Pull rseq fixes from Ingo Molnar:
- Fix overly spread-out RSEQ concurrency ID allocation pattern that
regressed certain workloads
- Fix RSEQ registration syscall behavior on -EFAULT errors when
CONFIG_DEBUG_RSEQ=y (This debug option is disabled on most
distributions)
* tag 'sched-urgent-2025-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
rseq: Fix rseq registration with CONFIG_DEBUG_RSEQ
sched: Compact RSEQ concurrency IDs with reduced threads and affinity
