Merge tag 'core-entry-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tipPull generic entry code updates from Thomas Gleixner: - Make syscall user dispatching configurable Not all architectures can makes use of syscall user dispatching. Allow them to disable the feature completely. - Consolidate stack randomization for the generic entry code and the architectures using it. Stack randomization on syscall entry was sprinkled throughout the architecture specific low level entry code and in some cases at the wrong points, e.g. before establishing state, which violates the non-instrumentable constraints of that code. Clean this up by integrating stack randomization into the generic entry code helpers so that it is invoked at the earliest possible point right after establishing state and converting all generic entry code using architecture over. - Clean up the syscall number handling in the generic entry code. It works correctly for architectures which have a separate return value storage in pt_regs, but fails to distinguish the case where user space handed in -1 as syscall number from the case where the entry code rejects it by returning -1 to the callers. Aside of that the return value functionality of those interfaces is not really intuitive. Fix this by separating the decision to reject a syscall (user dispatch, ptrace, seccomp ...) from the potential modification of the syscall number through these mechanisms. This solves most of the problems for architectures which do not have a separate return value storage in pt_regs except for the case where a tracepoint has a BPF script or a probe attached which overwrite both the syscall number and the return value. But that's a problem which cannot be solved in the generic code, that only can be addressed by separating the storage model in the affected architectures.* tag 'core-entry-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) entry, treewide: Make syscall_enter_from_user_mode[_work]() indicate syscall execution entry: Make return type of syscall_trace_enter() bool entry: Rework trace_syscall_enter() entry: Rework syscall_audit_enter() syscall_user_dispatch: Introduce ARCH_SUPPORTS_SYSCALL_USER_DISPATCH entry: Fix seccomp bypass after ptrace with TSYNC x86/entry: Simplify the syscall number logic x86/entry: Get rid of the sys_ni_syscall() indirection x86/entry: Make syscall functions static ptrace, treewide: Rename ptrace_report_syscall_entry() to ptrace_report_syscall_permit_entry() seccomp, treewide: Rename and convert __secure_computing() to return boolean entry: Use syscall number instead of rereading it entry: Remove syscall_enter_from_user_mode() x86/syscall: Use [syscall_]enter_from_user_mode_randomize_stack() s390/syscall: Use enter_from_user_mode_randomize_stack() riscv/syscall: Use syscall_enter_from_user_mode_randomize_stack() powerpc/syscall: Use syscall_enter_from_user_mode_randomize_stack() loongarch/syscall: Use syscall_enter_from_user_mode_randomize_stack() entry: Provide [syscall_]enter_from_user_mode_randomize_stack() randomize_kstack: Provide add_random_kstack_offset_irqsoff() ...

This can be utilized for other purposes as well and has been designed carefully to avoid overhead for the regular fastpath.
