2024-01-15spinlock: Fix failing build for PREEMPT_RTheader_cleanup-2024-01-20header_cleanupLeonardo Bras
Since 1d71b30e1f85 ("sched.h: Move (spin|rwlock)_needbreak() to spinlock.h") build fails for PREEMPT_RT, since there is no definition available of either spin_needbreak() and rwlock_needbreak(). Since it was moved on the mentioned commit, it was placed inside a !PREEMPT_RT part of the code, making it out of reach for an RT kernel. Fix this by moving code it a few lines down so it can be reached by an RT build, where it can also make use of the *_is_contended() definition added by the spinlock_rt.h.

2023-12-27rseq: Split out rseq.h from sched.hKent Overstreet
We're trying to get sched.h down to more or less just types only, not code - rseq can live in its own header. This helps us kill the dependency on preempt.h in sched.h. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-12-27LoongArch: signal.c: add header file to fix build errorRandy Dunlap
loongarch's signal.c uses rseq_signal_deliver() so it should pull in the appropriate header to prevent a build error: ../arch/loongarch/kernel/signal.c: In function 'handle_signal': ../arch/loongarch/kernel/signal.c:1034:9: error: implicit declaration of function 'rseq_signal_deliver' [-Werror=implicit-function-declaration] 1034 | rseq_signal_deliver(ksig, regs); | ^~~~~~~~~~~~~~~~~~~ Fixes: b74baf4ad05b ("LoongArch: Add signal handling support") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Huacai Chen <chenhuacai@kernel.org> Cc: WANG Xuerui <kernel@xen0n.name> Cc: loongarch@lists.linux.dev Cc: Kent Overstreet <kent.overstreet@linux.dev> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-12-20restart_block: Trim includesKent Overstreet
We don't actually use any timekeeping types, no need to pull in time64.h. Also, sched.h uses restart_block; add it as a direct dependency. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-12-20nodemask: Split out include/linux/nodemask_types.hKent Overstreet
sched.h, which defines task_struct, needs nodemask_t - but sched.h is a frequently used header and ideally shouldn't be pulling in any more code that it needs to. This splits out nodemask_types.h which has the definition sched.h needs, which will avoid a circular header dependency in the alloc tagging patch series, and as a bonus should speed up kernel build times.
