.
- My series [3] to fix validation races for caches with enabled
debugging:
- By decoupling the debug cache operation more from non-debug
fastpaths, extra locking simplifications were possible and thus
done afterwards.
- Additional cleanup of PREEMPT_RT specific code on top, by Thomas
Gleixner.
- A late fix for slab page leaks caused by the series, by Feng
Tang.
- Smaller fixes and cleanups:
- Unneeded variable removals, by ye xingchen
- A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu

Preempt RT cleanups:
Introduce preempt_[dis|enable_nested() and use it to clean up various places which have open coded PREEMPT_RT conditionals. On PREEMPT_RT enabled kernels, spinlocks and rwlocks are neither disabling preemption nor interrupts. Though there are a few places which depend on the implicit preemption/interrupt disable of those locks, e.g. seqcount write sections, per CPU statistics updates etc. PREEMPT_RT added open coded CONFIG_PREEMPT_RT conditionals to disable/enable preemption in the related code parts all over the place. That's hard to read and does not really explain why this is necessary. Linus suggested to use helper functions (preempt_disable_nested() and preempt_enable_nested()) and use those in the affected places. On !RT enabled kernels these functions are NOPs, but contain a lockdep assert to validate that preemption is actually disabled to catch call sites which do not have preemption disabled.

Objtool changes for v6.1:
- Remove the "ANNOTATE_NOENDBR on ENDBR" warning: it's not
really useful and only found a non-bug false positive so far.
- Properly decode LOOP/LOOPE/LOOPNE, which were missing from
the x86 decoder. Because these instructions are rather
ineffective, they never showed up in compiler output,
but they are simple enough to support, so add them for
completeness.
- A bit more cross-arch preparatory work.

Pull perf events updates from Ingo Molnar:
"PMU driver updates:
- Add AMD Last Branch Record Extension Version 2 (LbrExtV2) feature
support for Zen 4 processors.
- Extend the perf ABI to provide branch speculation information, if
available, and use this on CPUs that have it (eg. LbrExtV2).
- Improve Intel PEBS TSC timestamp handling & integration.
- Add Intel Raptor Lake S CPU support.
- Add 'perf mem' and 'perf c2c' memory profiling support on AMD CPUs
by utilizing IBS tagged load/store samples.
- Clean up & optimize various x86 PMU details.
HW breakpoints:
- Big rework to optimize the code for systems with hundreds of CPUs
and thousands of breakpoints:
- Replace the nr_bp_mutex global mutex with the bp_cpuinfo_sem
per-CPU rwsem that is read-locked during most of the key
operations.
- Improve the O(#cpus * #tasks) logic in toggle_bp_slot() and
fetch_bp_busy_slots().
- Apply micro-optimizations & cleanups.
- Misc cleanups & enhancements"

ANDROID: Configure out the macros in android_kabi and android_vendor
Add one CONFIG to control removing the macros or not. On some platform, configureing out the macros removes the associated members from the structs, this reduces the object size of the slabs related with the structs, therefore reduces the total slab memory consumption of system. Besides, this also reduces vmlinux size a bit, therefore the total kernel memory size increses a bit. The macros are ANDROID_KABI_RESERVE, ANDROID_VENDOR_DATA, ANDROID_VENDOR_DATA_ARRAY, ANDROID_OEM_DATA, ANDROID_OEM_DATA_ARRAY.

ANDROID: GKI: rework the ANDROID_KABI_USE() macro to not use __UNIQUE()
The __UNIQUE_ID() macro causes problems as it turns out to not be
deterministic across different compiler runs as it relies on the
__COUNTER__ macro which could have been used on other .h files previous
to this .h file being included.
This shows up specifically when building with "LTO=thin" vs. "LTO=full"
as different build paths seem to be triggered.
As the structure name isn't really needed at all here, we were just
including it for older compilers that could not handle anonymous
structures in a union, just drop the whole thing which resolves the abi
naming issue.
