Pull scheduler updates from Ingo Molnar:
"Core scheduler changes:

- Better tracking of maximum lag of tasks in presence of different
slices duration, for better handling of lag in the fair scheduler
(Vincent Guittot)

- Clean up and standardize #if/#else/#endif markers throughout the
entire scheduler code base (Ingo Molnar)

- Make SMP unconditional: build the SMP scheduler's data structures
and logic on UP kernel too, even though they are not used, to
simplify the scheduler and remove around 200 #ifdef/[#else]/#endif
blocks from the scheduler (Ingo Molnar)

- Reorganize cgroup bandwidth control interface handling for better
interfacing with sched_ext (Tejun Heo)

Balancing:

- Bump sd->max_newidle_lb_cost when newidle balance fails (Chris
Mason)

- Remove sched_domain_topology_level::flags to simplify the code
(Prateek Nayak)

- Simplify and clean up build_sched_topology() (Li Chen)

- Optimize build_sched_topology() on large machines (Li Chen)

Real-time scheduling:

- Add initial version of proxy execution: a mechanism for
mutex-owning tasks to inherit the scheduling context of higher
priority waiters.

Currently limited to a single runqueue and conditional on
CONFIG_EXPERT, and other limitations (John Stultz, Peter Zijlstra,
Valentin Schneider)

- Deadline scheduler (Juri Lelli):
- Fix dl_servers initialization order (Juri Lelli)
- Fix DL scheduler's root domain reinitialization logic (Juri
Lelli)
- Fix accounting bugs after global limits change (Juri Lelli)
- Fix scalability regression by implementing less agressive
dl_server handling (Peter Zijlstra)

PSI:

- Improve scalability by optimizing psi_group_change() cpu_clock()
usage (Peter Zijlstra)

Rust changes:

- Make Task, CondVar and PollCondVar methods inline to avoid
unnecessary function calls (Kunwu Chan, Panagiotis Foliadis)

- Add might_sleep() support for Rust code: Rust's "#[track_caller]"
mechanism is used so that Rust's might_sleep() doesn't need to be
defined as a macro (Fujita Tomonori)

- Introduce file_from_location() (Boqun Feng)

Debugging & instrumentation:

- Make clangd usable with scheduler source code files again (Peter
Zijlstra)

- tools: Add root_domains_dump.py which dumps root domains info (Juri
Lelli)

- tools: Add dl_bw_dump.py for printing bandwidth accounting info
(Juri Lelli)

Misc cleanups & fixes:

- Remove play_idle() (Feng Lee)

- Fix check_preemption_disabled() (Sebastian Andrzej Siewior)

- Do not call __put_task_struct() on RT if pi_blocked_on is set (Luis
Claudio R. Goncalves)

- Correct the comment in place_entity() (wang wei)"

Pull scheduler fix from Thomas Gleixner:
"A single fix for the scheduler.

A recent commit changed the runqueue counter nr_uninterruptible to an
unsigned int. Due to the fact that the counters are not updated on
migration of a uninterruptble task to a different CPU, these counters
can exceed INT_MAX.

The counter is cast to long in the load average calculation, which
means that the cast expands into negative space resulting in bogus
load average values.

Convert it back to unsigned long to fix this.

sched: Change nr_uninterruptible type to unsigned long

The commit e6fe3f422be1 ("sched: Make multiple runqueue task counters
32-bit") changed nr_uninterruptible to an unsigned int. But the
nr_uninterruptible values for each of the CPU runqueues can grow to
large numbers, sometimes exceeding INT_MAX. This is valid, if, over
time, a large number of tasks are migrated off of one CPU after going
into an uninterruptible state. Only the sum of all nr_interruptible
values across all CPUs yields the correct result, as explained in a
comment in kernel/sched/loadavg.c.

Change the type of nr_uninterruptible back to unsigned long to prevent
overflows, and thus the miscalculation of load average.

sched: Make clangd usable

Due to the weird Makefile setup of sched the various files do not
compile as stand alone units. The new generation of editors are trying
to do just this -- mostly to offer fancy things like completions but
also better syntax highlighting and code navigation.

Specifically, I've been playing around with neovim and clangd.

Setting up clangd on the kernel source is a giant pain in the arse
(this really should be improved), but once you do manage, you run into
dumb stuff like the above.

Fix up the scheduler files to at least pretend to work.
