Merge tag 'sched-core-2022-03-22' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull scheduler updates from Ingo Molnar:

- Cleanups for SCHED_DEADLINE

- Tracing updates/fixes

- CPU Accounting fixes

- First wave of changes to optimize the overhead of the scheduler
build, from the fast-headers tree - including placeholder *_api.h
headers for later header split-ups.

- Preempt-dynamic using static_branch() for ARM64

- Isolation housekeeping mask rework; preperatory for further changes

- NUMA-balancing: deal with CPU-less nodes

- NUMA-balancing: tune systems that have multiple LLC cache domains per
node (eg. AMD)

- Updates to RSEQ UAPI in preparation for glibc usage

- Lots of RSEQ/selftests, for same

- Add Suren as PSI co-maintainer

Merge branch 'sched/fast-headers' into sched/core

Merge the scheduler build speedup of the fast-headers tree.

Cumulative scheduler (kernel/sched/) build time speedup on a
Linux distribution's config, which enables all scheduler features,
compared to the vanilla kernel:

Summary:

- CPU time used to build the scheduler dropped by -60.9%, a reduction
from 22.1 clock-seconds to 8.7 clock-seconds.

- Wall-clock time to build the scheduler dropped by -3.9%, a reduction
from 2.95 seconds to 2.84 seconds.

sched/headers: Introduce kernel/sched/build_utility.c and build multiple .c files there

Collect all utility functionality source code files into a single kernel/sched/build_utility.c file,
via #include-ing the .c files:

kernel/sched/clock.c
kernel/sched/completion.c
kernel/sched/loadavg.c

CONFIG_MEMBARRIER:
kernel/sched/membarrier.c

CONFIG_CPU_ISOLATION:

CONFIG_SCHED_AUTOGROUP:

The goal is to amortize the 60+ KLOC header bloat from over a dozen build units into
a single build unit.

The build time of build_utility.c also roughly matches the build time of core.c and
fair.c - allowing better load-balancing of scheduler-only rebuilds.
