Subject: [RESEND PATCH v4 0/4] sched: Miscellaneous isolation related cleanups
v4:
- Make "isolcpus=nohz" equivalent to "nohz_full" as suggested by
Federic.
- Update the scheduler code to use HK_TYPE_KERNEL_NOISE.
v3:
- Fix incorrect housekeeping_nohz_full_setup() flags setting.
v2:
- Remove HK_TYPE_SCHED and related dead code
- Change consolidated name from HK_TYPE_NOHZ_FULL to
HK_TYPE_KERNEL_NOSISE as suggested by Frederic and update
isolation.c as well.
This series contains a number of miscellaneous sched/isolation related
cleanups. Other than reducing the number of cpumasks in the housekeeping
structure, there should be no other functional change.

[v2] https://lore.kernel.org/lkml/20240904171441.1048072-1-longman@redhat.com/
[v3] https://lore.kernel.org/lkml/20240904183650.1053708-1-longman@redhat.com/
Waiman Long (4):
sched/core: Remove HK_TYPE_SCHED
sched/isolation: Make "isolcpus=nohz" equivalent to "nohz_full"
sched/isolation: Consolidate housekeeping cpumasks that are always
identical
sched: Unify HK_TYPE_{TIMER|TICK|MISC} to HK_TYPE_KERNEL_NOISE
