Since cond_resched() is not called in userspace, remove the redundant code
in userspace's list_sort() implementation.  This change eliminates the
unused 'count' variable and the associated logic for invoking cmp()
periodically, which was intended to trigger cond_resched() in kernel
space.

The removed code includes:
- Declaration and increment of the 'count' variable.
- Conditional invocation of cmp() based on 'count'.

This cleanup simplifies merge_final(), avoids unnecessary overhead, and
has no impact on the functionality of list_sort() in userspace.

lib/sort: optimize heapsort for handling final 2 or 3 elements

After building the heap, the code continuously pops two elements from the
heap until only 2 or 3 elements remain, at which point it switches back to
a regular heapsort with one element popped at a time.  However, to handle
the final 2 or 3 elements, an additional else-if statement in the while
loop was introduced, potentially increasing branch misses.  Moreover, when
there are only 2 or 3 elements left, continuing with regular heapify
operations is unnecessary as these cases are simple enough to be handled
with a single comparison and 1 or 2 swaps outside the while loop.

Eliminating the additional else-if statement and directly managing cases
involving 2 or 3 elements outside the loop reduces unnecessary conditional
branches resulting from the numerous loops and conditionals in heapify.

This optimization maintains consistent numbers of comparisons and swaps
for arrays with even lengths while reducing swaps and comparisons for
arrays with odd lengths from 2.5 swaps and 1 comparison to 1.5 swaps and 1
comparison.

cpumask: split out include/linux/cpumask_types.h

Many core headers, like sched.h, include cpumask.h mostly for struct
cpumask and cpumask_var_t.  Those are frequently used headers and
shouldn't pull more than the bare minimum.

11 months agosched: avoid using ilog2() in sched.h
Yury Norov [Tue, 28 May 2024 00:56:44 +0000 (17:56 -0700)]
sched: avoid using ilog2() in sched.h

<linux/sched.h> indirectly via cpumask.h path includes the ilog2.h header
to calculate ilog2(TASK_REPORT_MAX).  The following patches drops sched.h
dependency on cpumask.h, and to have a successful build, the header has to
be included explicitly.

sched.h is a frequently included header, and it's better to keep the
dependency list as small as possible.  So, instead of including ilog2.h
for a single BUILD_BUG_ON() check, the same check may be implemented by
taking exponent of the other part of equation.

MAINTAINERS: add linux/nodemask_types.h to BITMAP API

Patch series "Cleanup cpumask.h inclusion in core headers".

Many core headers include linux/cpumask.h for nothing, and some others
include it just for types.  We already have nodemask_types.h, and this
series adds cpumask_types.h to optimize core headers inclusion paths.

Interestingly, it doesn't improve on build time for me, but the headers
cleanup work should keep going.

This patch (of 6):

Commit bea32141764b ("nodemask: Split out include/linux/nodemask_types.h")
added the nodemask_types.h but didn't cover it with corresponding record
in the MAINTAINERS file.

Implement a type-safe interface for min_heap using strong type pointers
instead of void * in the data field.  This change includes adding small
macro wrappers around functions, enabling the use of __minheap_cast and
__minheap_obj_size macros for type casting and obtaining element size.
This implementation removes the necessity of passing element size in

macro for preallocating some elements.

perf/core: fix several typos

Patch series "treewide: Refactor heap related implementation", v6.

implementation.  Firstly, a type-safe interface has been added to the
min_heap, along with the introduction of several new functions to enhance
its functionality.  Additionally, the heap implementation for bcache and
bcachefs has been replaced with the generic min_heap implementation from
include/linux.  Furthermore, several typos have been corrected.

Previous discussion with Kent Overstreet:
https://lkml.kernel.org/ioyfizrzq7w7mjrqcadtzsfgpuntowtjdw5pgn4qhvsdp4mqqg@nrlek5vmisbu

This patch (of 16):

Replace 'artifically' with 'artificially'.
Replace 'irrespecive' with 'irrespective'.
Replace 'futher' with 'further'.
Replace 'sufficent' with 'sufficient'.

12 months agopwm: stm32: Fix calculation of prescaler
Uwe Kleine-König [Fri, 21 Jun 2024 14:37:13 +0000 (16:37 +0200)]
pwm: stm32: Fix calculation of prescaler

A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.

One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to

ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301

This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.

Fix the calculation accordingly and adapt the comment to match the new
algorithm.

With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.

RDMA/mlx5: Ensure created mkeys always have a populated rb_key

cachable and mmkey.rb_key together are used by mlx5_revoke_mr() to put the
MR/mkey back into the cache. In all cases they should be set correctly.

alloc_cacheable_mr() was setting cachable but not filling rb_key,

implicit_get_child_mr()/mlx5_ib_alloc_implicit_mr() failed to set cachable
